CLOCK_MONOTONIC in Timers functions

[Yaakov (Cygwin/X)]

POSIX requires the Timers functions (timer_create, timer_[gs]ettime,
etc.) to also support CLOCK_MONOTONIC if the _POSIX_MONOTONIC_CLOCK
option is available.  I'm willing to take a look at making this happen
when I have the chance.  (Getting gcc 4.5 out is my first priority now.)

I see that timer.cc uses its own WaitForSingleObject calls instead of
using cancelable_wait().  Is there a good reason for this, or could this
be rewritten in terms of the latter?
