New timespec_get bases:
- TIME_MONOTONIC
- TIME_ACTIVE
- TIME_THREAD_ACTIVE

New functions:
- time_t timegm(struct tm *timeptr); (newly standard, needs visibility outside _NETBSD_SOURCE)
- int timespec_getres(struct timespec *ts, int base);

>How-To-Repeat:
standards inspection
>Fix:
Yes, please!

 Do we want to support TIME_ACTIVE and TIME_THREAD_ACTIVE? These are
 optional.

 Do they map cleanly to CLOCK_PROCESS_CPUTIME_ID and
 CLOCK_THREAD_CPUTIME_ID or is more work needed?
