Abstract the implementation of intervals in icalendar-recur.el. Don't

Rearrange loops when refining subintervals, so that the loop always runs
once but doesn't run a second no-op iteration. Astonishingly this cuts
the running time of the full test suite by almost 50%.

Improve performance of `icalendar-recur-tz-observance-on'. This also
brings about a ~20% performance gain.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-tz-observance-on): Eliminate calculation of previous
interval recurrences when it's unnecessary. Add a cheap upper bound check to
prevent fully computing recurrences for irrelevant observances.
(icalendar-recur--w/in-locally-p):
(icalendar-recur--w/in-abs-p): New helper functions for the upper bound check.
Other more minor changes:
Improve performance in `icalendar-recur-refine-byday'
* lisp/calendar/icalendar-recur.el (icalendar-recur-refine-byday): Avoid
calculating Gregorian from absolute date unless it's necessary.
Improve performance of BYSETPOS filtering in icalendar-recur.el:
η-reduce `icalendar-recur-make-bysetpos-filter'.
Thanks to Mattias Engdegård for the suggestion and implementation.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-make-bysetpos-filter): Rename to
`icalendar-recur-bysetpos-filter' and avoid `seq-map-indexed'.
(icalendar-recur-recurrences-in-interval): Use new function.
* test/lisp/calendar/icalendar-recur-tests.el
(icalendar-test-recur-bysetpos-filter): Use new function.
Improve sorting performance:

(icalendar-recur-refine-byweekno):

calls.
Eliminate `apply-partially' and `seq-take':
Thanks to Mattias Engdegård for the suggestion and implementation.
* lisp/calendar/icalendar-recur.el
(icalendar-recur-recurrences-in-window): Eliminate `apply-partially'.
(icalendar-recur-recurrences-in-interval): Eliminate

Reduce consing:

(icalendar-recur-subintervals-to-dates):
(icalendar-recur-recurrences-in-window):
(icalendar-recur-recurrences-in-window-w/end-times):
(icalendar-recur-recurrences-to-count): Replace `append' with `nconc'.
Avoid a few uses of `seq-filter' in common functions in icalendar-ast.el:
* lisp/calendar/icalendar-ast.el (icalendar-ast-node-children-of):
Reimplement filter imperatively.
* test/lisp/dired-tests.el (dired-test-ls-error-message):
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Use
`string-match-p' instead of `equal' because the error message may
report e.g. "/bin/ls" even though the value of
`insert-directory-program' is "ls".
* test/lisp/dired-tests.el (dired-test-ls-error-message):
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Make test
comparing the expected 'ls' error message with the string in the
'ls' error buffer more robust (bug#80499).
* lisp/subr.el (listify-key-sequence): The funny
"7th bit is Meta" applies only to unibyte strings.
* test/lisp/subr-tests.el (subr-listify-key-sequence): New test.
Before the fix, if user uses the NODE-ONLY option, we don't keep
the capture names in the results, then predicates won't work
because they can't reference capture names.
* src/treesit.c (query_capture_remove_capture_name): New
function.
(Ftreesit_query_capture): Use the new function to remove capture
names AFTER running the predicate.
* test/src/treesit-tests.el:
(treesit-query-node-only-and-grouped): New test.
* test/lisp/progmodes/python-tests.el (python-ts-mode-dotted-decorator-face-2)

after setting a var that may flush the font-locking.
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Account for
'ls' error messages which designate 'ls' differently, e.g. as
'gls' or '/bin/ls' and which use different or no quoting of the
file name.
This change updates gnus-icalendar.el to use the new iCalendar
library instead of obsolete functions from icalendar.el.

(Bug#80499)
The error messages are now displayed in a popped up buffer instead
of being output in the Dired buffer and signalling an error. The
file name bounds in Dired entries are now determined solely by the
offsets calculated by 'ls' with the --dired option and
consequently Dired now reliably recognizes file names that contain
a newline (bug#80499).
* etc/NEWS: Announce new Dired handling of errors from 'ls'.
* lisp/dired.el (dired-internal-noselect): Check Dired buffer for
file entries and if there are none kill the buffer to prevent
displaying a Dired buffer with no file entries.
(dired--ls-error-buffer): New variable.
(dired--display-ls-error): New function.
(dired, dired-other-window, dired-other-frame, dired-other-tab):
Use it to pop up buffer with error message emitted by 'ls'.
* lisp/files.el (insert-directory-clean): Remove the code that
treats lines beginning at column 0 in a Dired buffer as error
lines and consequently also remove the code using these lines to
adjust the offsets specifying the bounds of the file name in the
Dired entries. If the buffer contains a //DIRED-OPTIONS// line
output by --dired, delete this line even when it is at BOB.
(insert-directory): Remove the code that checks the return value
of 'ls' and signals an error based on that value. Write any error
message emitted by 'ls' to a temporary file and insert its content
into a buffer, which will be popped when invoking a Dired command
results in the 'ls' error. Adjust the comment above this function
to accommodate file names containing a newline in Dired entries.
(insert-directory-adj-pos): Remove this now unused function.
* test/lisp/dired-tests.el (dired-test-filename-with-newline-1)
(dired-test-filename-with-newline-2)
(dired-test-ls-error-message): New tests.
* test/lisp/files-tests.el
(files-tests-file-name-non-special-insert-directory): Adjust test
to use of 'ls' error buffer instead of signaling an error.
This introduces the predicate frame-initial-p, which uses
struct frame.output_method or struct terminal.type to detect
initial_terminal without relying on its name (bug#80629).

Eliminate 'vtable--limit-string' in favor of the more efficient
'truncate-string-pixelwise'. Remove extraneous pre-measurement
calls to 'string-pixel-width' and ellipsis concatenation as
'truncate-string-pixelwise' does both.
The 'make-vtable' 'ellipsis' keyword can be a string to override
the default returned by 'truncate-string-ellipsis'.
