fa80cd3cee test: [refactor] Avoid calling private ProcessMessage() function (MarcoFalke)

Pull request description:

  There is a single unit test, which calls the internal `ProcessMessage` function. This is problematic, because it makes future changes harder, since they will need to carry over this public internal interface each time.

  Also, there is a mixed use of pointers and references in p2p code, where just based on context, a pointer may sometimes assumed to be null, or non-null. This is confusing when reading the code, or making or reading future changes.

  Fix both issues in a series of commits, to:

  * refactor the single unit test to call higher-level functions
  * Make `ProcessMessage` private again
  * Use references instead of implicit non-null pointers, mostly in a scripted-diff

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).
