[svn-r356] Changes since 19980421

----------------------

./bin/release
./src/H5.c
./src/H5private.h
./src/H5public.h
./src/H5Fpublic.h
        Changed the version number constants to names that begin with
        H5_VERS_ and added macros that check that the version numbers
        in the include files match the version number of the library.

./MANIFEST
./html/H5.user.html
./html/Version.html    [NEW]
./html/version.obj     [NEW]
./html/version.gif     [NEW]
        Documented version numbers and the macros, constants, and
        functions associated with them.

./bin/versinc
        A perl script that increments the minor version number and
        sets the patch level back to zero.  This is intended to be
        invoked from the top of the source tree by a cvs commit
        anywhere in the source tree. Quincey?

./src/H5O.c
./src/H5Oprivate.h
        Added H5O_count() to count the number of object header
        messages of a particular type.  Quincey needs this for the
        attribute package.

./test/dsets.c
        Fixed warnings. Enabled the small strip-mine buffer test.

./config/linux
        Added optimizations for the Pentium-Pro for production mode.
