This, the third part of the high-res-timers code, implements
the POSIX clocks and timers functions.  This code takes
advantage of the prior two parts to allow timers with high
resolution.  Clocks are defined to allow either 1/HZ
resolution (CLOCK_REALTIME & CLOCK_MONOTONIC) or 1 micro 
second resolution (CLOCK_REALTIME_HR & CLOCK_MONOTONIC_HR). 

Most of this code is located in kernel/itime.c with support
bits in several parts of the kernel.  This implementation
defines a timer as a system wide resource with system wide
limits on the number of allocated timers.  This number can
be set at configure time and is defaulted to 3000.  There
are NO other limits on how many timers a process can have.

Test programs, man pages and readme files are available
on the sourceforge high-res-timers site:
