to say whether or not the interval tree has been visited (and skip
it when revisited), and the mark bit of the plist field to say
whether or not that interval has been visited (and abort if
revisited); don't try to use the plist mark bit for both
meanings.
* alloc.c (mark_interval_tree): Don't test if the interval tree
has already been visited here; let the MARK_INTERVAL_TREE macro do
that; avoid function call overhead. Mark the interval tree as
having been visited by setting TREE->parent's mark bit.
(MARK_INTERVAL_TREE): If the tree has been visited (according to
I->parent's mark bit), don't call mark_interval_tree.
(gc_sweep): Rebalance the interval trees of those large strings
which are still alive. This also clears the mark bits of those
trees' root intervals' parent fields.
(compact_strings): Rebalance the interval tree of each small
strings which is still alive. This also clears the mark bits of
that tree's root interval's parent field. Since the string has
moved, update the root interval's parent pointer to contain the
new address.
* lisp.h (struct interval): Doc fix; explain the roles of the mark
bits of the parent and plist members.

Use CHECK_OVERLAY instead of signalling a special error.

void *, not void.

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.

* alloc.c (mark_interval_tree): Remove spurious & in front of
function name.
* alloc.c (UNMARK_BALANCE_INTERVALS): Fix to accomodate compilers
other than GCC, which do not allow casts on the LHS of an
assignment.
* alloc.c (mark_object, mark_buffer): Remove some unused
variables.

GC'd; this allows windows and scrollbars can refer to each other
without worrying about dangling pointers.
* xterm.h (struct x_display): vertical_scrollbars and
judge_timestamp members deleted.
(struct scrollbar): Redesigned to be a template for a Lisp_Vector.

VERTICAL_SCROLLBAR_INSIDE_HEIGHT, VERTICAL_SCROLLBAR_MIN_HANDLE):
New macros, to help deal with the lispy structures, and deal with
the graphics.
* frame.h (WINDOW_VERTICAL_SCROLLBAR): Macro deleted.

x_scrollbar_remove, XTset_vertical_scrollbar,
XTcondemn_scrollbars, XTredeem_scrollbar, XTjudge_scrollbars,

signal handler. The original bug is probably gone, the test
wasn't written portably, and it should probably go somewhere else
anyway - say, funcall or eval.
