Yo All!

timestamp_t is now gone.  All replaced by timespec_t.

timestamp_t was never big enough to hold UNIX time to the nanosecond.
This led to all sorts of problems with precision and numerical stability.

timespec_t, at least on 64 bit systems, is good for the 2038 UNIX time
overflow event.  Not much we can do for 32-bit systems until the
system calls get fixed.

timespec_t is easy to work with, as long as you use the macros in
timespec.h.  A few more places in the code can be converted to use the
macros.

Few regressions changed, and those for the better.
