Subject: [PATCH v2 09/20] dyndbg: constify ddebug_apply_class_bitmap args

ddebug_apply_class_bitmap() does not alter its 2 bitmap args, make
this guarantee in the interface.

NOTE: the bitmap is also available in the dcp arg, but the 2 vars
serve a 2nd purpose; the CLASS_TYPE callers use them to translate
levels into their underlying disjoint representation.
