  signal: Replace BUG_ON()s (2024-07-29 21:57:35 +0200)

----------------------------------------------------------------
Updates for posix timers and related signal code:

* Prepare posix timers selftests for upcoming changes:

	- Check signal behaviour sanity against SIG_IGN

	- Check signal behaviour sanity against timer
	  reprogramm/deletion

	- Check SIGEV_NONE pending expiry read

	- Check interval timer read on a pending SIGNAL

	- Check correct overrun count after signal block/unblock

* Various consolidations:

	- timer get/set

	- signal queue

* Fixes:
	- Correctly read SIGEV_NONE timers

	- Forward expiry while reading expired interval timers
	  with pending signal

	- Don't arm SIGEV_NONE timers

* Various cleanups all over the place

----------------------------------------------------------------
