Add some indexes and a cross-reference.

* doc/lispref/os.texi (Session Management, Desktop Notifications): Add
some indexes and a cross-reference.

* data.c (bool_vector_binop_driver): Rename locals for sanity's sake.

The old names predated the API change that put destination at end.

Improve API of recently-added bool vector functions.

The old API had (bool-vector-count-matches A B)
and (bool-vector-count-matches-at A B I), which gave the
misleading impression that the two functions were variants, one
with a location I.  The new API has (bool-vector-count-population A)
and (bool-vector-count-consecutive A B I) to make the distinction
clearer.  The first function no longer has a B argument, since the
caller can easily determine the number of nils if the length and
number of ts is known.
* src/data.c (Fbool_vector_count_population): Rename from
bool_vector_count_matches, and accept just 1 argument.
(Fbool_vector_count_consecutive): Rename from
Fbool_vector_count_matches_at.

It apparently doesn't work for GCC 3, and I suppose it's more
trouble than it's worth to worry about this.

* ps-print.el (ps-face-attribute-list): Handle anonymous faces

Fixes: debbugs:15827

Fix doc-string of display-buffer-other-frame.  (Bug#15868)

* window.el (display-buffer-other-frame): Fix doc-string.
(Bug#15868)

* xterm.c (syms_of_xterm): staticpro Qalt, Qhyper, Qmeta, and Qsuper.

This is safer, and it's what w32fns.c does.

* xterm.c (syms_of_xterm): staticpro Qmodifier_value.

* configure.ac: test portability fix
  (I can never remember whether this is still relevant or not)

Remove nt/msysconfig.sh

* configure.ac [MINGW32]: Source nt/mingw-cfg.site.

* make-dist: Don't distribute nt/msysconfig.sh.

* nt/msysconfig.sh: Remove.

* nt/INSTALL: Update for this.

* nt/mingw-cfg.site: Comment.

* Makefile.in (epaths-force-w32): Simplify w32srcdir computation.

* buffer.c (Fforce_mode_line_update): Don't fall off end of function

that requires a return value.
(Fset_buffer_modified_p): Take advantage of this change to do
a tail call.

Doc fixes.

* doc/lispref/os.texi (User Identification, Time of Day, Time Conversion): Minor fixes.

* lisp/subr.el (force-mode-line-update): Delete, move to buffer.c.
* src/buffer.c (Frestore_buffer_modified_p): Sync it with
Fset_buffer_modified_p.
(Fforce_mode_line_update): New function, moved from subr.el.
(Fset_buffer_modified_p): Use them.
(syms_of_buffer): Defsubr Fforce_mode_line_update.

* search.c (find_newline): Rewrite to prefer offsets to pointers.

This avoids undefined behavior when subtracting pointers into
different aways.  On my platform it also makes the code a tad
smaller and presumably faster.

* automated/tramp-tests.el (tramp-test-temporary-file-directory):
Check $TRAMP_TEST_TEMPORARY_FILE_DIRECTORY.
(tramp-read-passwd): Check $TRAMP_TEST_ALLOW_PASSWORD.

(tramp-sh-handle-file-local-copy): Don't write a message when
saving temporary files.

* net/tramp-smb.el (tramp-smb-handle-copy-directory): Fix bug when
both directories are remote.
(tramp-smb-handle-directory-files): Do not return double entries.
Do not expand full file names.

(tramp-smb-get-stat-capability): Fix a stupid bug.

* src/keyboard.c (command_loop_1): Use region-extract-function.
* src/insdel.c (Qregion_extract_function): Not static any more (can we
stop pretending that these vars can benefit from being marked static?).

* lisp/emacs-lisp/cconv.el (cconv-convert): Print warning instead of
throwing error over malformed let/let*.

Fixes: debbugs:15814
