Specify that internal allocations failure is unlikely

(refactoring)

* finalize.c [!GC_NO_FINALIZATION]
(GC_register_disappearing_link_inner): Assume failure of allocation
(resulting in NULL or GC_oom_fn call) is unlikely.
* malloc.c [DBG_HDRS_ALL || GC_GCJ_SUPPORT || !GC_NO_FINALIZATION]
(GC_generic_malloc_inner_ignore_off_page): Likewise.
* malloc.c (GC_generic_malloc): Likewise.
* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER] (calloc,
strdup, strndup): Likewise.
* mallocx.c (GC_realloc, GC_memalign, GC_strdup, GC_strndup): Likewise.
* mallocx.c [GC_REQUIRE_WCSDUP] (GC_wcsdup): Likewise.
* specific.c [USE_CUSTOM_SPECIFIC] (GC_setspecific): Likewise.
* typd_mlc.c (GC_make_sequence_descriptor, GC_make_descriptor):
Likewise.
* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER] (calloc):
Expect that lb and n are not greater than GC_SQRT_SIZE_MAX.
* typd_mlc.c (GC_calloc_explicitly_typed): Likewise.
* typd_mlc.c (GC_add_ext_descriptor): Assume that resizing of
GC_ext_descriptors[] is rare.
* typd_mlc.c (GC_calloc_explicitly_typed): Do not call
GC_make_array_descriptor() if n * lb > GC_SIZE_MAX.
* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER && !strndup]
(strndup): Expect that len is not greater than size.
* mallocx.c (GC_strndup): Likewise.
* typd_mlc.c (GC_make_sequence_descriptor): Reformat code.
