Use Clang's native code coverage workflow

Use Clang's native code coverage compilation, gathering and result reporting if the compiler is Clang, as described in https://clang.llvm.org/docs/SourceBasedCodeCoverage.html. Also use an option for enabling coverage instead of a build...

test: add mocked Sock that can read/write custom data and/or CNetMessages

16

Put the generic parts from `StaticContentsSock` into a separate class `ZeroSock` so that they can be reused in other mocked `Sock` implementations. Add a new `DynSock` whose `Recv()` and `Send()`...

Split CConnman

48

Currently `CConnman` is a mixture of: * low level socket handling, e.g. send, recv, poll, bind, listen, connect, and * higher level logic that is specific to the Bitcoin P2P...

Split socket handling out of CConnman

3

### Please describe the feature you'd like to see added. Split `CConnman` in two pieces: * protocol agnostic low level socket and connection handler and * bitcoin-p2p protocol specific handler....

Prioritize processing of peers based on their CPU usage

1

### Please describe the feature you'd like to see added. Currently, we process messages to/from all peers in a loop where every peer is processed once (has the same weight)....

`program_invocation_name` is defined by the system headers only on Linux, or at least it is not available on FreeBSD. Thus, maintain own global variable that contains the program name.

Listen on random port by default (not 8333)

15

### Please describe the feature you'd like to see added. Connections to port 8333 can be recognized right away as Bitcoin P2P connections. While it is still possible to recognize...

build: enable libc++ hardening in debug builds

27

When compiling with libc++ in debug mode, then enable full libc++ hardening. Inspired by https://github.com/bitcoin/bitcoin/issues/31272#issuecomment-2518700939 --- Note that `libstdc++`'s `_GLIBCXX_ASSERTIONS` (aka light debug mode) is [enabled by default](https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros.html) when compiling...
