  Branch: 7.9

Added support for POSIX style timers using clock_gettime(3). Notably this
fixes nice high resolution thread local cpu time and monotonic real time on
reasonably modern Linux systems.

Also added a few more pike constants about various characteristics of the
cpu/real time interfaces in use.
