This patchset allows us to force depends to use system clang.
Previously, #17099 removes our dependency on a specific clang we download from llvm.org, but theuni pointed out that since OSX builds are only ever built with a version of clang that is chosen and "blessed" by Apple, it is more likely that the user will encounter problems if they use their system clang. This patchset forces the user to set `FORCE_USE_SYSTEM_CLANG=1` in order to use their system clang (when they know what they're doing)

0c8461a88e refactor: replace CConnman pointers by references in net_processing.cpp (Sebastian Falbesoner)
Pull request description:
This is a follow-up to the recently merged PR https://github.com/bitcoin/bitcoin/pull/19053, replacing ~~two more types of~~ one more type of pointer (CConnman) by references to increase the code quality -- pointers should either check for `nullptr` or be replaced by references, and the latter strategy seems to be more reasonable.
Again, to keep the review burden managable, the changes are kept simple,
* only tackling `CConnman*` ~~and `BanMan*`~~ pointers
* only within the net_processing module, i.e. no changes that would need adaption in other modules
* keeping the names of the variables as they are

fa8ec00061 rpc: Check that left section is not multiline (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in server. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

6cef3652d1 build: fix -Wformat-security check when compiling with GCC (fanquake)
Pull request description:
GCC expects `-Wformat` to be passed with [`-Wformat-security`](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html), which means
when we test for it in configure it currently fails:
```bash
checking whether C++ compiler accepts -Wformat-security... no
...
configure:15907: checking whether C++ compiler accepts -Wformat-security
configure:15926: g++ -std=c++11 -c -g -O2 -Werror -Wformat-security conftest.cpp >&5
cc1plus: error: '-Wformat-security' ignored without '-Wformat' [-Werror=format-security]
cc1plus: all warnings being treated as errors
```
and never gets added to our CXX flags. Note that Clang does not have this requirement and the check is working correctly there.
The change in this PR is the simple fix, however we might want to consider using something like `-Wformat=2` in future, which in GCC is equivalent to `-Wformat -Wformat-nonliteral -Wformat-security -Wformat-y2k.` and similar [in Clang](https://clang.llvm.org/docs/DiagnosticsReference.html#wformat-2).

Debian GCC ignores -Wformat-security, without -Wformat, which
means when we test for it, it currently fails:
```bash

...

configure:15926: g++ -std=c++11 -c -g -O2 -Werror -Wformat-security conftest.cpp >&5
cc1plus: error: '-Wformat-security' ignored without '-Wformat' [-Werror=format-security]
cc1plus: all warnings being treated as errors
```
Fix this by just combining the -Wformat and -Wformat-security checks
together.

b82f0ca4d5 walletdb: Add MakeBatch function to BerkeleyDatabase and use it (Andrew Chow)
eac9200814 walletdb: Refactor DatabaseBatch abstract class from BerkeleyBatch (Andrew Chow)
Pull request description:
In order to support alternative database systems, we need to have a generic `Batch` class. This PR adds a `DatabaseBatch` abstract class which is implemented by `BerkeleyBatch`. `DatabaseBatch` is now the class that is used by `WalletBatch` to interact with the database. To be able to get the correct type of `DatabaseBatch`, `BerkeleyDatabase` now has a `MakeBatch` function which returns a newly constructed `std::unique_ptr<DatabaseBatch>`. For `BerkeleyDatabase`, that will be `std::unique_ptr<BerkeleyBatch>`.
The `Read`, `Write`, `Erase`, and `Exists` template functions are moved from `BerkeleyBatch`.

fa9f20b647 log: Properly log txs rejected from mempool (MarcoFalke)
Pull request description:
Currently `CheckTxInputs` rejections from the mempool are the only rejections that log directly and unconditionally to debug.log instead of leaving it to the caller. This has multiple issues:
* A rejected RPC transaction will log a redundant failure reason to debug log. All other failures are merely reported to the RPC user.
* A rejected p2p transaction will log the failure twice. Once with the `MEMPOOLREJ` flag, and once unconditionally.
* A rejected orphan transaction will log no failure.
Fix all issues by simply returning the state to the caller, like it is done for all other rejections.
The patch includes whitespace fixups to highlight relevant parts of the codebase and simplify review.

ca3585a483 [net/net processing] check banman pointer before dereferencing (John Newbery)
Pull request description:
Although we currently don't do this, it should be possible to create a
CConnman or PeerLogicValidation without a Banman instance. Therefore
always check that banman exists before dereferencing the pointer.
Also add comments to the m_banman members of CConnman and
PeerLogicValidation to document that these may be nullptr.
