Rename cl-bind-* to cl--bind-*.

adjust comment accordingly.
* src/alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
to denote vector blocks. Adjust users (live_vector_p,
mark_maybe_pointer, valid_lisp_object_p) accordingly.
(COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
(VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

(init_alloc_once): Add call to init_vectors.
* doc/lispref/internals.text (Garbage Collection): Document new
vector management code and vectorlike_header structure.
Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
would mishandle a string argument "Xc" if X was a multibyte
character of length 2: it would truncate after X's first byte
rather than including all of X.
* configure.in (PAXCTL): Check for paxctl.
* src/Makefile.in (PAXCTL): Define.
(temacs$(EXEEXT)): Disable memory randomization for the temacs
binary via PaX flags if the paxctl utility is available.

Restore PaX flags to their default.

* src/xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
(note_mode_line_or_margin_highlight): If there is no help echo,
use mode-line-default-help-echo. Handle the case where the mouse
position is past the end of the mode line string.

terminology for consistency.
* src/keyboard.c: Export real-this-command to Elisp.
(syms_of_keyboard): Rename real_this_command to Vreal_this_command
and DEFVAR it. Update all users.
Fixes: debbugs:11506
bitfields where appropriate, remove unused fields.
* window.h (struct window): Remove unused 'last_mark_x' and
'last_mark_y' fields. Rename 'mini_p' field to 'mini',
change it's type from Lisp_Object to bitfield.
Change type of 'force_start', 'optional_new_start',
'last_had_star', 'update_mode_line' and 'start_at_line_beg'
fields from Lisp_Object to bitfield. Adjust users accordingly.
* lisp/image.el: For clarity, call imagemagick-register-types at
top-level, rather than relying on a custom :initialize.
(imagemagick-types-enable): New option.
(imagemagick-register-types): Respect imagemagick-types-inhibit.
If disabling support, remove elements altogether rather
than using an impossible regexp.
(imagemagick-types-inhibit): Give it the default init function.
* src/image.c (Fimagemagick_types): Doc fix.
* etc/NEWS: Mention this.
Fixes: debbugs:11557
* xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
[HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
Use 'float' consistently, rather than 'float' in most places
and 'double' in a couple of places.
* etc/PROBLEMS: Remove obsolete '#define static' cruft.
* lwlib/xlwmenu.c [emacs]: Include "bitmaps/gray.xbm".
(gray_bitmap_width, gray_bitmap_height, gray_bitmap_bits) [!emacs]:
Remove; all uses replaced with definiens.
* src/s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
This #undef was "temporary" in 2000; it is no longer needed
now that '#define static' has gone away.
* src/xfns.c, src/xterm.h (gray_bitmap_width, gray_bitmap_height)
(gray_bitmap_bits): Remove; no longer needed.
All uses replaced with definiens.
* src/xterm.c: Include "bitmaps/gray.xbm".
The following changes affect the code only when profiling.
* dispnew.c (__executable_start): Rename from safe_bcopy.
Define only on platforms that need it.
* emacs.c: Include <sys/gmon.h> when profiling.
(_mcleanup): Remove decl, since <sys/gmon.h> does it now.
(__executable_start): Remove decl, since lisp.h does it now.
(safe_bcopy): Remove decl; no longer has that name.
(main): Coalesce #if into single bit of code, for simplicity.
Cast pointers to uintptr_t, since standard libraries want integers
and not pointers.
* lisp.h (__executable_start): New decl.
src/xdisp.c (handle_stop): Detect whether we have overlay strings
loaded by testing it->current.overlay_string_index to be
non-negative, instead of checking whether n_overlay_strings is
positive.
* buffer.c (Fmove_overlay): Reinstate the earlier fix for
Bug#9642, but explicitly check that the buffer the overlay would
be moved to is live and rearrange lines to make sure that errors
will not put the overlay in an inconsistent state.
(Fdelete_overlay): Cosmetics.
src/search.c (search_buffer): Remove calls to
r_alloc_inhibit_buffer_relocation, as it is now called by
maybe_unify_char, which was the cause of relocation of buffer text
in bug#11519.
src/w32term.c (my_bring_window_to_top): New function.
(x_raise_frame): Use handle returned by DeferWindowPos, which
could be different from the original one. Call
my_bring_window_to_top instead of my_set_foreground_window.
src/w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
by calling BringWindowToTop.
src/w32term.h (WM_EMACS_BRINGTOTOP): New message.
(WM_EMACS_END): Increase by one.
src/charset.c (maybe_unify_char): Inhibit relocation of buffer text
for the duration of call to load_charset, to avoid problems with
callers of maybe_unify_char that access buffer text through C
pointers.
src/ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
decrement the inhibition flag, instead of just setting or
resetting it.
Fixes: debbugs:11519
The code was computing A - B, where A and B are pointers, and B is
random garbage. This can lead to core dumps on platforms that
have special pointer registers, and it also leads to core dumps on
x86-64 when compiled with gcc -ftrapv. The fix is to compute
A - B only when B is initialized properly.
* coding.c (coding_set_source, coding_set_destination): Return void.
(coding_change_source, coding_change_destinations): New functions,
with the old behaviors of coding_set_source and coding_set_destination.
All callers that need an offset changed to use these new functions.
