fa621ededd refactor: Pass script verify flags as uint32_t (MarcoFalke)
Pull request description:
The flags are cast to unsigned in the interpreter anyway, so avoid the confusion (and fuzz crashes) by just passing them as unsigned from the beginning.
Also, the flags are often inverted bit-wise with the `~` operator, which also works on signed integers, but might cause confusion as the sign bit is flipped.

9b85a5e2f7 tests: Test for dumpwallet lock order issue (Andrew Chow)
25d99e6511 Reorder dumpwallet so that cs_main functions go first (Andrew Chow)
Pull request description:
When a wallet is loaded which has an unconfirmed transaction in the mempool, it will end up establishing the lock order of cs_wallet -> cs_main -> cs_KeyStore. If `dumpwallet` is used on this wallet, then a lock order of cs_wallet -> cs_KeyStore -> cs_main will be used, which causes a lock order assertion. This PR fixes this by reordering `dumpwallet` and `GetKeyBirthTimes` (only used by `dumpwallet`). Specifically, in both functions, the function calls which lock cs_main are done prior to locking cs_KeyStore. This avoids the lock order issue.
Additionally, I have added a test case to `wallet_dump.py`. Of course testing this requires `--enable-debug`.

2837a9f1ea [mempool] Only add a transaction to the unbroadcast set when it's added to the mempool (John Newbery)
Pull request description:
1. Only add a transaction to the unbroadcast set when it's added to the mempool
Currently, if BroadcastTransaction() is called to rebroadcast a
transaction (e.g. by ResendWalletTransactions()), then we add the
transaction to the unbroadcast set. That transaction has already been
broadcast in the past, so peers are unlikely to request it again,
meaning RemoveUnbroadcastTx() won't be called and it won't be removed
from m_unbroadcast_txids.
Net processing will therefore continue to attempt rebroadcast for the
transaction every 10-15 minutes. This will most likely continue until
the node connects to a new peer which hasn't yet seen the transaction
(or perhaps indefinitely).
Fix by only adding the transaction to the broadcast set when it's added to the mempool.
2. Allow rebroadcast for same-txid-different-wtxid transactions
There is some slightly unexpected behaviour when:
- there is already transaction in the mempool (the "mempool tx")
- BroadcastTransaction() is called for a transaction with the same txid
as the mempool transaction but a different witness (the "new tx")
Prior to this commit, if BroadcastTransaction() is called with
relay=true, then it'll call RelayTransaction() using the txid/wtxid of
the new tx, not the txid/wtxid of the mempool tx. For wtxid relay peers,
in SendMessages(), the wtxid of the new tx will be taken from
setInventoryTxToSend, but will then be filtered out from the vector of
wtxids to announce, since m_mempool.info() won't find the transaction
(the mempool contains the mempool tx, which has a different wtxid from
the new tx).
Fix this by calling RelayTransaction() with the wtxid of the mempool
transaction in this case.
The third commit is a comment/whitespace only change to tidy up the BroadcastTransaction() function.

b6c5d1e450 p2p: AddrFetch - don't disconnect on self-announcements (Martin Zumsande)
Pull request description:
AddrFetch connections (old name: oneshots) are intended to be short-lived connections on which we ask a peer for addresses via `getaddr` and disconnect after receiving them.
This is done by disconnecting after receiving the first `addr`. However, it is no longer working as intended, because nowadays, the first `addr` a typical bitcoin core node sends is its self-announcement.
So we'll disconnect before the peer gets a chance to answer our `getaddr`.
I checked that this affects both `-seednode` peers specified manually, and DNS seeds when AddrFetch is used as a fallback if DNS doesn't work for us.
The current behavior of getting peers via AddrFetch when starting with an empty addrman would be to connect to the peer, receive its self-announcement and add it to addrman, disconnect, reconnect to the same peer again as a full outbound (no other addresses in addrman) and then receive more `addr`. This is silly and not in line with AddrFetch peer being intended to be short-lived peers.
Fix this by only disconnecting after receiving an `addr` message of size > 1.
[Edit] As per review discussion, this PR now also adds a timeout after which we disconnect if we haven't received any suitable `addr`, and a functional test.

- [x] Binary tarball option: prompt user to create `/etc/profile.d` entry and re-login
- [x] Fanquake docker option: complete section
- [x] Arch Linux AUR option: prompt to start `guix-daemon-latest` unit after finishing "optional setup" section
- [x] Building from source option: Insert dependency tree diagram that I made
- [x] Building from source option: redo sectioning, kind of a mess right now
- [x] Optional setup: make clear which parts are only needed if building from source
- [x] Workaround 1 for GnuTLS: perhaps mention how to remove Guix build farm's key
- [x] Overall (after everything): Make the links work.
Note to self: wherever possible, tell user how to check that something is true rather than branching by installation option.

Adds a test for the condition which can trigger a lock order assertion.
Specifically, there must be an unconfirmed transaction in the mempool
which belongs to the wallet being loaded. This will establish the order
of cs_wallet -> cs_main -> cs_KeyStore. Then dumpwallet is called on
that wallet. Previously, this would have used a lock order of cs_wallet
-> cs_KeyStore -> cs_main, but this should be fixed now. The test
ensures that.
DEBUG_LOCKORDER expects cs_wallet, cs_main, and cs_KeyStore to be
acquired in that order. However dumpwallet would take these in the order
cs_wallet, cs_KeyStore, cs_main. So when configured with
`--enable-debug`, it is possible to hit the lock order assertion when
using dumpwallet.
To fix this, cs_wallet and cs_KeyStore are no longer locked at the same
time. Instead cs_wallet will be locked first. Then the functions which
lock cs_main will be run. Lastly cs_KeyStore will be locked afterwards.
This avoids the lock order issue.
Furthermore, since GetKeyBirthTimes (only used by dumpwallet) also uses
a function that locks cs_main, and itself also locks cs_KeyStore, the
same reordering is done here.

Pull request description:
The rate at which IP addresses are rumoured (through ADDR and ADDRV2 messages) on the network seems to vary from 0 for some non-participating nodes, to 0.005-0.025 addr/s for recent Bitcoin Core nodes. However, the current codebase will happily accept and process an effectively unbounded rate from attackers. There are measures to limit the influence attackers can have on the addrman database (bucket restrictions based on source IPs), but still - there is no need to permit them to feed us addresses at a rate that's orders of magnitude larger than what is common on the network today, especially as it will cause us to spam our peers too.
This PR implements a [token bucket](https://en.wikipedia.org/wiki/Token_bucket) based rate limiter, allowing an average of 0.1 addr/s per connection, with bursts up to 1000 addresses at once. Whitelisted peers as well as responses to GETADDR requests are exempt from the limit. New connections start with 1 token, so as to not interfere with the common practice of peers' self-announcement.

Keeping the declarations of these non-template fuzz helpers in `util.h` and moving their implementations to `util.cpp` will skip the redundant recompilation of all the fuzz tests, and builds these helpers only once in `util.cpp`.
Functions moved from `util.h` to `util.cpp`:

- makes it easy to integrate [new modules](https://github.com/bitcoin/bitcoin/pull/16883) into static builds
- has the minimal diff
- makes the qt package build process streamlined by dropping some patches and hacks (an alternative to #21420 and #20642)
Fixes#18536 (a non-intrusive alternative to #21589 and #19785).
Fixes#14648.
Fixes#21588 (a non-intrusive alternative to #21591).

fb7be92b09 Mark print-% target as phony. (Dmitry Goncharov)
Pull request description:
.PHONY does not take patterns (such as print-%) as prerequisites.
Have print-% depend on force and mark force as phony.
This change ensures print-% rule works even when there is a file that matches the target.
