Fix GC_register_disclaim_proc for leak-finding mode
Issue #252 (bdwgc).
This makes the behavior of GC_register_disclaim_proc() and
GC_finalized_malloc() somewhat consistent with
GC_register_disappearing_link() and GC_register_finalizer() when
find-leak is on. The documentation is updated accordingly.
* fnlz_mlc.c [ENABLE_DISCLAIM] (GC_finalized_disclaim): Add assertion
that GC_find_leak is off.
* fnlz_mlc.c [ENABLE_DISCLAIM] (GC_register_disclaim_proc): Do not
assign ok_disclaim_proc, ok_mark_unconditionally fields if GC_find_leak.
* include/gc_disclaim.h (GC_register_disclaim_proc,
GC_finalized_malloc): Refine comment about leak-find mode and GC_free
invocation.
