[svn-r7434] Purpose:

    Bug Fix and code cleanup

Description:
    Correct error in H5T_detect_class that was causing nested compound datatypes
with to not detect the datatype class of fields correctly, which caused errors
with fill-values, variable-length datatypes and chunks later on.

    Return the rank of the array datatype from H5Tget_array_dims(), like
H5Sget_dims().

    Lots of cleanups to datatype code, to make the handling of arrays, compound
types, variable-length strings and sequences and enumerated types more
consistent and robust.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    h5committest
