Pull request description:
They only make sense for mutexes that are private members. Until cs_main is a private member the negative annotations should be replaced by excluded annotations, which are optional.

Pull request description:
On the way of transit from `RecursiveMutex` to `Mutex` (see #19303) it is crucial to have run-time `AssertLockHeld()` assertion that does _not_ hide compile-time Clang Thread Safety Analysis warnings.
On master (65e4ecabd5b4252154640c7bac38c92a3f3a7018) using `AssertLockHeld()` could hide Clang Thread Safety Analysis warnings, e.g., with the following patch applied:
```diff
--- a/src/txmempool.h
+++ b/src/txmempool.h
@@ -607,7 +607,7 @@ public:
void addUnchecked(const CTxMemPoolEntry& entry, setEntries& setAncestors, bool validFeeEstimate = true) EXCLUSIVE_LOCKS_REQUIRED(cs, cs_main);
void removeRecursive(const CTransaction& tx, MemPoolRemovalReason reason) EXCLUSIVE_LOCKS_REQUIRED(cs);
- void removeForReorg(const CCoinsViewCache* pcoins, unsigned int nMemPoolHeight, int flags) EXCLUSIVE_LOCKS_REQUIRED(cs, cs_main);

void removeConflicts(const CTransaction& tx) EXCLUSIVE_LOCKS_REQUIRED(cs);
void removeForBlock(const std::vector<CTransactionRef>& vtx, unsigned int nBlockHeight) EXCLUSIVE_LOCKS_REQUIRED(cs);
```
Clang compiles the code without any thread safety warnings.
See "Add missed thread safety annotations" commit for the actual thread safety warnings that are fixed in this PR.

77f37f58ad2f349cecb2eda28b415267d3d7d76e doc: update enum naming in developer notes (Jon Atack)
Pull request description:
Per our current doc, the general rule is we follow the C++ Core Guidelines, which for enumerator naming stipulate:
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Renum-caps
```
Don’t use ALL_CAPS for enumerators
Reason: Avoid clashes with macros.
```
but our examples (and often, codebase) are contradictory to it (and perhaps to common usage), which can be confusing when a contributor needs to choose a style to use. This patch:
- updates the enumerator examples to snake_case per CPP Core Guidelines
- clarifies for contributors that in this project enumerators may be snake_case, PascalCase or ALL_CAPS, and to use what seems appropriate.

05f9770c1fa64bd9730cd6e18ec333e0801c00d6 doc: Clarify developer notes about constant naming (Russell Yanofsky)
Pull request description:
I'm pretty sure developer notes were intended to say constants should be upper case and variables should be lower case, but right now they are ambiguous about whether to write:
```c++
extern const int SYMBOL;
```
or:
```c++
extern const int g_symbol;
```
First convention above is better than the second convention because it tells you without having to look anything up that the value of `SYMBOL` won't change at runtime. Also I haven't seen other c++ projects using the second convention.

Pull request description:
Removes some deprecated code from the RPCs:
- signrawtransaction was deprecated in 0.17 and removed in 0.18. A warning message was left in place to advise users to use signrawtransactionwithwallet and signrawtransactionwithkey. That warning can now be removed.
- validateaddress had some functionality deprecated in 0.17 and removed in 0.18. The help text for that functionality was not removed in 0.18 and can be removed now.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

aa929abf8dc022e900755234c857541faeea8239 [docs] Update developer notes to discourage very long lines (John Newbery)
Pull request description:
Mandatory rules on line lengths are bad - there will always be cases where a longer line is more readable than the alternative.
However, very long lines for no good reason _do_ hurt readability. For example, this declaration in validation.h is 274 chars:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams, CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock, ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool) EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
That won't fit on one line without wrapping on my 27" monitor with a comfortable font size. Much easier to read is something like:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams,
CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock,
ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool)
EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
Therefore, _discourage_ (don't forbid) line lengths greater than 100 characters in our developer style guide.
100 chars is somewhat arbitrary. The old standard was 80, but that seems very limiting with modern displays.
