Eliminate 'parameter can be declared as const pointer' cppcheck warnings

(refactoring)

* allchblk.c (free_list_index_of): Add const to pointer argument.
* backgraph.c (is_in_progress): Likewise.
* include/private/gc_priv.h [MSWIN32 || MSWINCE || CYGWIN32]
(GC_is_heap_base): Likewise.
* os_dep.c [USE_WINALLOC && !REDIRECT_MALLOC] (GC_is_malloc_heap_base):
Likewise.
* os_dep.c [MSWIN32 || MSWINCE || CYGWIN32] (GC_is_heap_base):
Likewise.
* os_dep.c [CHECKSUMS && (GWW_VDB || SOFT_VDB) || PROC_VDB]
(GC_or_pages): Likewise.
* finalize.c (GC_grow_table): Add const to entries_ptr argument.
* os_dep.c [USE_WINALLOC && !REDIRECT_MALLOC] (GC_is_malloc_heap_base):
Change while loop to for.
