* autogen/: New directory, to be excluded from releases.
* autogen/copy_autogen, autogen/update_autogen: New scripts.
* autogen/README: New file.
* autogen/aclocal.m4, autogen/config.in, autogen/configure:
* autogen/Makefile.in: Add auto-updated generated files.
* autogen.sh: No longer a no-op, now it tests for autotools
and runs them as necessary.
* configure.in: Defaule maintainer-mode to on.
* aclocal.m4, configure, lib/Makefile.in: Remove files.
* src/config.in: Remove file.
* INSTALL.BZR, admin/make-tarball.txt: Update instructions.
* minibuf.c (Vcompleting_read_function): Don't declare, global variables
are now in src/globals.h.
(syms_of_minibuf): Remove spurious & from previous change.
* buffer.h (BUF_BEGV, BUF_BEGV_BYTE, BUF_ZV, BUF_ZV_BYTE, BUF_PT)
(BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
These macros can no longer be used for assignment.
* buffer.c (Fget_buffer_create, Fmake_indirect_buffer): Assign
struct members directly, instead of using BUF_BEGV etc.
(record_buffer_markers, fetch_buffer_markers): New functions for
recording and fetching special buffer markers.
(set_buffer_internal_1, set_buffer_temp): Use them.
* lread.c (unreadchar): Use SET_BUF_PT_BOTH.
* insdel.c (adjust_point): Use SET_BUF_PT_BOTH.
* intervals.c (temp_set_point_both): Use SET_BUF_PT_BOTH.
(get_local_map): Use SET_BUF_BEGV_BOTH and SET_BUF_ZV_BOTH.
* xdisp.c (hscroll_window_tree):
(reconsider_clip_changes): Use PT instead of BUF_PT.
That way, the code declares only the vars that it needs.
* s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
* s/cygwin.h (PTY_ITERATION): Likewise.
* s/darwin.h (PTY_ITERATION): Likewise.
* s/gnu-linux.h (PTY_ITERATION): Likewise.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Make it work to
inline lexbind interpreted functions into lexbind code.
(bytedecomp-bytes): Not a dynamic var any more.
(disassemble-offset): Get the bytes via an argument instead.
(byte-decompile-bytecode-1): Use push.
* lisp/emacs-lisp/bytecomp.el: Remove the bytecomp- prefix now that we use
lexical-binding.
(byte-compile-outbuffer): Rename from bytecomp-outbuffer.
* lisp/emacs-lisp/cl-macs.el (load-time-value):
* lisp/emacs-lisp/cl.el (cl-compiling-file): Adjust to new name.
* lisp/emacs-lisp/pcase.el (pcase-mutually-exclusive-predicates):
Add byte-code-function-p.
(pcase--u1): Remove left-over code from early development.
Fix case of variable shadowing in guards and predicates.
(pcase--u1): Add a new `let' pattern.
* src/image.c (parse_image_spec): Use Ffunctionp.
* src/lisp.h: Declare Ffunctionp.
