The pair tests that pass go in tests_good, and each runs twice: through
the built-in server's relay and P2P. pair_known_failures lists the ones
that fail in only one mode. A P2P test that needs a loopback address
the machine lacks (macOS has only 127.0.0.1) is skipped with a warning,
and the run fails at the end with the command that adds it. The macOS
CI runners add 127.0.0.2. Each run gets a random port offset.

--instance=N sets PPSSPP_ID, so each instance gets its own 127.0.0.N address
and MAC; headless left it at 0, which made its address 127.0.0.0.
--realtime keeps emulated time from running ahead of the wall clock. Only
display flips paced headless, and a test that doesn't draw never flips, so
two instances waiting for each other over the network timed out at once.
--adhoc-server runs the built-in ad hoc server.
Tools/adhoc_multi.py runs a multi-console pspautotest (X_host, X_client,
X_client2, ...) on one instance per role, with the built-in server or, with
--relay, a local aemu_postoffice in relay mode.
