This removes the code introduced in [#4399](https://github.com/bitcoin/bitcoin/pull/4399)
that attempts to add additional entroy to the OpenSSL PRNG using Windows messages.
Note that this is specific to bitcoin-qt running on Windows.
```
RAND_event() collects the entropy from Windows events such as mouse movements and other user interaction.
It should be called with the iMsg, wParam and lParam arguments of all messages sent to the window procedure.
It will estimate the entropy contained in the event message (if any), and add it to the PRNG.
The program can then process the messages as usual.
```
Besides BIP70, this is the last place we are directly using OpenSSL in the
GUI code. All other OpenSSL usage is in random.cpp.
Note that we are still also doing Windows specific entropy gathering in multiple
other places. Such as [RandAddSeedPerfmon](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L268)
and [RAND_screen()](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L600).
Also note that if RAND_event returns 0 (PRNG has NOT been seeded with enough data), we're
just logging a message and continuing on, which seems less than ideal.
eebcdfa86a [test] rename SegwitVersion1SignatureHash() (John Newbery)
Pull request description:
The function implementing segwit v0 signature hash was originally named
SegwitVersion1SignatureHash() (presumably before segwit v0 was named
segwit v0). Rename it to SegwitV0SignatureHash().
Also rename SignatureHash() to LegacySignatureHash() for disambiguation.

44f7a8d7a7 Disable _FORTIFY_SOURCE when enable-debug (Andrew Chow)
Pull request description:
The `_FORTIFY_SOURCE` macro is enabled by default when hardening is enabled, but it requires optimization in order to be used. Since we disable all optimization with `--enable-debug`, this macro doesn't actually do anything and instead just causes a lot of warnings to be printed. This PR explicitly disables `_FORTIFY_SOURCE` so that these useless warnings aren't printed.

Belts and suspenders: make sure outgoing log messages don't contain
potentially suspicious characters, such as terminal control codes.
This escapes control characters except newline ('\n') in C syntax.
It escapes instead of removes them to still allow for troubleshooting
issues where they accidentally end up in strings.

Prior to this PR, the wallet would not allow the `-rescan` option at
startup if pruning was enabled. This is unnecessarily restrictive. It
should be possible to rescan if pruning is enabled, as long as no blocks
have actually been pruned yet.
Remove the pruning check from WalletInit::ParameterInteraction(). If any
blocks have been pruned, that will be caught in CreateWalletFromFile().
The wallet should not be able to directly access global configuration
from the node. Remove access of "-limitancestorcount" and
"-limitdescendantcount".
fba4baa4fa test: speed up wallet_address_types by whitelisting peers (immediate tx relay) (Sebastian Falbesoner)

32d665c265 test: fix "tx-size-small" errors after default address change (Sebastian Falbesoner)
Pull request description:
Addresses #17043, affects RBF and BIP68 functional tests.
The "tx-size-small" policy rule rejects transactions with a non-witness size of
smaller than 82 bytes (see `src/validation.cpp:MemPoolAccept::PreChecks(...)`),
which corresponds to a transaction with 1 segwit input and 1 P2WPKH output.
Through the default address change, the created test transactions have segwit
inputs now and sending to short scriptPubKeys might violate this rule. By
bumping the dummy scriptPubKey size to 22 bytes (= the size of a P2WPKH
scriptPubKey), on all occurences the problem is solved.
The dummy scriptPubKey has the format:
```21 <21-byte-long string of 'a' or 1s>```

bd3f5a90ec build: remove mingw linker workaround from win gitian descriptor (fanquake)

This workaround was added as part of the switch to gitian building using Ubuntu 14.04 (#6900).
However, it should no longer be required, as we have switched to Bionic (#13171) and that

581c9be0d8 test: speedup wallet_backup by whitelisting peers (immediate tx relay) (Sebastian Falbesoner)
Pull request description:
approaches part of #16613 ("Functional test suite bottlenecks")
The majority of the test time is spent in `sync_mempools()` after sending to
addresses, i.e. the bottleneck is in relaying transactions. By whitelisting the
peers via `-whitelist`, the inventory is transmissioned immediately rather than
on average every 5 seconds, speeding up the test by at least a factor of two:
before:
```
$ time ./wallet_backup.py
real 2m2.523s
user 0m6.093s
sys 0m2.454s
```
with this PR:
```
$ time ./wallet_backup_with_whitelist.py
real 0m36.570s
user 0m5.365s
sys 0m1.696s
```
Note that the test is not deterministic (the `sendtoaddress` RPC in function
`one_send()` is executed with a probability of 50%), hence the times could vary
between individual runs.

15ac916642 doc: Doxygen-friendly descriptor.h comments (Jon Layton)
Pull request description:
Closes#16942.
- Make `Descriptor` overview subtext of `Interface for parsed descriptor objects.`
- Conform to `@param[in, out] argname: Info` in parameter comments. Present in code: feb162d500/src/net_processing.cpp (L1001)
- Remove redundant argument type, `in` vs `out` mentions
- Removed unnecessary backticks around `IsSolvable()`, since Doxygen builds a link to the known function's docs
- Add backticks to refer to `argname`s
`descriptor.cpp` has more documentation, but Doxygen's output doesn't include anything inside unnamed namespaces for some reason. Tried to access them via searchbar.
