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).
by skipping the part where we send a non-version message
before the version - this message would be interpreted as
part of the v2 handshake.

- "transport_protocol_type" of inbound peer before version handshake
is "detecting" on p2p v2 nodes (as opposed to "v1" for p2p v1)
- size of a ping/pong message is 29 bytes (as opposed to 32 for p2p v1)
- for the sendmsgtopeer RPC sub-test, enforce p2p v1 connection to
have a peer id of zero

Test that wallet rescans process transactions topologically, even if a
parent's entry into the mempool is later than that of its child.
This behavior is important because IsFromMe requires the ability to look
up a transaction's inputs.

Verifying the wallet updates the birth time accordingly when it
detects a transaction with a time older than the oldest descriptor
timestamp.
This could happen when the user blindly imports a descriptor with
'timestamp=now'.

Reduces the effective value of unconfirmed UTXOs by the fees necessary to bump their ancestor transactions to the same feerate.
While the individual UTXOs always account for their full ancestry before coin-selection, we can correct potential overestimates with a second pass where we establish the ancestry and bump fee for the whole input set collectively.

When a transaction uses an unconfirmed input, preceding this commit it
would not consider the feerate of the parent transaction. Given a parent
transaction with a lower ancestor feerate, this resulted in the new
transaction's ancestor feerate undershooting the target feerate.
This commit changes how we calculate the effective value of unconfirmed UTXOs.
The effective value of unconfirmed UTXOs is decreased by the fee
necessary to bump its ancestry to the target feerate. This also impacts
the calculation of the waste metric: since the estimate for the current
fee is increased by the bump fees, unconfirmed UTXOs current fees appear less
favorable compared to their unchanged long term fees.
This has one caveat: if multiple UTXOs have overlapping ancestries, each
of their individual estimates will account for bumping all ancestors.
b3a93b409e test: add functional test for deadlock situation (Martin Zumsande)
3557aa4d0a test: add basic tests for sendmsgtopeer to rpc_net.py (Martin Zumsande)
a9a1d69391 rpc: add test-only sendmsgtopeer rpc (Martin Zumsande)
Pull request description:
This adds a `sendmsgtopeer` rpc (for testing only) that allows a node to send a message (provided in hex) to a peer.
While we would usually use a `p2p` object instead of a node for this in the test framework, that isn't possible in situations where this message needs to trigger an actual interaction of multiple nodes.
Use this rpc to add test coverage for the bug fixed in #27981 (that just got merged):
The test lets two nodes (almost) simultaneously send a single large (4MB) p2p message to each other, which would have caused a deadlock previously (making this test fail), but succeeds now.
As can be seen from the discussion in #27981, it was not easy to reproduce this bug without `sendmsgtopeer`. I would imagine that `sendmsgtopeer` could also be helpful in various other test constellations.

9eac5a0529 [functional test] transaction orphan handling (glozow)
61e77bb901 [test framework] make it easier to fast-forward setmocktime (glozow)
Pull request description:
I was doing some mutation testing (through reckless refactoring) locally and found some specific behaviors in orphan handling that weren't picked up by tests. Adding some of these test cases now can maybe help with reviewing refactors like #28031.
- Parent requests aren't sent immediately. A delay is added and the requests are filtered by AlreadyHaveTx before they are sent, which means you can't use fake orphans to probe precise arrival timing of a tx.
- Parent requests include all that are not AlreadyHaveTx. This means old confirmed parents may be requested.
- The node does not give up on orphans if the peer responds to a parent request with notfound. This means that if a parent is an old confirmed transaction (in which notfound is expected), the orphan should still be resolved.
- Rejected parents can cause an orphan to be dropped, but it depends on the reason and only based on txid.
- Rejected parents can cause an orphan to be rejected too, by both wtxid and txid.
- Requests for orphan parents should be de-duplicated with "regular" txrequest. If a missing parent has the same hash as an in-flight request, it shouldn't be requested.
- Multiple orphans with overlapping parents should not cause duplicated parent requests.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27140
Adds test coverage for https://github.com/bitcoin/bitcoin/pull/20516 to ensure that https://github.com/bitcoin/bitcoin/issues/20511 is completed and may be closed.
This PR adds a test case to `feature_anchors.py` where an onion v3 address is set as a blocks-only relay peer and then shutdown, ensuring that the address is saved to anchors.dat in addrv2 format. We then ensure that bitcoin attempts to reconnect to that anchor address on restart.
To compute the addrv2 serialization of the onion v3 address, I added logic to `CAddress` in `messages.py`. This new logic is covered by extending `p2p_addrv2_relay.py` to include an onion v3 address. Future work will be adding coverage for ipv6, torv2 and cjdns in these modules and also `feature_proxy.py`
Also includes de/serialization unit test for `CAddress` in test framework.

After initially being merged in #20487, it's no-longer clear that an
internal syscall sandboxing mechanism is something that Bitcoin Core
should have/maintain, especially when compared to better
maintained/supported alterantives, i.e firejail.
Note that given where it's used, the sandbox also gets dragged into the
kernel.
There is some related discussion in #24771.
This should not require any sort of deprecation, as this was only ever
an opt-in, experimental feature.
Closes#24771.
cdba23db35 wallet: Document blank flag use in descriptor wallets (Ryan Ofsky)
43310200dc wallet: Ensure that the blank wallet flag is unset after imports (Andrew Chow)
e9379f1ffa rpc, wallet: Include information about blank flag (Andrew Chow)
Pull request description:
The `blank` wallet flag is used to indicate that the wallet intentionally does not have any keys, scripts, or descriptors, and it prevents the automatic generation of those things for such a wallet. Once the wallet contains any of those data, it is unnecessary, and possibly incorrect, to have `blank` set. This PR fixes a few places where this was not properly happening. It also adds a test for this unset behavior.

Pull request description:
This implements a fix for #7315. Previously when a block was disconnected any transactions that were conflicting with transactions mined in that block were not updated to be marked as inactive. The fix implemented here is described on the [Bitcoin DevWiki](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking#idea-refresh-conflicted). A test which tested the previous behavior has also been updated.

Test the case of a tx being conflicted by multiple
txs with different depths. The conflicted tx is also spent by
a child tx for which confirmation status is tied to the parent's.
After a reorg of conflicting txs, the conflicted status should be
undone properly.
