chrg6 dd78132e6d Tell a crash on the RTSS thread as the game's own call of RivaTuner's library, and skip the restore there. ...

main.c foreign_hook matches "hook", so a crash in RTSSHooks64.dll got the line that the library is not part of the
game and that a recording, overlay or capture program put it there, also when the game's own thread that sets the
frame limit (rtss_limit.c's "rtss" worker) had loaded and called it. The one RTSS crash on record (issue #231)
faulted in ntdll on that thread, where no note applied. And the crash handler then called rtss_limit_restore from
that thread, whose own lock it holds (SRW locks are not recursive), so the restore's trylocks spent a second.

The platform layer keeps the name a thread was made with in the thread itself (plat_thread_name, copied at its
start: a detached thread's struct may go before it ends). main.c crash_module_note picks the note: on the "rtss"
thread, whatever the module, the line says the fault is in the game's calls of RTSS's library or around them and
that rtss = 0 keeps the game from calling it; on other threads RTSSHooks64.dll stays foreign, as it is RTSS's
overlay there. The restore is skipped on the rtss thread. rtss_limit.c is unchanged: the thread is known by the name
it is spawned with. Crash text only, besides the skipped restore.

Not reproduced before the change. tests/foreign_hook_check.py checks the note's choice (RTSSHooks64.dll and ntdll on
the RTSS thread: the RTSS note; RTSSHooks64.dll elsewhere: foreign; a driver: none), and tests/crash_stack_check.py
that the crash report reads the faulting thread's name. They, thread_end_check, fatal_exit_check and the compile
checks of every runtime file pass.
