hdf5

[svn-r19941] Purpose:
Moved the two shape same tests from testphdf5 to a separated executables,
named t_shapesame. The shape same tests runs too long for testphdf5.
In a separated executalbe, it will be easier to separate any errors in
testphdf5 sub-tests from the shape same tests.

t_shapesame.c:
   Contains the shape same tests (cloned from t_rank_projection.c) plus
   a duplicate of "testphdf5.c" for now. After verifying it is correct, more
   cleanup is needed.
testphdf5.c:
   Removed the two shape same tests (chsssdrpio & cbhsssdrpio).
Makefile.am:
Makefile.in:
   Added t_shapesame as a new test executable.
   Removed t_rank_projections.c from part of testphdf5.
testph5.sh.in:
   Temporary added the "t_shapesame -p" test for testing shape same tests
   with MPIO-Posix VFD.

Tested: h5committested, plus serial jam.
