For minor mode maps, build up a title string,
then let describe_map_tree insert it.
New arg TITLE.
(describe_buffer_bindings): Corresponding changes.

(describe_map_tree): Likewise.
(describe_buffer_bindings): Build suitable list to pass as SHADOW.
(Faccessible_keymaps): New arg PREFIX. Callers changed.

by creating an inheritance structure for each subkeymap
that we create in the inheriting keymap.
(access_keymap): New arg NOINHERIT. All calls changed.
(define_as_prefix): New function.
(Fdefine_key): Use them.
This isn't specific to X, and it allows us to avoid #including
xterm.h in files that don't really have anything to do with X.
* blockinput.h: New file.
* xterm.h (BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT,
UNBLOCK_INPUT_RESIGNAL): These are now in blockinput.h.
(x_input_blocked, x_pending_input): Deleted; there are analogs
in blockinput.h called interrupt_input_blocked and
interrupt_input_pending.
* keyboard.c (interrupt_input_blocked, interrupt_input_pending):
New variables, used by the macros in blockinput.h.
* xterm.c: #include blockinput.h.
(x_input_blocked, x_pending_input): Deleted.
(XTread_socket): Test and set interrupt_input_blocked and
interrupt_input_pending instead of the old variables.
* alloc.c, xfaces.c, xfns.c, xmenu.c, xselect.c, keymap.c:
#include blockinput.h.
* eval.c: #include blockinput.h instead of xterm.h.
* keyboard.c: #include blockinput.h.
(input_poll_signal): Just test
interrupt_input_blocked, instead of testing HAVE_X_WINDOWS and
x_input_blocked.
Block the processing of interrupt input while we're manipulating the
malloc heap.
* alloc.c: (xfree): New function, to make it easy to free things
safely.
(xmalloc, xrealloc): Block X input while doing the deed.
(VALIDATE_LISP_STORAGE, gc_sweep, compact_strings): Use xfree
instead of free.
(uninterrupt_malloc): New function, to install input-blocking
hooks into the GNU malloc routines.
* emacs.c [not SYSTEM_MALLOC] (main): Call uninterrupt_malloc
on startup.
* alloc.c: (make_interval, make_float, Fcons, Fmake_vector,
Fmake_symbol, Fmake_marker, make_uninit_string, Fgarbage_collect):
Use xmalloc instead of malloc; don't bother to check if out of
memory here.
(Fgarbage_collect): Call xrealloc instead of realloc.
* buffer.c: Use xmalloc and xfree instead of malloc and free;
don't bother to check if out of memory here.
(Fget_buffer_create): Put BLOCK_INPUT/UNBLOCK_INPUT pair around
calls to ralloc routines.
* insdel.c: Same.
* lisp.h (xfree): New extern declaration.
* xfaces.c (xfree): Don't #define this to be free; use the
definition in alloc.c.
* dispnew.c, doc.c, doprnt.c, fileio.c, lread.c, term.c, xfns.c,
xmenu.c, xterm.c: Use xfree instead of free.
* hftctl.c: Use xfree and xmalloc instead of free and malloc.
* keymap.c (current_minor_maps): BLOCK_INPUT while calling realloc
and malloc.
* search.c: Since the regexp routines can malloc, BLOCK_INPUT
while runing them. #include blockinput.h.
* sysdep.c: #include blockinput.h. Call xfree and xmalloc instead
of free and malloc. BLOCK_INPUT around routines which we know
will call malloc.
ymakefile (keyboard.o, keymap.o, search.o, sysdep.o, xfaces.o,
xfns.o, xmenu.o, xterm.o, xselect.o, alloc.o, eval.o): Note that
these depend on blockinput.h.
(access_keymap): Handle ints beyond the ASCII range.
(store_in_keymap): Likewise.
(Faccessible_keymaps): Use meta_modifier.
Use vectors for the key sequences.
(Fwhere_is_internal): Use meta_modifier.
(append_key): Always return a vector.
(push_key_description): Handle all modifiers.
Handle large character codes.
(Fkey_description): Move the meta bit, if arg is string.
(Fsingle_key_description): Don't alter integer value.
Make tem long enough.
(Flookup_key): Use meta_modifier as meta-bit if from vector.
(Fdefine_key): Likewise.
Fglobal_key_binding, Fminor_mode_key_binding): Add a new optional
argument ACCEPT_DEFAULT, to control whether this function sees
bindings for t.
(Fwhere_is_internal, describe_map_tree, describe_map_2,
describe_vector): Pass the proper arguments to Flookup_key.
that Flength returns an integer.
* keymap.c: Deal with autoloaded keymaps properly.
(get_keymap_1): Renamed to inner_get_keymap; made
static. New argument AUTOLOAD says to pursue autoloads if
non-zero.
(Fkeymapp, get_keymap, get_keyelt, Flookup_key): Ask get_keymap_1
not to perform autoloads.
(Fdefine_key): Ask get_keymap_1 to perform autoloads. Since
autoloading may GC, remember that we have to GCPRO our local
variables now.
(Fminor_mode_key_binding): Call get_keymap instead of calling
get_keymap_1 with equivalent arguments.
