[svn-r8038] Purpose:

    Bug fix

Description:
    When two property lists are compared, the H5Pequal routine was just
comparing the raw information for the property values.  This causes problems
when the raw information contains pointers to other information.

Solution:
    Allow a 'compare' callback to be registered for properties, so that a user
application get perform the comparison itself, allowing for "deep" compares of
the property value.
    This was exported to the H5Pregister & H5Pinsert routines in the development
branch, but not the release branch.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    h5committest
