(survives_gc_p): New.
(mark_object): Mark objects referenced from glyphs, hash tables,
toolbar date, toolbar window, face caches, menu bar window.
Mark windows specially.
(Fgarbage_collect): Use message3_nolog.
(mark_face_cache): New.
(NSTATICS): Increased to 1024.
(mark_glyph_matrix): New.
Use them instead of malloc, xmalloc, and xfree, for Lisp objects.
Don't set allocating_for_lisp in the callers; let lisp_malloc do it.
(n_interval_blocks, n_float_blocks): New variable.
(n_cons_blocks, n_vectors, n_symbol_blocks): New variable.
(n_marker_blocks, n_string_blocks): New variable.
(init_intervals, make_interval): Set a count variable.
Use lisp_malloc instead of setting allocating_for_lisp.
(init_float, make_float, init_cons, Fcons): Likewise.
(allocate_vectorlike, init_symbol, Fmake_symbol): Likewise
(init_marker, allocate_misc, init_strings): Likewise.
(make_uninit_multibyte_string): Likewise.
(gc_sweep, compact_strings): Decrement the count variables.
(uninterrupt_malloc): Don't store Emacs's hooks
into the old_..._hook variables.
don't mark a marker just cause it is in this list.
(Fgarbage_collect): Discard from all undo-lists
all elements that adjust markers that were not marked.
(make_string_from_bytes): New function.
(compact_strings): Get byte size from size, if size_byte < 0.
(Fmake_string): Use make_uninit_string for single-byte char.
(make_unibyte_string): Mark string as unibyte.
(make_uninit_string): Likewise.
(make_string): Likewise, if size == size in bytes.
(make_pure_string): New arg MULTIBYTE.
(Fpurecopy): Pass new arg to make_pure_string.
Take account of size used by size_byte; store both sizes.
(Fpurecopy): Call make_pure_string the new way.
(compact_strings): Use size_byte field to compute string's size.
(make_uninit_multibyte_string): New function.
(make_uninit_string): Use make_uninit_multibyte_string.
(make_multibyte_string): New function.
(make_unibyte_string): New function.
(make_string): Compute number of chars from the data.
mallopt, struct mallinfo, and mallopt constants.
(BYTES_USED): New macro.
(memory_full, emacs_blocked_free): Replace _bytes_used with BYTES_USED.
(emacs_blocked_malloc): Set sbrk padding value for glibc, as is
done with gmalloc.
(allocate_vectorlike, make_uninit_string):
Prevent using mmap for possible large chunks.
(init_alloc_once): Set trim and mmap malloc parms, when using glibc.
