fa1f6f237d net: Send post-verack handshake messages at most once (MarcoFalke)
Pull request description:
There is no need to send `SENDHEADERS` and `SENDCMPCT` messages as a reply to each `VERACK` that is received. For alive checks, a `PING`/`PONG` can be used.

Pull request description:
This replaces the transaction request logic with an encapsulated class that maintains all the state surrounding it. By keeping it stand alone, it can be easily tested (using included unit tests and fuzz tests).
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight already, we still want to request it from them. The cap is replaced with a rule that announcements from such overloaded peers get an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available).
* The limit of 100000 tracked announcements is reduced to 5000; this was excessive. This can be bypassed using the PF_RELAY permission (to accommodate locally dumping a batch of many transactions).
This replaces #19184, rebased on #18044 and with many small changes.

ba8950ee01 build: optionally skip external warnings (Vasil Dimov)
Pull request description:
Add an option to `./configure` to suppress compilation warnings from
external headers. The option is off by default (no change in behavior,
show warnings from external headers).
This option is useful if e.g. Boost or Qt is installed outside of
`/usr/include` (warnings from headers in `/usr/include` are already
suppressed by default) and those warnings stand in the way of compiling
Bitcoin Core with `-Werror[=...]` or they just clutter the build output
too much and make our own warnings hard to spot.
`-isystem /usr/include` bricks GCC's `#include_next`, so we use
`-idirafter` instead. This way we don't have to treat `/usr/include`
specially.

135afa749c wallet: remove db mode string (Ivan Metlushko)
Pull request description:
This is a [follow-up](https://github.com/bitcoin/bitcoin/pull/19077#discussion_r500261927) for #19077
This PR simplifies DB interface by removing mode string from `WalletDatabase` and `WalletBatch`.
The mode string was used to determine two flags for the instantiation of db connection:
1) read-only flag. Never used on connection level. And on batch level Is only used within `BerkeleyDatabase::Rewrite` where it's replaced with bool flag.
2) create flag. Is not required as we always check `require_existing` & `require_create` flags in `MakeDatabase()` before creating actual database instance. So we can safely default to always creating database if it doesn't exist yet.

Pull request description:
This PR enables one more of the non-wallet functional tests (p2p_leak_tx.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078. It also adds missing p2p_lock acquires that need to be held while modifying internal p2p Interface state (in this case the `last_message` dictionary) to avoid data races.

We never need to open database in read-only mode as it's controlled
separately for every batch.
Also we can safely create database if it doesn't exist already
because require_existing option is verified in MakeDatabase
before creating a new WalletDatabase instance.
Whenever a transaction is added to the mempool or orphan pool, both
its txid and wtxid are considered AlreadyHave, and thus will eventually
be removed from m_txrequest.
The same is true for hashes added to the reject filter, but note that sometimes
only the wtxid is added (in which case only the wtxid can be removed from
m_txrequest).
Maintaining up to 100000 INVs per peer is excessive, as that is far more
than fits in a typical mempool.
Also disable the "overload" penalty for PF_RELAY peers.
This removes most transaction request logic from net_processing, and
replaces it with calls to a global TxRequestTracker object.
The major changes are:
* Announcements from outbound (and whitelisted) peers are now always
preferred over those from inbound peers. This used to be the case for the
first request (by delaying the first request from inbound peers), and
a bias afters. The 2s delay for requests from inbound peers still exists,
but after that, if viable outbound peers remain for any given transaction,
they will always be tried first.
* No more hard cap of 100 in flight transactions per peer, as there is less
need for it (memory usage is linear in the number of announcements, but
independent from the number in flight, and CPU usage isn't affected by it).
Furthermore, if only one peer announces a transaction, and it has over 100
in flight and requestable already, we still want to request it from them.
The cap is replaced with an additional 2s delay (possibly combined with the
existing 2s delays for inbound connections, and for txid peers when wtxid
peers are available).
Includes functional tests written by Marco Falke and Antoine Riard.
This adds a fuzz test that reimplements a naive reimplementation of
TxRequestTracker (with up to 16 fixed peers and 16 fixed txhashes),
and compares the real implementation against it.
This adds a new module (unused for now) which defines TxRequestTracker, a data
structure that maintains all information about transaction requests, and coordinates
requests.
