doing code static analysis (to inform the tool that the function is
a no-return one).
* os_dep.c (GC_linux_stack_base): Remove a duplicate validation of the
length of "stat" file; use signed int type for "i", "buf_offset" and
"len" local variables (since read() may return -1).

* blacklst.c (GC_bl_init_no_interiors): New function (the code
moved from GC_bl_init).
* blacklst.c (GC_bl_init): Invoke GC_bl_init_no_interiors unless
GC_all_interior_pointers mode; remove unnecessarily parameter cast
for GC_scratch_alloc call.
* include/private/gc_priv.h (GC_bl_init): Move the function
declaration to misc.c file.
* misc.c (GC_bl_init_no_interiors): Add a prototype.
* misc.c (GC_set_all_interior_pointers): Allow values other than 0
and 1; allow altering GC_set_all_interior_pointers value even
after GC initialization.
* obj_map.c (GC_initialize_offsets): Clear GC_valid_offsets and
GC_modws_valid_offsets if GC_all_interior_pointers is off.
* misc.c (GC_init): Don't call GC_initialize_offsets() unless
GC_all_interior_pointers mode.

* alloc.c (GC_finish_collection): Remove redundant brackets;
adjust code indentation.
* blacklst.c (GC_add_to_black_list_normal): Simplify expression
(to improve code readability).
* blacklst.c (GC_is_black_listed): Join nested "if" (into a single
conditional expression); initialize "nblocks" just before the loop
beginning.
* misc.c (GC_init): Don't compute initial_heap_sz if GC is already
initialized.
* include/private/gc_priv.h (GC_initialize_offsets): Move the
function declaration to misc.c file.
* obj_map.c (GC_initialize_offsets): Remove offsets_initialized
static variable since the function is called only once.
* tests/middle.c: Include "gc.h" instead of <gc.h>; expand all
tabs to spaces; adjust code indentation; replace the K&R-style
function definition with the ANSI C one.
* tests/smash_test.c: Ditto.
* tests/middle.c (main): Use setter for GC_all_interior_pointers;
adjust printf format specifier (and cast the value passed to).
