The following commits were skipped:
fda43a7 Skip a vc-bzr test if run as root
4370b8e ; Copyright year fix No need to merge to master
305aca0 Backport: Handle unread-command-events consistently (bug#23980)
(map--plist-p, map--plist-delete): New functions.
(map-elt, map-delete, map-length, map-into, map-put!, map-insert)
(map-apply, map-do): Handle the plist case.
* test/lisp/emacs-lisp/map-tests.el (with-maps-do): Add sample plist.
(test-map-put!): The behavior of map-put! is not the same for plists as
for alists.
This fixes bug #33784.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context): While moving back
over enclosing parentheses, check that c-backward-token-2 actually moves.
* lisp/net/tramp-sh.el (tramp-set-remote-path): Use a temporary
file for setting $PATH, if it exceeds PATH_MAX on the remote system.
(tramp-send-command-and-read): Ignore errors if NOERROR. (Bug#33781)
* test/lisp/net/tramp-tests.el (tramp-test34-remote-path): New test.
* test/lisp/progmodes/flymake-tests.el
(flymake-tests--wait-for-backends): Skip rather than fail if
backends are slow to respond. This always seems like a temporary
system glitch and not something that should be reported as a failure.
* lisp/gnus/gnus-sum.el (gnus-summary-mode-group): New defvar for
passing gnus-newsgroup-name (a local variable) into the body of
gnus-summary-mode, so that it's available to gnus-summary-mode-hook.
Problem reported by Xu Chunyang (Bug#33731).
* lisp/emacs-lisp/cl-extra.el (cl-make-random-state):
Use copy-sequence, not copy-tree, so that the record is copied.
* test/lisp/emacs-lisp/cl-extra-tests.el:
(cl-extra-test-cl-make-random-state): New test.
* doc/lispintro/emacs-lisp-intro.texi (Files List): Simplify.
* doc/lispref/os.texi (Time of Day): Mention format-time-string
as an alternative to current-time-string.
* lisp/arc-mode.el (archive-unixdate, archive-unixtime):
Port better to future versions of Emacs where (COUNT . HZ)
will take precedence to (HI . LO).
* lisp/arc-mode.el (archive-unixtime):
* lisp/calendar/todo-mode.el (todo-insert-item--basic)
(todo-item-done, todo-read-time):
Prefer format-time-string to substringing current-time-string.
* lisp/calc/calc-forms.el (calc-time, calcFunc-now):
Prefer decode-time to parsing the output of current-time-string.
* lisp/emacs-lisp/cl-extra.el (cl--random-time):
Prefer encode-time to hashing the output of current-time-string.
* lisp/gnus/gnus-score.el (gnus-score-headers)
(gnus-score-adaptive):
Avoid stringifying and then reparsing timestamp.
* src/timefns.c (Fencode_time): Omit redundant assignment.
* test/lisp/vc/vc-bzr-tests.el (vc-bzr-test-faulty-bzr-autoloads):
Skip this test when run as root. This works around a race
condition in root-specific code in vc-mode-line when deleting a file.
; Do not merge to master, instead fix vc-mode-line there.
* src/keyboard.c (read_char): Events put into `unread-command-events'
with the form (t . EVENT) should always have the t stripped when read
out.
* test/src/keyboard-tests.el: New tests for `unread-command-events'.
(cherry picked from commit 1f3f4b1296)
The tests happen to not fail at the moment because find-library-name
now has an extra feature, find-library--from-load-history, which
happens to do a case-insensitive regexp match; but still it seems
better not to rely on this.
* test/lisp/progmodes/elisp-mode-tests.el (xref--case-insensitive):
New variable.
(xref-elisp-test-run, emacs-test-dir): Only downcase if the
filesystem seems to be case-insensitive.
* lisp/vc/diff-mode.el (diff-font-lock-keywords): Use diff-header face
for git index lines (like already used for bzr index lines).
Use diff-file-header face for binary file headers.
(diff-find-source-location): Use expand-file-name for vc-find-revision.
(diff--font-lock-prettify): Use diff-indicator-* faces for
left-fringe indicators.
(diff-syntax-fontify-props): Optimize to not use text-property-not-all
for font-lock-ensure.
* lisp/replace.el (occur-engine-line): Simplify to use font-lock-ensure
without text-property-not-all.
* lisp/vc/diff-mode.el (diff-hunk-text, diff-syntax-fontify-hunk):
Skip lines beginning with backslash like "\ No newline at end of file".
(diff-syntax-fontify-hunk): Use string-trim-right.
For one-line diffs use 1 explicitly in the list of line numbers.

* test/lisp/ibuffer-tests.el (ibuffer-filter-inclusion-3):
* test/lisp/net/tramp-tests.el (tramp-test42-remote-load-path):
Regexp-quote file names to avoid failures with directory names
of the form "build/emacs-i87jK3/emacs-26.1+1/...".
* src/data.c (emacs_mpz_mul_2exp): 2nd arg is now a
nonnegative EMACS_INT not mp_bitcnt_t, to simplify checking.
(Fash): Support COUNT values that are bignums or that
exceed mp_bitcnt_t range.
* test/src/data-tests.el (data-tests-ash-lsh): Test this.
Functions to access the first or all but the first elements of
sequences have been repeatedly asked for (the last occurrence being
https://github.com/NicolasPetton/seq.el/issues/9).
* lisp/emacs-lisp/seq.el (seq-first, seq-rest): New functions.
* test/lisp/emacs-lisp/seq-tests.el (test-seq-first, test-seq-rest):
New tests for seq-first and seq-rest.
(map-not-inplace, map-inplace): New errors.
(map-insert): New generic function.
(map-put!): Signal map-not-inplace rather than a generic 'error'.
(map-elt): Use map-not-inplace and map-insert to avoid hardcoding
a special case for lists.
* test/lisp/emacs-lisp/map-tests.el (test-map-put!): Rename from
test-map-put. Also test the errors signaled.
