* src/lisp.h (struct Lisp_Symbol): Change xname to meaningful
name since all xname users are fixed long time ago. Do not use
INTERNAL_FIELD.
(set_symbol_name, set_symbol_function, set_symbol_plist):
(set_symbol_next, set_overlay_plist): New function.
(struct Lisp_Cons): Do not use INTERNAL_FIELD.
(struct Lisp_Overlay): Likewise.
(CVAR, MVAR, SVAR): Remove.
* src/alloc.c, src/buffer.c, src/buffer.h, src/bytecode.c:
* src/cmds.c, src/data.c, src/doc.c, src/eval.c, src/fns.c:
* src/keyboard.c, src/lread.c, src/nsselect.m, src/xterm.c:
Adjust users.
* src/.gdbinit: Change to use name field of struct Lisp_Symbol
where appropriate.
* admin/coccinelle/overlay.cocci, admin/coccinelle/symbol.cocci:
Remove.
* src/lisp.h (struct Lisp_Cons): Use INTERNAL_FIELD.
Remove obsolete comment.
(MVAR): New macro.
(struct Lisp_Overlay): Use INTERNAL_FIELD.
* src/alloc.c, src/buffer.c, src/buffer.h, src/fns.c: Adjust users.
* admin/coccinelle/overlay.cocci: Semantic patch to replace direct
access to Lisp_Object members of struct Lisp_Overlay to MVAR.
* src/process.h (PVAR): New macro. Adjust style.
(struct Lisp_Process): Change Lisp_Object members to INTERNAL_FIELD.
* src/print.c, src/process.c, src/sysdep.c, src/w32.c:
* src/xdisp.c: Users changed.
* admin/coccinelle/process.cocci: Semantic patch to replace direct
access to Lisp_Object members of struct Lisp_Process to PVAR.
* src/lisp.h (build_unibyte_string): New function.
* src/dosfns.c, src/fileio.c, src/fns.c, src/ftfont.c, src/process.c:
* src/sysdep.c, src/w32fns.c, src/xfns.c: Use it.
* src/font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
of type Lisp_Object to avoid redundant calls to make_unibyte_string.
Adjust users accordingly.
* src/font.h (font_open_by_name): Adjust prototype.
* admin/coccinelle/unibyte_string.cocci: Semantic patch to convert from
make_unibyte_string to build_unibyte_string where appropriate.
* admin/coccinelle/list_loop.cocci: Semantic patch to convert from Fcdr
to XCDR and consistently use CONSP in the list iteration loops.
* admin/coccinelle/vector_contents.cocci: Fix indentation.
* src/callint.c, src/coding.c, src/doc.c, src/editfns.c, src/eval.c,
* src/font.c, src/fontset.c, src/frame.c, src/gnutls.c, src/minibuf.c,
* src/msdos.c, src/textprop.c, src/w32fns.c, src/w32menu.c, src/window.c,
* src/xmenu.c: Changed to use XCAR and XCDR where argument type is known
to be a Lisp_Cons.
* src/lisp.h: Define build_string as static inline. This provides
a better opportunity to optimize away calls to strlen when the
function is called with compile-time constant argument.
* src/image.c (imagemagick_error): Convert to build_string.
* src/w32proc.c (sys_spawnve): Likewise.
* src/xterm.c (x_term_init): Likewise.
* admin/coccinelle/build_string.cocci: Semantic patch
to convert from make_string to build_string.
* coccinelle: New subdirectory
* coccinelle/README: Documentation stub.
* coccinelle/vector_contents.cocci: Semantic patch to replace direct
access to `contents' member of Lisp_Vector objects with AREF and ASET
where appropriate.
