Implementation includes getitimer(), but for now it is static.
Supports ITIMER_REAL only.

May need a header file for ITIMER_*, struct itimerval and the prototypes,
But for now, and the HP NonStop platform this isn't needed, here
<sys/time> has ITIMER_* and struct timeval, and the prototypes can
vo into git-compat-util.h for now (Patch 2/2)
