[svn-r10752] Purpose:

    Added new H5Error APIs.
Description:
    Added C entries for
	H5Eregister_class         H5Eunregister_class
	H5Eget_class_name         H5auto_is_stack
	H5Ecreate_msg             H5Eget_msg
	H5Eclose_msg
	H5Eget_num                H5Epop
	H5Eget_current_stack      H5Eclose_stack
    Still missing -- 6 APIs that match existing APIs except that they
    include a 'stack' parameter.  Those APIs will be added shortly.
Platforms tested:
    Firefox
