config: Move accounting/bandwidth config into the relay module

This commit:
* moves accounting and bandwidth checks into relay_config,
* moves testing options checks into relay_config,
* moves some other minor checks into relay_config,
* exposes some code from src/app/config.c
  (we'll refactor it later in 29211), and
* adds thin wrappers to make the moved code compile.

No functional changes: the moved code is still enabled,
even if the relay module is disabled. (Some of the checks
are re-ordered, so the order of some warnings may change.)

Part of 32213.
