[svn-r6395] Purpose:

    Code cleanup.

Description:
    Break up the ~9350 line H5T.c module into smaller pieces, which contain
    code for a particular feature or support for a datatype class.

    This should make the "main" H5T code (still in H5T.c) easier to support,
    as well as removing some of the "minor" routines from the user applications
    which don't use them (my rough estimates show about 4% reduction (~30K on
    a FreeBSD machine) in optimized, staticly-linked binaries for very simple
    programs)

Platforms tested:
    Tested h5committest {arabica (fortran), eirene (fortran, C++)
	modi4 (parallel, fortran)}

    FreeBSD 4.7 (sleipnir)

Misc. update:
    Update MANIFEST
