Pull request description:
This PR:
- uses Qt top-level build facilities without the need to download all-in-one archive
- is based on **BlockMechanic**'s [idea](https://github.com/bitcoin/bitcoin/pull/20600), and is an alternative to #20600
- 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).
Required for adding [Wayland support](https://github.com/bitcoin/bitcoin/issues/19950) on Linux.
---
**Note for reviewers**: With 9046de8a4cbc3899fed9eae084115f423e7ac5bd from #21995 it is easy to verify that there are no changes in the resulted `qt` package archive on the per commit basis. For example, for `HOST=i686-pc-linux-gnu` no commit in this PR introduces any changes.

While limitations on the influence of attackers on addrman already
exist (affected buckets are restricted to a subset based on incoming
IP / network group), there is no reason to permit them to let them
feed us addresses at more than a multiple of the normal network
rate.
This commit introduces a "token bucket" rate limiter for the
processing of addresses in incoming ADDR and ADDRV2 messages.
Every connection gets an associated token bucket. Processing an
address in an ADDR or ADDRV2 message from non-whitelisted peers
consumes a token from the bucket. If the bucket is empty, the
address is ignored (it is not forwarded or processed). The token
counter increases at a rate of 0.1 tokens per second, and will
accrue up to a maximum of 1000 tokens (the maximum we accept in a
single ADDR or ADDRV2). When a GETADDR is sent to a peer, it
immediately gets 1000 additional tokens, as we actively desire many
addresses from such peers (this may temporarily cause the token
count to exceed 1000).
The rate limit of 0.1 addr/s was chosen based on observation of
honest nodes on the network. Activity in general from most nodes
is either 0, or up to a maximum around 0.025 addr/s for recent
Bitcoin Core nodes. A few (self-identified, through subver) crawler
nodes occasionally exceed 0.1 addr/s.
If a ScriptPubKeyMan does not implement Upgrade, then using upgraewallet
will fail unexpectedly. By changing the default to return true, then
this error can be avoided. This is still correct because a successful
upgrade can be that nothing happened.

Pull request description:
Nodes that can reach the I2P network (have set `-i2psam=`) will relay
I2P addresses even without this patch. However, nodes that can't reach
the I2P network will not. This was done as a precaution in
https://github.com/bitcoin/bitcoin/pull/20119 before anybody could
connect to I2P because then, for sure, it would have been useless.
Now, however, we have I2P support and a bunch of I2P nodes, so get all
nodes on the network to relay I2P addresses to help with propagation,
similarly to what we do with Tor addresses.

Negative `nNew` or `nTried` are not possible during normal operation.
So, if we read such values during unserialize, report addrman

Since we now have multiple chainstate objects, only one of them is active at any given
time. An active chainstate has a mempool, but there's no point to others having one.

Pull request description:
_This is an alternative to https://github.com/bitcoin/bitcoin/pull/21514, inspired by https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-815049933. They are mutually exclusive. Just one of them should be merged._
Change assumed ports for I2P to 0 (instead of the default 8333) as this is closer to what actually happens underneath with SAM 3.1 (https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-812632520, https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-816564719).
Don't connect to I2P peers with advertised port != 0 (we don't specify a port to our SAM 3.1 proxy and it always connects to port = 0).
Note, this change:
* Keeps I2P addresses with port != 0 in addrman and relays them to others via P2P gossip. There may be non-bitcoin-core-22.0 peers using SAM 3.2 and for them such addresses may be useful.
* Silently refuses to connect to I2P hosts with port != 0. This is ok for automatically chosen peers from addrman. Not so ok for peers provided via `-addnode` or `-connect` - a user who specifies `foo.b32.i2p:1234` (non zero port) may wonder why "nothing is happening".

2feec3ce31 net: don't bind on 0.0.0.0 if binds are restricted to Tor (Vasil Dimov)
Pull request description:
The semantic of `-bind` is to restrict the binding only to some address.
If not specified, then the user does not care and we bind to `0.0.0.0`.
If specified then we should honor the restriction and bind only to the
specified address.
Before this change, if no `-bind` is given then we would bind to
`0.0.0.0:8333` and to `127.0.0.1:8334` (incoming Tor) which is ok -
the user does not care to restrict the binding.
However, if only `-bind=addr:port=onion` is given (without ordinary
`-bind=`) then we would bind to `addr:port` _and_ to `0.0.0.0:8333` in
addition.
Change the above to not do the additional bind: if only
`-bind=addr:port=onion` is given (without ordinary `-bind=`) then bind
to `addr:port` (only) and consider incoming connections to that as Tor
and do not advertise it. I.e. a Tor-only node.

This PR recommends passing `--disable-external-signer` in the OpenBSD build guide ([as suggested by laanwj](https://github.com/bitcoin/bitcoin/pull/22294#issuecomment-867452411)). The same commit also bumps the OpenBSD version mentioned in the header to 6.9 -- I recently used this document to setup a Bitcoin Core build on 6.9 and the description and all mentioned versions were still valid (before external signer support was enabled by default).
Would be nice if another OpenBSD user could confirm the build error.

This commit fixes 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.
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.
