sort_multisig test: check uncompressed keys are disallowed

wallet_labels: test addmultisigaddress fails if sort=true and (wallet) address is uncompressed
Instead of hardcoding the `pruneblockchain(<height>)` heights,
use 'getblockfileinfo' to obtain the highest block number of
each of the block files.
Making the test more robust and readable by stating which file
is being pruned at every point of time (the goal is to mimic
how the automatic pruning process work).

This RPC allows the client to retrieve the file system locations
of the confirmed blocks and their undo data, to allow building
efficient indexes outside of Bitcoin Core.
An example usage is described here:
https://github.com/romanz/electrs/issues/308
By using the new RPC, it is possible to build an address-based
index taking ~24GB and a txindex taking ~6GB (as of Dec. 2020).
`p2p_dns_seeds.py` would try to connect to the DNS server configured on
the machine and resolve `dummySeed.invalid`.
To block that configure an unavailable proxy which will be used also to
connect to the name server. The test needs 2 successful connections to
other peers (two Python `P2PInterface`s) and they work in spite of the
unavailable proxy because they are on `127.0.0.1` (`NET_UNROUTABLE`) and
the proxy is not used for that.

`feature_config_args.py` uses a proxy address of `1.2.3.4`. This results
in actually trying to open TCP connections over the internet to
`1.2.3.4:9050`.
The test does not need those to succeed so use `127.0.0.1:1` instead.
Also avoid `-noconnect=0` because that is interpreted as `-connect=1`
which is interpreted as `-connect=0.0.0.1` and a connection to
`0.0.0.1:18444` is attempted.

COPYRIGHT_YEAR + 2 years is used as the basis for expiration, to achieve a constantly-moving-forward expiration date.
The expiration can be disabled or extended with a debug-visibility "softwareexpiry" configuration option.
when `-v2onlyclearnet` is turned on:
- v1 connections to clearnet peers don't work
- v2 connections to clearnet peers work
- v1 conneections to tor/i2p/cjdns peer works
a proxy is used because otherwise NET_UNROUTABLE is the default
network in the tests.

After port collisions are no longer tolerated but lead to
a startup failure in v28.0, local setups of multiple nodes,
each with a different -port value would not be possible anymore
due to collision of the onion default port - even if the nodes
were using tor or not interested in receiving onion inbound connections.
Fix this by deriving the onion listening port to be -port + 1.

The primary objective is to provide users with clearer
and more informative error messages when encountering
the RPC_WALLET_NOT_SPECIFIED error, which occurs when
multiple wallets are loadad.
This commit also rectifies the error message consistency
by bringing the error message in line with the definition
established in protocol.h ("error when there are multiple
wallets loaded").

Exercising and verifying the following points:
1. An IBD node can sync headers from an AssumeUTXO node at
any time.
2. IBD nodes do not request historical blocks from AssumeUTXO
nodes while they are syncing the background-chain.
3. The assumeUTXO node dynamically adjusts the network services
it offers according to its state.
4. IBD nodes can fully sync from AssumeUTXO nodes after they
finish the background-chain sync.
Github-Pull: bitcoin/bitcoin#30807
Rebased-From: 992f83bb6f
Because AssumeUTXO nodes prioritize tip synchronization, they relay their local
address through the network before completing the background chain sync.
This, combined with the advertising of full-node service (NODE_NETWORK), can
result in an honest peer in IBD connecting to the AssumeUTXO node (while syncing)
and requesting an historical block the node does not have. This behavior leads to
an abrupt disconnection due to perceived unresponsiveness (lack of response)
from the AssumeUTXO node.
This lack of response occurs because nodes ignore getdata requests when they do
not have the block data available (further discussion can be found in PR 30385).
Fix this by refraining from signaling full-node service support while the
background chain is being synced. During this period, the node will only
signal 'NODE_NETWORK_LIMITED' support. Then, full-node ('NODE_NETWORK')
support will be re-enabled once the background chain sync is completed.

fa5b58ea01 test: Avoid intermittent block download timeout in p2p_ibd_stalling (MarcoFalke)
Pull request description:
Fixes#30704
The goal of the test is to check the stalling timeout, not the block download timeout.
On extremely slow hardware (for example qemu virtual hardware), downloading the 1023 blocks may take longer than the block download timeout.
Fix it by pinning the time using mocktime, and only advance it when testing the stalling timeout.

dd154b0568 consensus: lower regtest nPowTargetTimespan to 144 (Sjors Provoost)
Pull request description:
Because #30647 reduced the timewarp attack threshold from 7200s to 600s, our miner code will fail to propose a block template (on testnet4) if the last block of the previous period has a timestamp two hours in the future. This PR fixes that and also adds a test.
The non-test changes in the last commit should be in v28, otherwise miners have to patch it themselves. If necessary I can split that out into a separate PR, but I prefer to get the tests in as well.
In order to add the test, we activate BIP94 on regtest.
In order for the test to run faster, we reduce its difficulty retarget period to 144, the same number that's already used for softfork activation logic. Regtest does not actually adjust its difficulty, so this change has no effect (except for `getnetworkhashps`, see commit).
An alternative approach would be to run this test on testnet4, by hardcoding its first 2015 in the test suite. But since the timewarp mitigation is a serious candidate for a future mainnet softfork, it seems better to just deploy it on regtest.
The next commits add a test and fix the miner code.
The `MAX_TIMEWARP` constant is moved to `consensus.h` so both validation and miner code have access to it.

This PR is a small follow-up for #28052, adding support for the block linearization script to handle XORed blocksdir *.dat files. Note that if no xor.dat file exists, the XOR pattern is set to all-zeros, in order to still support blockdirs that have been created with versions earlier than 28.x.

6b2dcba076 wallet: List sqlite wallets with empty string name (Ava Chow)
3ddbdd1815 wallet: Ignore .bak files when listing wallet files (Ava Chow)
Pull request description:
When the default wallet is migrated, we do not rename the wallet so we end up having a descriptor wallet with the empty string as its name and the wallet.dat file in the root of the walletdir. This is supposed to be an unsupported configuration and there is no other way to achieve this (other than file copying), but the wallet loading code does not disallow loading such wallets. However `listwalletdir` does not currently list the default wallet if it is sqlite. This is confusing to users, so change `listwalletdir` to include these wallets.
Additionally, the migration of the default wallet, and of any plain wallet files in the walletdir, produces a backup file in the walletdir itself. Since these backups are a BDB file, `listwalletdir` will detect them as being another wallet that we could open, but this is erroneous and could lead to confusion and potentially funds loss if both the backup and the migrated wallet are in use simultaneously. To reduce the likelihood of this issue, don't list these wallets in `listwalletdir`.
***
Possibly we could have more stringent checks on loading to resolve these issues, but I'm concerned that that will just confuse users and gratuitously break things that already worked.
Since the original intent was to disallow default wallets for sqlite/descriptors, a possible alternative would be to prevent people from loading such wallets and change migration to rename those wallets. However, given that this behavior with migrating default wallets has existed since default wallet migration was fixed, I think that making such a change would be confusing and break things for no good reason. Although perhaps we should still do the renaming.
For the backups, we could also change loading to refuse to load any wallet named with `.bak` (or `.legacy.bak`) as such wallets can still be loaded by giving the path to them directly, which some users may do to "restore" the backup. However restricting what can be loaded based on filename seems a little heavyhanded. It wouldn't be funds loss though since the correct way to restore the backup is with `restorewallet`.

Although it is not explicitly possible to create a default wallet with
descriptors, it is possible to migrate a default wallet and have it end
up being a default wallet with descriptors. These wallets should be
listed by ListDatabases so that it appears in wallet directory listings
to avoid user confusion.
Migration creates backup files in the wallet directory with .bak as the
extension. This pollutes the output of listwalletdir with backup files
that most users should not need to care about.

0100907ca1 testnet: Add Testnet4 difficulty adjustment rules fix (Fabian Jahr)
74a04f9e7a testnet: Introduce Testnet4 (Fabian Jahr)
Pull request description:
To supplement the [ongoing conceptual discussion about a testnet reset](https://groups.google.com/g/bitcoindev/c/9bL00vRj7OU/m/9yCPo3uUBwAJ) I have drafted a move to v4 including a fix to the difficulty adjustment mechanism, which was part of the motivation that started the discussion.
Conceptual considerations:
- The conceptual discussion about doing a testnet4 or softforking the fix into testnet3 is outside of the scope of this PR and I would ask reviewers to contribute their opinions on this on the ML instead. However, I am happy to adapt this PR to a softfork change on testnet3 if there is consensus for that instead.
- The difficulty adjustment fix suggested here touches the `CalculateNextWorkRequired` function and uses the same logic used in `GetNextWorkRequired` to find the last previous block that was not mined with difficulty 1 under the exceptionf. An alternative fix briefly mentioned on the mailing list by Jameson Lopp would be to "restrict the special testnet minimum difficulty rule so that it can't be triggered on the block right before a difficulty retarget". That would also fix the issue but I find my suggestion here a bit more elegant.

fa7f7ac040 Return XOR AutoFile from BlockManager::Open*File() (MarcoFalke)
Pull request description:
Currently the *.dat files in the blocksdir store the data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan them and move them into quarantine, or delete them, or corrupt them. This may cause Bitcoin Core to fail a reorg, or fail to reply to block requests (via P2P, RPC, REST, ...).
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat files when writing or reading them.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat files. Any program that intentionally wants to mess with the dat files can still trivially do so.
The XOR pattern is only applied when the blocksdir is freshly created, and there is an option to disable it (on creation), so that people can disable it, if needed.
