screammandClaude Fable 5.1 5471844c5d feat(libkernel): add setitimer on the alarm timer ...

PS5MC (PPSA99420) imports setitimer (hPWDGx8ioXQ, aerolib) at registry
index 472, after tcsetpgrp and before getitimer. Predicted stop:
"FAIL: unresolved ELF import hPWDGx8ioXQ from libkernel.prx".

setitimer follows FreeBSD 11.4 kern_time.c (8c639945) sys_setitimer and
kern_setitimer: EINVAL for an unknown timer and for an itimerfix failure
or more than INT32_MAX / 2 seconds; a zero value clears the interval and
disarms; a null value reads the timer, EFAULT when the output is null too.
ITIMER_REAL shares the alarm state, now with an interval that re-arms it
as realitexpire does; alarm clears it, as FreeBSD's alarm.c does.

Guest SIGALRM handlers are not run, so an expiry with a handler, or with
SIGALRM blocked (signals are never left pending), throws naming the
interval; SIG_IGN drops it and the default disposition exits with 142,
as alarm already did. Intervals below 1 ms throw (itimerfix rounds them
to tick / 16 and the console's hz is unknown). ITIMER_VIRTUAL and
ITIMER_PROF throw when armed and read and disarm as zero.
