[svn-r9115] Purpose:
feature

Description:
Another revamp of the test interface.
TestInit: is used to register Test Program name, test program specific
   Usage and option parsing routines.
TestUsage: will invoke extra usage routine if provided.
TestParseCmdLine: will invoke extra option parsing routine if provided.
GetTestSummary() and GetTestCleanup() replaces the previous Summary and
CleanUp arguments of TestParseCmdLine.

test/testhdf5, test/ttsafe.c, testpar/t_mpi.c, testpar/testphdf5.c:
   All have been updated to use the new Test Routines.

testpar/t_mpi.c:
   Also a fix of a compiler optimization bug when pgcc in Linux is
   used to compile it.  Changed buf[] and expected to unsigned char
   type to avoid a bug that failed to do sign-extension.

Platforms tested:
"h5committested"
Also tested thread-safe option in eirene.
