* alloc.c: Use bool for booleans.

(gc_in_progress, abort_on_gc)
(setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
(dont_register_blocks) [GC_MALLOC_CHECK]:
(suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
(check_string_bytes, make_specified_string, memory_full)
(live_string_p, live_cons_p, live_symbol_p, live_float_p)
(live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
(mark_stack, valid_pointer_p, make_pure_string)
(Fgarbage_collect, survives_gc_p, gc_sweep):
Use bool for booleans, instead of int.
(test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
Remove unused local.
* alloc.c (PURE_POINTER_P):
* lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
* editfns.c (Fformat):
* fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
(Fdo_auto_save):
* fns.c (sweep_weak_table):
* lisp.h (suppress_checking, push_message, survives_gc_p)
(make_pure_string, gc_in_progress, abort_on_gc):
* lread.c (readchar, read1):
* print.c (Fprin1_to_string):
* xdisp.c (push_message):
Use bool for booleans affected directly or indirectly by
alloc.c's changes.
