Message:

Get rid of sys/time.h

This commit moves the POSIX-like time functionality from libc's
sys/time.h to libposix and introduces C11-like or HelenOS-specific
interfaces to libc.

Specifically, use of sys/time.h, struct timeval, suseconds_t and
gettimeofday is replaced by time.h (C11), struct timespec (C11), usec_t
(HelenOS) and getuptime / getrealtime (HelenOS).

Also attempt to fix the implementation of clock() to return microseconds
(clocks) rather than processor cycles and move it to libc.
