[svn-r29326] HDFFV-9536: Changed H5check_version() to use libtool shared library version numbers instead of the library version numbers.

bin/h5vers: 
    Changed to copy the shared lib version from lt_vers.am to H5public.h
    (Thanks to Larry who made the changes.)
config/lt_vers.am:
    cosmetic change, nothing material.

src/H5public.h:
    Changed by bin/h5vers.

src/H5.c:
    Changed H5check_version() to use shared library version for compatibility
    checking.

test/tcheck_version.c:
test/testcheck_version.sh.in:
    Changed to use shared library version numbers instead of the HDF5 library
    version numbers for testing.

Tested: tested in Jam (C only), platypus and osx1010dev (enable fortran and C++).
