Merge #18750: build: optionally skip external warnings
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.

Merge #20130: Wallet: remove db mode string
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.

135afa749c wallet: remove db mode string
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.

generated test cases to files, in a format compatible with the
script_assets_test unit test. A fuzzer for said format is added as well, whose
primary purpose is coverage-based minimization of those dumps.

them in standardness rules. No corresponding `CTxDestination` is added for it,
as that isn't needed until we want wallet integration. The taproot validation flags
are also enabled for mempool transactions, and standardness rules are added
(stack item size limit, no annexes).

173a1d2d3f Expedite removal of tx requests that are no longer needed
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).

242d16477d Change transaction request logic to use txrequest
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.
