We should eventually request a transaction from all peers that announce
it (assuming we never receive it).
We should prefer requesting from outbound peers over inbound peers.
Enforce the max tx requests in flight, and the eventual expiry of those
requests.

Pull request description:
Add a new wallet flag called `avoid_reuse` which, when enabled, will keep track of when a specific destination has been spent from, and will actively "blacklist" any new UTXOs which send to an already-spent-from destination.
This improves privacy, as a payer could otherwise begin tracking a payee's wallet by regularly peppering a known UTXO with dust outputs, which would then be scooped up and used in payments by the payee, allowing the payer to map out (1) the inputs owned by the payee and (2) the destinations to which the payee is making payments.
This replaces #10386 and together with the (now merged) #12257 it addresses #10065 in full. The concerns raised in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381 are also addressed due to #12257.
~~Note: this builds on top of #15780.~~ (merged)

412987430c Replace OpenDebugLog() with StartLogging() (Anthony Towns)
Pull request description:
Early log messages are dropped on the floor and they'd never make it to the console or debug log. This can be tested by running the test included in this pull request without re-compiling the `bitcoind`.
Fix that by buffering early messages and flushing them as soon as all logging options have been initialized and logging has been started.
This pull request is identical to "Log early messages with -printtoconsole" (#13088) by **ajtowns**, with the following changes:
* Rebased
* Added docstrings for `m_buffering` and `StartLogging`
* Switch `CCriticalSection` (aka `RecursiveMutex`) to just `Mutex` in the last commit
* Added tests

8053e5cdad Remove -mempoolreplacement to prevent needless block prop slowness. (Matt Corallo)
Pull request description:
At this point there is no reasonable excuse to disable opt-in RBF,
and, unlike when this option was added, there are now significant
issues created when disabling it (in the form of compact block
reconstruction failures). Further, it breaks a lot of modern wallet
behavior.
This removes an option that is:
* (a) only useful when a large portion of (other) miners enforce it as well
* (b) is detrimental to everyone (income for miners, RBF notifications for others) who uses it individually otherwise
* (c) is effectively unused
* (d) is often confused with disabling RBF (rather than just remaining stubbornly unaware of it while the rest of the network lets it through)

Pull request description:
~This is based on #14491, review the last 3 commits only.~
Currently, descriptors have an Expand() function which returns public keys and scripts for a specific index of a ranged descriptor. But the private key for a specific index is not given. This allows private keys for specific indices to be derived. This also allows those keys to be imported through the `importmulti` RPC rather than having to provide them separately.

Pull request description:
Make reasoning about dependencies easier by not including unused dependencies.
Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.
As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:
```
$ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
sed 's%^%src/%g' | xargs cat | wc -l
51393
```
Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)

BIP 37 bloom filters have been well-known to be a significant DoS
target for some time. However, in order to provide continuity for
SPV clients relying on it, the NODE_BLOOM service flag was added,
and left as a default, to ensure sufficient nodes exist with such a
flag.
NODE_BLOOM is, at this point, well-established and, as long as
there exist 0.18 nodes with default config (which I'd anticipate
will be true for many years), will be available from some peers. By
that time, the continued slowdown of BIP 37-based filtering will
likely have rendered it useless (though this is already largely the
case). Further, BIP 37 was deliberately never updated to support
witness-based filtering as newer wallets are expected to migrate to
some yet-to-be-network-exposed filters.

Pull request description:
When testing a combination of settings that affect the datadir (e.g. prune, blockfilter, ...) we may need a lot of datadirs.
Bump the maximum number of nodes proactively from 8 to 12, so that caches get populated with 12 node dirs, as opposed to 8.
Also, add an assert that the list of deterministic keys is exactly the number of max nodes (and not more than that.
Also, create the cache faster.

Would change title to something like "Avoid logging transaction decode errors to stderr" instead of "Disallow extended encoding for non-witness transactions." The current title is confusing because this PR isn't really allowing or disallowing anything, just logging the condition differently. "Disallow" also seems to contradict the "Allow exceptions from..." comments in the actual code.
