d41ed32153 p2p: Avoid InitError when downgrading peers.dat (junderw)
Pull request description:
fixes #24188 (also see https://github.com/bitcoin/bitcoin/pull/22762#issuecomment-951063826)
When downgrading, a peers.dat with a future version that has a minimum
required version larger than the downgraded Bitcoin Core version would cause an InitError.
This commit changes this behavior to overwrite the existing peers.dat with
a new empty one.

fixes #24188
When downgrading, a peers.dat with a future version that has a minimum
required version larger than the downgraded version would cause an InitError.
This commit changes this behavior to overwrite the existing peers.dat with
a new empty one, while creating a backup in peers.dat.bak.
- `m_assumed_chain_state_size` doesn't seem to need to be changed for mainnet.
- No change needed for testnet/signet.

7f3a6a9495 wallet: Add external-signer-support specific error message (Hennadii Stepanov)
Pull request description:
On master (5f44c5c428) an attempt to load an external signer wallet using Bitcoin Core compiled without external signer support fails with the following log messages:

While log messages are good, a message in the GUI window is completely misleading:

9999f891d1 bench: Avoid deprecated use of volatile += (MarcoFalke)
Pull request description:
Deprecated in C++20 according to https://eel.is/c++draft/expr.ass#6 .
```
bench/examples.cpp:16:13: warning: compound assignment with ‘volatile’-qualified left operand is deprecated [-Wvolatile]

```
While C++20 is currently unsupported, I don't see any downside to a minor fixup to an example benchmark. This will also make a hypothetical C++20 patch smaller.

Add a missing const to avoid the C++20 clang **compiler warning**:

This patch also fixes the **compile error** if the first operand is `const`:

Given the low possibility of a reorg reverting the segwit soft fork,
there is no need to check whether segwit is active here. Also,
TestBlockValidity is run on the block template after it has been
created.
Instead of having CBlockIndex's live on the heap, which requires manual
memory management, have them be owned by m_block_index. This means that
they will live and die with BlockManager.
A change to BlockManager::LookupBlockIndex:
- Previously, it was a const member function returning a non-const CBlockIndex*
- Now, there's are const and non-const versions of
BlockManager::LookupBlockIndex returning a CBlockIndex with the same
const-ness as the member function:
(e.g. const CBlockIndex* LookupBlockIndex(...) const)
See next commit for some weirdness that this eliminates.
The range based for-loops are modernize (using auto + destructuring) in
a future commit.

e50a9be154 Remove outdated comment on CFeeRate (Murch)
Pull request description:
This comment described how the constructor of CFeeRate was previously indirectly used to parse fee rate arguments from RPCs. The command line input was actually in sat/vB but due to the use of AmountFromValue() it got converted to BTC/vB which then got rectified in the constructor by creating a CFeeRate from that given value and COIN as the transaction size. Since this usage pattern was removed from the codebase some months ago, the comment is now obsolete.
