[svn-r26276] Merged r26075-80, 86 from features/autotools_rework branch.

Cleans up time functions in the autotools input files. Removed deprecated
gettimeofday() time zone code and configure processing. Also removed
some unused time function configure checks and defines.

Fixes: HDFFV-9083 and HDFFV-9085

Tested on: 32-bit linux, serial and parallel (jam)
           OS X (kite)
           Solaris (emu)
