Modified Files:
        src/sys/kern: kern_condvar.c

Log Message:
Add cv_timedwaitbt, cv_timedwaitbt_sig.

Takes struct bintime maximum delay, and decrements it in place so
that you can use it in a loop in case of spurious wakeup.

Discussed on tech-kern a couple years ago:

https://mail-index.netbsd.org/tech-kern/2015/03/23/msg018557.html

Added a parameter for expressing desired precision -- not currently
interpreted, but intended for a future tickless kernel with a choice
of high-resolution timers.
