[svn-r15485] Purpose: Allow library to shut down properly when objects have reference count
> 1.
Description: Added a new field 'app_count' to H5I_id_info_t struct, to track
the reference count on an id due to the application. the old 'count' field
tracks the total. Generally any id visible to the application gets placed
in app_count. Added app_ref boolean parameter to H5I_inc_ref, H5I_dec_ref,
H5I_register, H5I_clear_type, and a few other functions, to specify whether
the operation(s) being performed on the id(s) are due to the application
(TRUE) or not (FALSE). Test added for this case.
Tested: kagiso, smirom, linew (h5committest)
