(XTread_socket): Pass it by reference to XLookupString.
* xterm.c: Clean up some of the caps lock handling:
(x_shift_lock_mask): New variable.
(x_find_modifier_mappings): Set it, based on the modifier mappings.
(x_convert_modifiers): Use x_shift_lock_mask, instead of assuming
that the lock bit always means to shift the character.
(XTread_socket): When handling KeyPress events, don't pass an
XComposeStatus structure along to XLookupString. When handling
MappingNotify events, call XRefreshKeyboardMapping for both
MappingModifier and MappingKeyboard events, not just the latter.
(check_memory_limits): New fn; most code from morecore_with_warning, but
only checks limits, doesn't do any work.
(memory_warnings): Set __after_morecore_hook to check_memory_limits;
don't set __morecore.
Removed elements `nruns' and `face_list'.
LINE_HEIGHT and LINE_WIDTH macros removed.
New struct face with associated typedef FACE declared, along with
accessing macros.
`nruns' and 'face_list' removed. Handle new element `max_ascent'.
(free_frame_glyphs): Don't free nonexistent elements `nruns' and
`face_list'; do free `max_ascent' element.
(make_frame_glyphs): Don't allocate nonexistent elements `nruns'
and `face_list'; do allocate `max_ascent' element.
(update_frame): Replaced use of macro LINE_HEIGHT with element
frame element `pix_height'.
[emacs]: Moved #undef NULL and #include "getpagesize.h" here.
[! emacs]: #include <unistd.h>, <malloc.h>, <string.h>.
(r_alloc_init): Use NIL, not NULL.
(real_morecore): New static variable.
(warnlevel, warn_function, check_memory_limits): Removed.
(obtain): Don't call check_memory_limits.
(obtain, relinquish, r_alloc_sbrk): Use (*real_morecore) in place of sbrk;
it returns 0 for errors, not -1.
(r_alloc_init): Set real_morecore to old value of __morecore.
Don't initialize lim_data or warnlevel, and don't call get_lim_data.
(memory_warnings): Function removed.
(find-file-noselect): Record the file's filenum and devnum.
Notify if any buffer has the same values.
(basic-save-buffer): Save new filenum and devnum.
For file-precious-flag, pass real name as VISIT arg of write-region.
(set-visited-file-name): Likewise.
Clear buffer-file-{number,truename} if now visiting no file.
(memory_warnings): Renamed from malloc_init.
Don't set lim_data or warnlevel. Use start_of_data if start is 0.
[!emacs]: Don't include config.h or lisp.h;
instead, use stddef.h. Define POINTER, SIZE, EXCEEDS_LISP_PTR.
(morecore_with_warning): Use EXCEEDS_LISP_PTR.
(memory_warnings): New function; just set warning data.
Use start_of_data if start is 0.
[!emacs]: Don't include config.h or lisp.h;
instead, use stddef.h. Define POINTER, SIZE, EXCEEDS_LISP_PTR.
[!emacs] (safe_bcopy): Define as macro using memmove.
(r_alloc_free): Clear *ptr.
(r_alloc_init): Renamed from malloc_init. Take no args.
Make it static; declare at top of file.
(r_alloc): Call r_alloc_init, if not initialized yet.
(r_alloc_initialized): Renamed from malloc_initialized; moved to top.
(ROUNDUP): Subtract 1, in case arg is already aligned.
(check_memory_limits): EXCEEDS_LISP_PTR renamed from EXCEEDS_ELISP_PTR.
non-ascii keys.
* keymap.c (access_keymap): Treat bindings for Qt as default
bindings, when new argument T_OK is non-zero.
(get_keyelt, Fdefine_key, Flookup_key): Call access_keymap with
T_OK false.
