5624ab0b4f random: stop feeding RNG output back into OpenSSL (fanquake)

Pull request description:

  Now that #17165 has been merged, removing our remaining OpenSSL usage is possible.

  That remaining usage was a call to [`RAND_bytes`](https://www.openssl.org/docs/manmaster/man3/RAND_bytes.html) during the ::SLOW path of [ProcRand](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L616). As well as feeding output from our RNG back into OpenSSL via [`RAND_add`](https://www.openssl.org/docs/manmaster/man3/RAND_add.html) during the ::SLOW and ::SLEEP paths.

  Optimistically tagged for `0.20.0`. Needs discussion, potentially in an upcoming weekly meeting?

  Closes #12530.

Merge #17503: doc: Remove bitness from bitcoin-qt help message and manpage
e161bc74d2 doc: Remove bitness from bitcoin-qt help message and manpage (Wladimir J. van der Laan)

Pull request description:

  Remove the `(64-bit)` from the bitcoin-qt help message.

  Since removing the Windows 32-bit builds, it is no longer information that is often useful for troubleshooting. This never worked for other architectures than x86, and the only 32-bit x86 build left is the Linux one. Linux users tend to know what architecture they are using.

  It also accidentally ends up in the bitcoin-qt manpage (if you happen to be generating them on a x86 machine), which gets checked in. See for example 1bc9988993 (diff-e4b84be382c8ea33b83203ceb8c85296)

random: stop retrieving random bytes from OpenSSL
On the ::SLOW path we would use OpenSSL as an additional source of
random bytes. This commit removes that functionality. Note that this was
always only an additional source, and that we never checked the return
value

RAND_bytes(): https://www.openssl.org/docs/manmaster/man3/RAND_bytes.html

RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf.

random: stop feeding RNG output back into OpenSSL
On the ::SLOW or ::SLEEP paths, we would feed our RNG output back into
OpenSSL using RAND_add. This commit removes that functionality.

RAND_add(): https://www.openssl.org/docs/manmaster/man3/RAND_add.html

RAND_add() mixes the num bytes at buf into the internal state of the
random generator. This function will not normally be needed, as
mentioned above. The randomness argument is an estimate of how much
randomness is contained in buf, in bytes, and should be a number
between zero and num.

Merge #17328: GuessVerificationProgress: cap the ratio to 1
2f5f7d6b13 GuessVerificationProgress: cap the ratio to 1 (darosior)

Pull request description:

  Noticed `getblockchaininfo` would return a `verificationprogress` > 1, especially while generating. This caps the verification progress to `1`.

  Tried to append a check to functional tests but this would pass even without the patch, so it seems better to not add a superfluous check (but this can easily be reproduced by trying to generate blocks in the background and `watch`ing `getblockchainfo`).

b51bae1a5a doc: minor corrections in random.cpp (fanquake)

Pull request description:

  This introduces a new `randomenv` module that queries varies non-cryptographic (and non-RNG) sources of entropy available on the system; things like user IDs, system configuration, time, statistics, CPUID data.

  The idea is that these provide a fallback in scenarios where system entropy is somehow broken (note that if system entropy *fails* we will abort regardless; this is only meant to function as a last resort against undetected failure). It includes some data sources OpenSSL currently uses, and more.

  The separation between random and randomenv is a bit arbitrary, but I felt that all this "non-essential" functionality deserved to be separated from the core random module.

d61f2bb076 Run background seeding periodically instead of unpredictably
* Instead of calling RandAddSeedSleep anytime the scheduler goes
  idle, call its replacement (RandAddSeedPeriodic) just once per
  minute. This has better guarantees of actually being run, and
  helps limit how frequently the dynamic env data is gathered.
* Since this code runs once per minute regardless now, we no
  longer need to keep track of the last time strengthening was
  run; just do it always.
* Make strengthening time context dependent (100 ms at startup,
  10 ms once per minute afterwards).

  - Separates parsing of settings from merging of settings, and deduplicates merging code so it doesn't happen five different places ([GetArg](c459c5f701/src/util/system.cpp (L221-L244)), [GetNetBoolArg](c459c5f701/src/util/system.cpp (L255-L261)), [GetArgs](c459c5f701/src/util/system.cpp (L460-L467)), [IsArgNegated](c459c5f701/src/util/system.cpp (L482-L491)), [GetUnsuitableSectionOnlyArgs](c459c5f701/src/util/system.cpp (L343-L352))) in inconsistent ways.
  - Documents and tests current strange merging behaviors, so they be cleaned up in the future if resulting code simplifications and UX improvements warrant loss of backwards compatibility. The newly documented behaviors are: command line [ignored arguments](69d44f3cc7/src/util/system.cpp (L323-L326)) and [more ignored arguments](69d44f3cc7/src/util/settings.cpp (L67-L72)), and config file [reverse precedence](69d44f3cc7/src/util/settings.cpp (L61-L65)), [inconsistently applied top-level settings](69d44f3cc7/src/util/settings.cpp (L55-L59)), and [zombie values](69d44f3cc7/src/util/settings.cpp (L101-L108)).

  The original motivation for this change was to make it easy to add a new persistent setting source without introducing more bugs and inconsistencies. Two commits building on top of this to add a persistent `-wallet` setting are pretty straightforward and show how the new code can be extended:

  * 70675c3e4975203ad6222ba2b00c83b4e4213793 from #15935 – _Add \<datadir>/settings.json persistent settings storage_
  * 04c80c40df9fc6f4734ba238ea7f65607cf88089 from #15937 – _Add loadwallet and createwallet RPC load_on_startup options_

Merge #17405: wallet: Remove unused boost::this_thread::interruption_point
fad1de66a2 wallet: Remove unused boost::this_thread::interruption_point (MarcoFalke)

Pull request description:

  `BerkeleyEnvironment::Open` is only called from the main thread (init) or an http rpc thread, neither of which can be interrupted, so remove the useless interruption point.

  `BerkeleyEnvironment{}` is only used in tests, which run in a single process/thread, so remove the useless interruption point.

Merge #17354: wallet: Tidy CWallet::SetUsedDestinationState
0b75a7f068 wallet: Reuse existing batch in CWallet::SetUsedDestinationState (João Barbosa)
01f45dd00e wallet: Avoid recursive lock in CWallet::SetUsedDestinationState (João Barbosa)

Pull request description:

  This PR makes 2 distinct changes around `CWallet::SetUsedDestinationState`:
   - 1st the recursive lock is removed and now it requires the lock to be held;
   - 2nd change is to support, in the best case, just a wallet database flush when transaction is added to the wallet.

    Code review ACK 0b75a7f068. Code changes looks fine but PR description should be updated to say what benefits of the change are. I might have missed something, but I didn't see a place where multiple batches were used previously and a single batch was used now. So the main benefit of this change appears to be removing a recursive lock? And maybe moving toward a consistent convention for passing batch instances?

Pull request description:

  Work starter to remove Chain::Lock interface by adding m_last_block_processed_height in CWallet and m_block_height in CMerkleTx to avoid GetDepthInMainChain having to keep a lock . Once this one done, it should ease work to wipe out more cs_main locks from wallet code.

  I think it's ready for a first round of review before to get further.

  - `BlockUntilSyncedToCurrent` : restrain isPotentialTip to isTip because we want to be sure that wallet see BlockDisconnected callbacks if its height differs from the Chain one. It means during a reorg, an RPC could return before the BlockDisconnected callback had been triggered. This could cause a tx that had been included in the disconnected block to be displayed as confirmed, for example.

  ~~- `AbandonTransaction` : in case of conflicted tx (nIndex = -1), we set its m_block_height to the one of conflicting blocks, but if this height is superior to CWallet::m_last_block_processed_height, that means tx isn't conflicted anymore so we return 0 as tx is again unconfirmed~~ After #16624, we instead rely on Confirmation.

  ~~- `AddToWalletIfInvolvingMe`: in case of block disconnected, transactions are added to mempool again, so we need to replace old txn in `mapWallet` with a height set to zero so we remove check on block_hash.IsNull~~ Already done in #16624

7f40528cd5 Deduplicate settings merge code
Get rid of settings merging code in util/system.cpp repeated 5 places,
inconsistently:

- ArgsManagerHelper::GetArg
- ArgsManagerHelper::GetNetBoolArg
- ArgsManager::GetArgs
- ArgsManager::IsArgNegated
- ArgsManager::GetUnsuitableSectionOnlyArgs

Having settings merging code separated from parsing simplifies parsing somewhat
(for example negated values can simply be represented as false values instead
of partially cleared or emply placeholder lists).

Having settings merge happen one place instead of 5 makes it easier to add new
settings sources and harder to introduce new inconsistencies in the way
settings are merged.

This commit does not change behavior in any way.

9dcb952fe5 Add util::Settings struct and helper functions.
Implement merging of settings from different sources (command line and config
file) separately from parsing code in system.cpp, so it is easier to add new
sources.

Document current inconsistent merging behavior without changing it.

This commit only adds new settings code without using it. The next commit calls
the new code to replace existing code in system.cpp.
