[svn-r26413] Merge of r26276 from trunk.

Cleans up time functions in the autotools input files.

- Lumps all the time functionality together in configure.ac.
  This was previously more spread out due to Solaris issues
  with the ordering of certain checks.

- Removes processing that handles __tm_gmtoff members of struct
  tm. (libc-4)

- Removes BSDgettimeofday(). (IRIX 5.3)

- Removes timezone struct processing in gettimeofday(). (considered
  harmful)

Fixes: HDFFV-9083 and HDFFV-9085

Tested on: h5committest
           OS X (quail)
           Solaris (emu)

+    - Removed obsolete time functionality from configure and C library
+
+      The library contained some residual functionality from obsolete
+      time zone handling code. This has been removed and the configure
+      checks for the time functions have been cleaned up.

+      Note that the HDF5 library stores timestamps in a platform-independent
+      manner, so old files can still be read. This only affects convering
+      system time to HDF5 timestamps.
+
+      The library currently uses the tm_gmtoff member of the tm struct
+      (preferred, if available) or the timezone global variable to
+      construct HDF5 timestamps.
