src/sys/sys: signalvar.h
Log Message:
- Untangle spawn_return by splitting it up to sub-functions.
- Merge the eventswitch parent notification code which was copied in two
places (eventswitchchild)
- Fix bugs in the eventswitch parent notification code:
1. p_slflags should be accessed holding both proc_lock and p->p_lock
2. p->p_opptr can be NULL if the parent was PSL_CHTRACED and exited.
Fixes random crashes the posix_spawn_kill_spawner unit test which tried
to dereference a NULL pptr.
