[svn-r21517] - Added checks for clock_gettime() to configure.in.

Tested on Linux, FreeBSD, Solaris, MacOSX to ensure they are found correctly and everything builds.  No code currently relys on clock_gettime().

- Brought Windows and VMS H5pubconf.h files into sync with the Linux file.

Tested on Windows.  Ray will test on VMS when this is pushed to the 1.8.x branch.
