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 C99-like or HelenOS-specific
interfaces to libc.

Specifically, use of sys/time.h, struct timeval, suseconds_t and
gettimeofday is replaced by time.h (C99), struct timespec (C99),
usec_t (HelenOS) and getuptime / getrealtime (HelenOS).
