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