* src/xfns.c (setup_xi_event_mask): Select for
XI_TouchOwnership.
* src/xterm.c (xi_link_touch_point): Round X and Y and clear
ownership.
(xi_unlink_touch_point): Return 1 if the touch point is not
owned by Emacs, 2 otherwise.
(handle_one_xevent): Handle XI_TouchOwnership events and report
ownership correctly.
* src/xterm.h (enum xi_touch_ownership): New enum. Write
commentary on XI touch sequence ownership.
(struct xi_touch_point_t): Use integer X and Y. New field
`ownership'. Adjust for alignment.
Delete vc-deduce-fileset-1, taking advantage of set-buffer
* lisp/vc/vc.el (vc-deduce-fileset): Set buffer to the base
buffer, if any (bug#63949). That's to replace the more complex
previous strategy. vc-deduce-fileset is allowed to change the
current buffer, so why not do it for that case.
(vc-deduce-fileset-1): Delete, moving the meat of the logic back
to vc-deduce-fileset.
Like in `tab-bar-format-align-right', use `add-face-text-property' to
add 'mode-line' face on the `rest-str' string for `string-pixel-width'
to calculate the correct pixel width (bug#62606).
The Emacs regexp engine interprets character ranges from ASCII to raw
bytes, such as [a-\xfe], as not including non-ASCII Unicode at all;
ranges from non-ACII Unicode to raw bytes, such as [ü-\x91], are
ignored entirely.
To make rx produce a translation that works as intended, split ranges
that that go from ordinary characters to raw bytes. Such ranges may
appear from set manipulation and regexp optimisation.
* lisp/emacs-lisp/rx.el (rx--generate-alt): Split intervals that
straddle the char-raw boundary when rendering a string regexp from an
interval set.
* test/lisp/emacs-lisp/rx-tests.el (rx-char-any-raw-byte):
Add test cases.

Don't deliver touch or pinch events from master or slave devices
* src/xfns.c (setup_xi_event_mask): Select for gesture events on
only master devices if safe.
* src/xterm.c (handle_one_xevent): Deliver touchscreen events
only from direct slave devices, and gesture events only from
master pointers.
