By implementing segwit, it is already clear that all feerates in Bitcoin Core are denoted in (amount/virtual size). Though, there is inconsistency, as some places use kvB, some use kB. Thus, replace all with "kvB".

Pull request description:
Since #9319 proposed by Gregory Maxwell and released in v0.14, peers manually added through the `-addnode` config option or using the `addnode` RPC have their own separate limit of 8 connections that does not compete with other inbound or outbound connection usage and is not subject to the limitation imposed by the `-maxconnections` option.
This PR updates the `-addnode` and `-maxconnections` config options and the `addnode` RPC help docs with this information.
`-addnode` config option help
```
$ bitcoind -h | grep -A5 addnode=
-addnode=<ip>
Add a node to connect to and attempt to keep the connection open (see
the addnode RPC help for more info). This option can be specified
multiple times to add multiple nodes; connections are limited to
8 at a time and are counted separately from the -maxconnections
limit.
$ bitcoind -h | grep -A3 maxconnections=
-maxconnections=<n>
Maintain at most <n> connections to peers (default: 125). This limit
does not apply to connections manually added via -addnode or the
addnode RPC, which have a separate limit of 8.
```
`addnode` rpc help
```
$ bitcoin-cli help addnode
addnode "node" "command"
Attempts to add or remove a node from the addnode list.
Or try a connection to a node once.
Nodes added using addnode (or -connect) are protected from DoS disconnection and are not required to be
full nodes/support SegWit as other outbound peers are (though such peers will not be synced from).
Addnode connections are limited to 8 at a time and are counted separately from the -maxconnections limit.

Pull request description:
Store default values of RPC arguments in the corresponding type instead of a string. The value is then serialized when the help output is needed. This change simplifies #20017.
The following examples illustrates how to use the new `RPCArg::Default` and `RPCArg::DefaultHint`:
```diff
- {"verbose", RPCArg::Type::BOOL, /* default */ "false", "True for a json object, false for array of transaction ids"}
+ {"verbose", RPCArg::Type::BOOL, RPCArg::Default(false), "True for a json object, false for array of transaction ids"}
```
```diff
- {"nblocks", RPCArg::Type::NUM, /* default */ "one month", "Size of the window in number of blocks"}
+ {"nblocks", RPCArg::Type::NUM, RPCArg::DefaultHint("one month"), "Size of the window in number of blocks"}
```

Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
Based on:
- [x] #21270 | [Bundle 4/n] Prune g_chainman usage in validation-adjacent modules
- [x] #21525 | [Bundle 4.5/n] Followup fixups to bundle 4
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`

Pull request description:
This PR adds a `ban_duration` and `time_remaining` field to the `listbanned` RPC command. Thanks to jonatack, this PR also expands the `listbanned` test coverage to include these new fields
It's useful to keep track of `ban_duration` as this is another data point on which to sort banned peers. I found this helpful in adding additional context columns to the GUI `bantablemodel` as part of a follow-up PR. As [suggested](https://github.com/bitcoin/bitcoin/pull/21602#issuecomment-813486134) by jonatack, `time_remaining` is another useful user-centric data point.
Since a ban always expires after its created, the `ban_created` field is now placed before the `banned_until` field. This new ordering is more logical.
This PR also improves the `help listbanned` output by providing additional context to the descriptions of the `address`, `ban_created`, and `banned_until` fields.

Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.

Pull request description:
The existing functional test framework uses the `addnode` RPC to spin up manual connections between bitcoind nodes. This limits our ability to add integration tests for our networking code, which often executes different code paths for different connection types.
**This PR enables creating `outbound` & `block-relay-only` P2P connections in the functional tests.** This allows us to increase our p2p test coverage, since we can now verify expectations around these connection types.
This builds out the [prototype](https://github.com/bitcoin/bitcoin/issues/14210#issuecomment-527421978) proposed by ajtowns in #14210. 🙌🏽
An overview of this branch:
- introduces a new test-only RPC function `addconnection` which initiates opening an `outbound` or `block-relay-only` connection. (conceptually similar to `addnode` but for different connection types & restricted to regtest)
- adds `test_framework` support so a mininode can open an `outbound`/`block-relay-only` connection to a `P2PInterface`/`P2PConnection`.
- updates `p2p_blocksonly` tests to create a `block-relay-only` connection & verify expectations around transaction relay.
- introduces `p2p_add_connections` test that checks the behaviors of the newly introduced `add_outbound_p2p_connection` test framework function.
With these changes, there are many more behaviors that we can add integration tests for. The blocksonly updates is just one example.
Huge props to ajtowns for conceiving the approach & providing me feedback as I've built out this branch. Also thank you to jnewbery for lots of thoughtful input along the way.

Add a new RPC endpoint to enable opening outbound connections from
the tests. The functional test framework currently uses the addnode RPC, which
has different behavior than general outbound peers. These changes enable
creating both full-relay and block-relay-only connections. The new RPC
endpoint calls through to a newly introduced AddConnection method on
CConnman that ensures we stay within the allocated max.

Pull request description:
Fixes#19676, "_For every peer expose through getpeerinfo RPC whether or not we selected them as HB peers, and whether or not they selected us as HB peers._" See [BIP152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki), in particular the [protocol flow diagram](https://github.com/bitcoin/bips/raw/master/bip-0152/protocol-flow.png). The newly introduced states are changed on the following places in the code:
* on reception of a `SENDCMPCT` message with valid version, the field `m_highbandwidth_from` is changed depending on the first integer parameter in the message (1=high bandwidth, 0=low bandwidth), i.e. it just mirrors the field `CNodeState.fPreferHeaderAndIDs`.
* after adding a `SENDCMPCT` message to the send queue, the field `m_highbandwidth_to` is changed depending on how the first integer parameter is set (same as above)
Note that after receiving `VERACK`, the node also sends `SENDCMPCT`, but that is only to announce the preferred version and never selects high-bandwidth mode, hence there is no need to change the state variables there, which are initialized to `false` anyways.

> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

Pull request description:
This is basic info that is present in the GUI that I've been wishing to have exposed via the RPC and CLI without needing a bash workaround or script. For human users it would also be useful to have it in `-getinfo`.
`bitcoin-cli getnetworkinfo`
```
"connections": 15,
"connections_in": 6,
"connections_out": 9,
```
`bitcoin-cli -getinfo`
```
"connections": {
"in": 6,
"out": 9,
"total": 15
},
```
Update the tests, RPC help, and release notes for the changes. Also fixup the `getnettotals` timemillis help while touching `rpc/net.cpp`.
-----
Reviewers can manually test this PR by [building from source](https://jonatack.github.io/articles/how-to-compile-bitcoin-core-and-run-the-tests), launching bitcoind, and then running `bitcoin-cli -getinfo`, `bitcoin-cli getnetworkinfo`, `bitcoin-cli help getnetworkinfo`, and `bitcoin-cli help getnettotals` (for the UNIX epoch time change).

8e35bf5906 scripted-diff: rename misbehavior members (John Newbery)
1f96d2e673 [net processing] Move misbehavior tracking state to Peer (John Newbery)
7cd4159ac8 [net processing] Add Peer (John Newbery)
aba03359a6 [net processing] Remove CNodeState.name (John Newbery)
Pull request description:
We currently have two structures for per-peer data:
- `CNode` in net, which should just contain connection layer data (eg socket, send/recv buffers, etc), but currently also contains some application layer data (eg tx/block inventory).
- `CNodeState` in net processing, which contains p2p application layer data, but requires cs_main to be locked for access.
This PR adds a third struct `Peer`, which is for p2p application layer data, and doesn't require cs_main. Eventually all application layer data from `CNode` should be moved to `Peer`, and any data that doesn't strictly require cs_main should be moved from `CNodeState` to `Peer` (probably all of `CNodeState` eventually).
`Peer` objects are stored as shared pointers in a net processing global map `g_peer_map`, which is protected by `g_peer_mutex`. To use a `Peer` object, `g_peer_mutex` is locked, a copy of the shared pointer is taken, and the lock is released. Individual members of `Peer` are protected by different mutexes that guard related data. The lifetime of the `Peer` object is managed by the shared_ptr refcount.
This PR adds the `Peer` object and moves the misbehaving data from `CNodeState` to `Peer`. This allows us to immediately remove 15 `LOCK(cs_main)` instances.

fa459bdc87 rpc: Treat all args after a hidden arg as hidden as well (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in misc. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

a51d0ad2de rpc: Improve addnode remove command error message (Fabian Jahr)
Pull request description:
The `addnode` RPC with the `remove` command parameter is used to remove a node from the "added nodes". It did not have test coverage and in case of failure to remove the node it responded with the confusing message "Error: Node has not been added.".
This PR adds test coverage and introduces a new error code as well as changes the error message to something that makes sense.

37a480e0cd [net] Add addpeeraddress RPC method (John Newbery)
ae8051bbd8 [test] Test that getnodeaddresses() can return all known addresses (John Newbery)
f26502e9fc [addrman] Specify max addresses and pct when calling GetAddresses() (John Newbery)
Pull request description:
Currently addrman only allows a maximum of 1000 records or 23% of all records to be returned in a call to `GetAddr()`. Relax this limit and have the client specify the max records they want. For p2p, behaviour is unchanged (but the rate limiting is set inside net_processing, where it belongs). For RPC, `getnodeaddresses` can now return the complete addrman, which is helpful for testing and monitoring.
Also add a test-only RPC `addpeeraddress`, which adds an IP address:port to addrman. This is helpful for testing (eg #18991).

CAddrMan.GetAddr() would previously limit the number and percentage of
addresses returned (to ADDRMAN_GETADDR_MAX (1000) and
ADDRMAN_GETADDR_MAX_PCT (23) respectively). Instead, make it the callers
responsibility to specify the maximum addresses and percentage they want
returned.
For net_processing, the maximums are MAX_ADDR_TO_SEND (1000) and
MAX_PCT_ADDR_TO_SEND (23). For rpc/net, the maximum is specified by the
client.
This patch improves performance and resource usage around IP
addresses that are banned for misbehavior. They're already not
actually banned, as connections from them are still allowed,
but they are preferred for eviction if the inbound connection
slots are full.
Stop treating these like manually banned IP ranges, and instead
just keep them in a rolling Bloom filter of misbehaving nodes,
which isn't persisted to disk or exposed through the ban
framework. The effect remains the same: preferred for eviction,
avoided for outgoing connections, and not relayed to other peers.
Also change the name of this mechanism to better reflect reality;
they're not banned, just discouraged.
Contains release notes and several interface improvements by
John Newbery.
