syscall: clock_systimer() is no longer a system call. It has been replaced with the equivalent, standard interface clock() as the system call.
...
sched/clock: Move the implementation of clock() from libs/libc/time to sched/clock. This is necessary because it calls the (now) internal OS function clock_systimer. clock() is now accessed only via a system call in certain configuratins.
libs/libc/wqueue: Replace calls to clock_systimer() with calls to the equivalent clock().

Rename CONFIG_SCHED_TIMEKEEPING to CONFIG_CLOCK_TIMEKEEPING. That is a better compartmentalized name.

gettimeofday() and settimeofday(): Move gittimeofdady() from sched/clock to libc/time. All remove gettimeofday() from NuttX system calls. It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer tried as a core OS interface.
...
gettimeofday has been decremented in POSIX 2008. settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.

When reading the system timer, don't read a struct timespec, convert it to a fake tick count, then back to a timespec. Remove CLOCK_ACTIVETIME.. it is non-standard, unused, and gets in the way of changes like this
