(Draft) Fix nasa#1455, High-res timed stream ops
9fe43bc 
Implement high-res timed operations for streams.  This uses an absolute
time via the OS_time_t value, which has a default resolution of 0.1usec
but is configurable.

Fix nasa#1455, High-resolution timed ops
4dfb405 
Add API calls equivalent to existing calls that use an absolute timeout
as opposed to a relative timeout.  The absolute timeout can support
resolution of 0.1 usec in the default configuration.

Internally this primarily affects the underlying call to select().

Note that per the definition of select() in POSIX, it uses a
"struct timeval" which has a resolution of 1 usec.
