b448b01494test: add a mocked Sock that allows inspecting what has been Send() to it (Vasil Dimov)f1864148c4test: put the generic parts from StaticContentsSock into a separate class (Vasil Dimov)4b58d55878test: move the implementation of StaticContentsSock to .cpp (Vasil Dimov) Pull request description: 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()` methods can be controlled after the object is created. To achieve that, the caller/creator of `DynSock` provides to its constructor two pipes (FIFOs) - recv-pipe and send-pipe. Whatever data is written to recv-pipe is later received by `DynSock::Recv()` method and whatever data is written to the socket using `DynSock::Send()` can later be found in the send-pipe. For convenience there are also two methods to send and receive `CNetMessage`s. --- This is used in https://github.com/bitcoin/bitcoin/pull/26812 (first two commits from that PR). Extracting as a separate PR suggested here: https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1619152037.

Test library
This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).
Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.
The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common
defines the common test setup for all test binaries. The test binaries will handle the global state when they
instantiate the BasicTestingSetup (or one of its derived classes).
