Fixes Bug#15880.
If USE_LSB_TAG, arrange for the representation of Qnil to be zero so
that NILP (x) is equivalent to testing whether x is 0 at the
machine level. The overall effects of this and the previous patch
shrink the size of the text segment by 2.3% and speeds up
compilation of all the .elc files by about 0.5% on my platform,
which is Fedora 20 x86-64.
* lib-src/make-docfile.c (compare_globals):
* src/lisp.h (lisp_h_XPNTR, lisp_h_XSYMBOL, lisp_h_XUNTAG)
(make_lisp_symbol) [USE_LSB_TAG]:
Symbols now tag the difference from lispsym, not the pointer.
(lisp_h_XUNTAGBASE, TAG_SYMPTR): New macros.
(Lisp_Int0, Lisp_Int1, Lisp_Symbol, Lisp_Misc, Lisp_String, Lisp_Cons):
Renumber so that Lisp_Symbol is 0, so that Qnil is zero.
(XSYMBOL): New forward decl.
(XUNTAGBASE): New function.
(XUNTAG): Use it.
Fixes Bug#15880.
This patch also makes Q constants (e.g., Qnil) constant addresses
from the C point of view.
* make-docfile.c: Revamp to generate table of symbols, too.
Include <stdbool.h>.
(xstrdup): New function.
(main): Don't process the same file twice.
(SYMBOL): New constant in enum global_type.
(struct symbol): Turn 'value' member into a union, either v.value
for int or v.svalue for string. All uses changed.
(add_global): New arg svalue, which overrides value, so that globals
can have a string value.
(close_emacs_global): New arg num_symbols; all uses changed.
Output lispsym decl.
(write_globals): Output symbol globals too. Output more
ATTRIBUTE_CONST, now that Qnil etc. are C constants.
Output defsym_name table.
(scan_c_file): Move most of guts into ...
(scan_c_stream): ... new function. Scan for DEFSYMs and
record symbols found. Don't read past EOF if file doesn't
end in newline.
* alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle:
* casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c:
* composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c:

* frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c:
* image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c:
* macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m:
* nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c:
* search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c:
* window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c:
* xselect.c, xsettings.c, xterm.c:
Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs).
These names are now defined automatically by make-docfile.
* alloc.c (init_symbol): New function.
(Fmake_symbol): Use it.
(c_symbol_p): New function.
(valid_lisp_object_p, purecopy): Use it.
* alloc.c (marked_pinned_symbols):
Use make_lisp_symbol instead of make_lisp_ptr.
(garbage_collect_1): Mark lispsym symbols.
(CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro.
(mark_object): Use it.
(sweep_symbols): Sweep lispsym symbols.
(symbol_uses_obj): New function.
(which_symbols): Use it. Work for lispsym symbols, too.
(init_alloc_once): Initialize Vpurify_flag here; no need to wait,
since Qt's address is already known now.
(syms_of_alloc): Add lispsym count to symbols_consed.
* buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0),
when testing whether storage is all bits zero.
* dispextern (struct image_type):
* font.c (font_property_table):
* frame.c (struct frame_parm_table, frame_parms):
* keyboard.c (scroll_bar_parts, struct event_head):
* xdisp.c (struct props):
Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
(syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
* frame.c (syms_of_frame): Add defsyms for the frame_parms table.
* keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.
(LISP_INITIALLY, TAG_PTR)
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT):
New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):
Move decls up, to avoid forward uses. Include globals.h earlier, too.
(make_lisp_symbol): New function.
(XSETSYMBOL): Use it.
(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.
Without this patch, "temacs -nw" fails with the diagnostic
"emacs: Symbol's function definition is void: frame-windows-min-size"
and messes up the tty's state.
* lib-src/make-docfile.c (write_globals):
Declare Fframe_windows_min_size with ATTRIBUTE_CONST, too. Sort.
* src/frame.c (Fframe_windows_min_size): New placeholder function.
(syms_of_frame): Define it.
* src/window.c (Fwindow__sanitize_window_sizes): New placeholder.
(syms_of_window): Define it.
* lisp/Makefile.in (THEFILE): Define to be 'no-such-file' by default,
to make it clearer that the caller must specify it.
(compile-onefile): Remove, replacing by ...
($(THEFILE)c): ... new rule. This lets us use AM_V_GEN here.
($(THEFILE)c, .el.elc, $(MH_E_DIR)/mh-loaddefs.el)
($(TRAMP_DIR)/tramp-loaddefs.el, $(CAL_DIR)/cal-loaddefs.el)
($(CAL_DIR)/diary-loaddefs.el, $(CAL_DIR)/hol-loaddefs.el):
Use AM_V_GEN to lessen 'make' chatter.
(.el.elc): Omit duplicate comment.
* src/Makefile.in (%.elc): Adjust to compile-onefile change in
../lisp/Makefile.in.
This cuts down on 'make' chatter a bit.
* doc/lispref/files.texi (Writing to Files):
* etc/NEWS: Document this.
* src/fileio.c (Fwrite_region):
Don't output "Wrote /whatever/foo.elc" if noninteractive.
* frame.c (x_set_frame_parameters): Call Fset_frame_size only if
f->can_x_set_window_size is true.
* xterm.c (x_set_window_size_1): Call change_frame_size with
text sizes instead of pixel sizes (Bug#19428).
These are dates that admin/update-copyright did not update, or
updated incorrectly. Also, back out the copyright-date change to
doc/misc/texinfo.tex, as upstream hasn't updated that date yet.
a5f90a3 * .gitattributes: New file.
5a9710f Make sure tool-bar changes are reflected on display.
93796ba * autogen.sh: Port better to non-GNU 'cp'.
9758516 Fix a typo in a comment in the previous commit.
aa472a3 Fix the pixel coordinates returned by pos-visible-in-window-p. (Bug#19473)
d261229 * automated/tramp-tests.el (tramp--test-smb-or-windows-nt-p): New defun. (tramp-test30-special-characters): Use it. (tramp--test-check-files): Filter nil file names out.
9278f05 Omit trailing white space

* Makefile.in (PAXCTL_if_present, SETFATTR_if_present): New macros.
(emacs$(EXEEXT), temacs$(EXEEXT), bootstrap-emacs$(EXEEXT)): Use them.
Simplify by using GNU make rather than shell conditionals,
by using ln -f rather than rm -f followed by ln,
and by preferring $@ to spelling out the destination.
* display.texi (Temporary Displays): Amend description of
`with-temp-buffer-window'. Add descriptions for
`with-current-buffer-window', `with-displayed-buffer-window' and
`temp-buffer-resize-mode', `temp-buffer-max-height' and
`temp-buffer-max-width'.
* frame.c (frame_inhibit_implied_resize): Escape left paren in
doc-string.
Also, the system-name variable is now obsolete.

* lisp/startup.el (system-name): Now an obsolete variable.
* src/editfns.c (cached_system_name): New static var.
(init_and_cache_system_name): New function.
(init_editfns, Fsystem_name): Use it.
(syms_of_editfns): Initialize it and Vsystem_name to the same value.
* src/sysdep.c [HAVE_SOCKETS]: Don't include <sys/socket.h>, <netdb.h>.
(h_errno) [TRY_AGAIN && !HAVE_H_ERRNO]: Remove decl.
(init_system_name) [HAVE_SOCKETS]: Don't canonicalize the name.
Don't create a new string if the current value is already correct.
* decompress.c, gnutls.c, image.c, xml.c:
If WINDOWSNT, use '#define FOO fn_FOO' to wrap dll functions,
rather than the inverse when not WINDOWSNT. This isolates the
fn_* business into the WINDOWSNT-specific section of the code,
which makes it easier to maintain the generic code.
* decompress.c (DEF_ZLIB_FN, LOAD_ZLIB_FN):
* gnutls.c (DEF_GNUTLS_FN, LOAD_GNUTLS_FN):
* image.c (DEF_IMGLIB_FN, LOAD_IMGLIB_FN):

Remove. All uses replaced by DEF_DLL_FN.
* w32.h (DEF_DLL_FN, LOAD_DLL_FN): New macros.
Instead of using gnutls_global_set_mem_functions, check every call
to a GnuTLS function that might return an indication of memory
exhaustion. Suggested by Dmitry Antipov in:
http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg02056.html
* src/gnutls.c (gnutls_global_set_mem_functions) [WINDOWSNT]: Remove.
(init_gnutls_functions): Do not load gnutls_global_set_mem_functions.
(fn_gnutls_global_set_mem_functions) [!WINDOWSNT]: Remove.
All uses removed.
(check_memory_full): New function.
(emacs_gnutls_handshake, emacs_gnutls_handle_error)
(gnutls_make_error, Fgnutls_boot): Use it.
(emacs_gnutls_global_init): Avoid gnutls_global_set_mem_functions.
* xsettings.c (parse_settings): Return the number of settings seen.
Count the settings changes accurately.
(read_settings): Don't confuse number of settings changes with
the return code from XGetWindowProperty.
216c6aa * net/tramp-sh.el (tramp-do-copy-or-rename-file-out-of-band): Use `tramp-rsh-end-of-line', it ought to be more robust.
