This is less likely to overflow, and avoids undefined behavior if
overflow does occur. All callers changed. Use strtoul to scan
for the unsigned long integer.

* 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.
* cm.c (tputs, tgoto, BC, UP): Remove extern decls. Include
tparam.h instead, since it declares them.
* cm.h (PC): Remove extern decl; tparam.h now does this.
* deps.mk (cm.o, terminfo.o): Depend on tparam.h.
* terminfo.c: Include tparam.h, to check interfaces.
(tparm): Make 1st arg a const pointer in decl. Put it at top level.
(tparam): Adjust signature to match interface in tparam.h;
this removes some undefined behavior. Check that outstring and len
are zero, which they always are with Emacs.
* tparam.h (PC, BC, UP): New extern decls.
* 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.
* character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
(FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
(FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
(BUF_DEC_POS): Be more systematic about renaming local temporaries
to avoid shadowing.
