more than KBD_BUFFER_SIZE/2, stop reding input (Bug#6571).

returns less than KBD_BUFFER_SIZE/4, resume reding input (Bug#6571).

Don't read more that free slots in kbd_buffer (Bug#6571).

functions.

select on empty input mask.
(init_process): Initialize kbd_is_on_hold to 0.
* buffer.c, cm.c, eval.c, keyboard.c, process.c, term.c, vm-limit.c,
* xdisp.c: Convert function definitions to standard C.

sent to interactive subprocesses.

chars when talking to ttys any more.
(wait_reading_process_output): Output a warning when called in such
a way that it could block without being interruptible.
* xterm.c:
* process.c:
* emacs.c: Use HAVE_SYS_IOCTL_H instead of BSD_SYSTEM as a guard
for including <sys/ioctl.h>.
* sysdep.c (wait_without_blocking): Remove BSD_SYSTEM case, this
code is only used for MSDOS.
* atimer.c (set_alarm): Remove dead code, all USG systems define
POSIX_SIGNALS.

* keyboard.c (input_available_signal, handle_user_signal)
(interrupt_signal): Likewise.
* process.c (sigchld_handler): Likewise.
(create_process): Remove if 0 code. Remove HPUX conditional when
!defined (POSIX_SIGNALS), it cannot be true.
* syssignal.h: Remove USG5_4 and USG conditionals when
!POSIX_SIGNALS, they cannot be true.
timeouts and event sources. This simplifies Gtk+-code a lot, and is needed
for handling GConf death/restart.
* xterm.c: #include xgselect.h.
(x_initialize): Call xgselect_initialize.
* xsettings.c (something_changedCB): C++ comments => C comments.
(init_gconf): Do not deal with any GLib file descriptors, xg_select
does that now.
* gtkutil.c (xg_timer, xg_process_timeouts, xg_start_timer)
(xg_stop_timer, menu_grab_callback_cnt, menu_grab_callback)
(scroll_bar_button_cb): Remove.
(create_menus): C++ comments => C comments. Don't bind grab-notify
event.
(xg_create_scroll_bar): Don't bind button-press-event and
button-release-event.
* process.c: Include xgselect.h if defined (USE_GTK) ||
defined (HAVE_GCONF).
(wait_reading_process_output): Call xg_select for the same condition.
* xgselect.c (xg_select): New function to better integrate with
GLib/Gtk event handling. Needed if GConf daemon dies/restarts.
* xgselect.h: New file, declare xg_select, xgselect_initialize.
* Makefile.in (XOBJ): Add xgselect.o.
* keyboard.h: Declare timer_check.
* keyboard.c (timer_check_2): New function that does what the old
timer_check did.
(timer_check): Call timer_check_2 until -1 or a non-zero time is
returned, i.e. don't return -1 with timers pending.
* process.c: Remove extern declaration of timer_check.
* xmenu.c (x_menu_wait_for_event): Remove code that did a timeout
even if timer_check returned -1.
* gtkutil.c (xg_dialog_response_cb): data is now a struct xg_dialog_data
(pop_down_dialog): Destroy widget (if any), cancel timer and unref
the event loop.
(xg_maybe_add_timer, xg_dialog_run): New functions (bug #4574).
(xg_get_file_name, xg_get_font_name): Call xg_dialog_run (bug #4574).
Destroy the dialog after xg_dialog_run.

* lread.c (intern_c_string): New function.
(defvar_kboard, defvar_lisp, defvar_lisp_nopro, defvar_bool)

* lisp.h (defvar_kboard, defvar_lisp, defvar_lisp_nopro, defvar_bool)
(defvar_int): Update prototypes.
(DEFUN, EXFUN): Support for prototypes is now required.
(intern_c_string): New prototype.
(struct Lisp_Subr): Make symbol_name constant.
* font.c (struct table_entry): Remove unused member. Make NAMES
constant.
(weight_table, slant_table, width_table): Make constant.
* emacs.c (struct standard_args): Make name and longname constant.
* character.h (DEFSYM): Use intern_c_string.
(Fstart_process): Use it to allow Emacs to just associate a pty
with the buffer. See associated change in gdb-mi.el.
(list_processes_1): Deal with no program name.
(start_process_unwind): Use pid == -2 to mean no process.
