* lisp/x-dnd.el (x-dnd-use-offix-drop): New value `files', which
means to only drop files using the OffiX protocol. Make it the
default.

(x_free_frame_resources): Clear drag atom if owner was freed.
* src/xterm.h (struct x_display_info): New field
`motif_drag_atom_owner'.
* src/xterm.c (xm_get_drag_window): Avoid leak if error occured
creating drag window. Also use StructureNotifyMask instead of
ButtonPressMask.
(xm_get_drag_atom_1): Update. Make EMACS_DRAG_ATOM a list of
atoms and use the first one that isn't currently owned.
(xm_get_drag_atom): Stop owning selection here.
(xm_setup_drag_info): Record chosen atom.
(x_dnd_cleanup_drag_and_drop, x_dnd_begin_drag_and_drop)
(x_dnd_update_state, handle_one_xevent, x_connection_closed):
Use chosen atom.

* src/timefns.c (tzlookup, Fdecode_time): Use them.
(Ftime_convert): Convert to symbol once, instead of many times.
* test/src/timefns-tests.el (decode-then-encode-time)
(time-equal-p-NaN-NaN, time-arith-tests):
Don’t test time functions with infinities and NaNs,
which are not Lisp time values.
* src/timefns.c (tzlookup, lisp_time_hz_ticks)
(decode_time_components, lisp_to_timespec, lispint_arith)
(time_arith, time_cmp, Fdecode_time, Fencode_time)
(Ftime_convert): Prefer BASE_EQ to EQ where either will do.
Do not assume that the TZ environment variable is either unset or
agrees with /etc/localtime. I ran into this test bug while
running ‘TZ=America/Chicago make check’ on a platform where
/etc/localtime was America/Los_Angeles.
* test/lisp/calendar/icalendar-tests.el:
(icalendar-tests--decode-isodatetime): Don’t use
set-time-zone-rule, whose doc string says “Instead of calling this
function, you typically want something else” for a reason.
Instead, pass the zone arg to icalendar-test--format.
* src/xselect.c (x_handle_selection_request)
(Fx_get_selection_internal, syms_of_xselect): New variable
`x-selection-alias-alist'. Respect that alist of aliases.

(xm_get_drag_atom_1, xm_get_drag_atom): New functions.
(xm_setup_drag_info, x_dnd_cleanup_drag_and_drop)
(x_dnd_begin_drag_and_drop, x_dnd_update_state, handle_one_xevent)
(x_connection_closed, x_intern_cached_atom): Alias the drag atom
to XdndSelection. Use it instead of XdndSelection to set the
Motif index atom.
(x_get_atom_name): Handle new atoms.
(syms_of_xterm): New defsym.
* src/xterm.h (struct x_display_info): New fields for new atoms
and their names.
* lisp/ibuf-ext.el (ibuffer-format-qualifier-1): Do not display
nil in header for 0-ary filter qualifier.

was used.
(x-treat-local-requests-remotely): New defvar.
(x-dnd-convert-to-offix, x-dnd-do-offix-drop): New functions.

* lisp/whitespace.el (whitespace-style):
(whitespace-style-value-list):
(whitespace-toggle-option-alist):
(global-whitespace-toggle-options):
(whitespace-help-text):
(whitespace-interactive-char):
(whitespace-style-face-p):
(whitespace-color-on):
(whitespace-lines-regexp): New whitespace style `lines-char', which
highlights only the first character over the whitespace-line-column
limit (bug#55980).
* lisp/x-dnd.el (x-dnd-types-alist, x-dnd-known-types): Add
DndTypeFile and DndTypeText.

* src/xterm.c (x_atom_refs): Add DndProtocol and _DND_PROTOCOL.
(x_coords_from_dnd_message): Handle the old KDE protocol.
* src/xterm.h (struct x_display_info): New atoms.
* src/xterm.c (struct xm_drag_motion_reply): New struct.
(xm_read_drag_motion_reply): New function.
(x_coords_from_dnd_message): Handle those messages as well.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker)
(byte-optimize-let-form, byte-optimize-letX):
* lisp/emacs-lisp/bytecomp.el (byte-compile-unwind-protect):
Simplify source optimisation and codegen code that can now rely on
normalised let/let* and unwind-protect forms.
Make cconv work for dynamically bound code and always run it.
This allows later stages to benefit from transformations and
normalisations in cconv.
* lisp/emacs-lisp/bytecomp.el (byte-compile-preprocess): Always run
cconv.
* lisp/emacs-lisp/cconv.el (cconv--analyze-function)
(cconv-analyze-form): In dynbound code, treat all variable bindings
as dynamic (lambda, let, let* and condition-case).
Early normalisation of setq during macroexpand-all allows later
stages, cconv, byte-opt and codegen, to be simplified and duplicated
checks to be eliminated.
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all):
Normalise all setq forms to a sequence of (setq VAR EXPR).
Emit warnings if necessary.
* lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyze-form):

* lisp/emacs-lisp/bytecomp.el (byte-compile-setq):
Simplify.
* test/lisp/emacs-lisp/bytecomp-tests.el: Adapt and add tests.
* test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-nonvariable.el;
* test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-odd.el:
New files.
* lisp/international/iso-transl.el (iso-transl-char-map): Add
sequences for {AE,ae,G,g} with macron.
* lisp/leim/quail/latin-post.el ("latin-postfix"): Add missing entries
for {AE,ae,G,g} with macron.
* lisp/leim/quail/latin-pre.el ("latin-prefix"): Add entries for
'letter with macron' for {A,a,E,e,AE,ae,I,I,O,o,U,u,Y,y} with macron.
(Bug#55668)
* lisp/files.el (dir-locals-read-from-dir): We want the time stamp
of the actual file, not the time stamp of the symlink (if
.dir-locals.el is a symlink) (bug#46122).
* lisp/term/ns-win.el (global-map): set-frame-font asks for a font
using the minibuffer, but the former ns-popup-font-panel always showed
the graphical font panel on macOS. To preserve the same behavior,
bind it to menu-set-font, which is also called by Options, Set Default
Font (bug#55967).
* lisp/net/tramp.el (tramp-run-real-handler):
Handle also functions which use a `tramp-file-name' for the file
name handler. (Bug#55832)
(tramp-get-home-directory, tramp-get-remote-uid)
(tramp-get-remote-gid): VEC can also be nil.
