Make the context switch code handle buffer-local variables more
correctly by reusing the code originally written for `backtrace-eval`.
This has the side benefit of making the `saved_value` field unused.
* src/lisp.h (enum specbind_tag): Remove `saved_value` field.
(rebind_for_thread_switch, unbind_for_thread_switch): Delete decls.
(specpdl_unrewind): Declare function.
* src/eval.c (specpdl_saved_value): Delete function.
(specbind): Delete the code related to `saved_value`, and consolidate
common code between the different branches.
(rebind_for_thread_switch, -unbind_for_thread_switch): Move to `thread.c`.
(specpdl_unrewind): New function, extracted from `backtrace_eval_unrewind`.
Use `SET_INTERNAL_THREAD_SWITCH`. Skip the buffer & excursion unwinds
depending on new arg `vars_only`.
(backtrace_eval_unrewind): Use it.
(mark_specpdl): Don't mark `saved_value`.
* src/thread.c (rebind_for_thread_switch, unbind_for_thread_switch):
Move from `eval.c` and rewrite using `specpdl_unrewind`.
* test/src/thread-tests.el (threads-test-bug48990): New test.
* test/Makefile.in (test_template): Add a + as suggested by make:
"warning: jobserver unavailable: using -j1. Add '+' to parent make rule".
* lisp/emacs-lisp/comp-cstr.el (comp-cstr-set-range-for-arithm):
When one of the two sources is negated revert to set dst as
number.
* test/src/comp-tests.el (comp-tests-type-spec-tests): Add test to
verify this is effective.
* test/lisp/electric-tests.el (electric-pair-define-test-form):
* test/src/buffer-tests.el (buffer-tests--make-test-name): Silence
byte-compiler by defining defuns also at run time.
* test/src/filelock-tests.el (filelock-tests--fixture): Make it a
defmacro. Adapt callees.
(filelock-tests-unlock-spoiled, filelock-tests-kill-buffer-spoiled):
Simplify.
(filelock-tests-detect-external-change): New test
* doc/lispref/display.texi (Logging Messages): Document it.

* src/print.c (print_vectorlike): Use the variable.
(syms_of_print): New variable print-unreadable-function
(bug#52566).
Fchar_syntax did not convert unibyte characters to multibyte when the
current buffer was unibyte, in contrast to `char-syntax` in
byte-compiled code (bug#53260).
* src/bytecode.c (exec_byte_code): Call out to Fchar_syntax;
the dynamic frequency is too low to justify inlining here, and it
did lead to implementations diverging.
* src/syntax.c (Fchar_syntax): Convert non-ASCII unibyte values to
multibyte.
* test/src/syntax-tests.el (syntax-char-syntax): New test.
* test/src/inotify-tests.el (inotify-rm-watch):
* test/src/lcms-tests.el (lcms-xyz->jch):
* test/src/sqlite-tests.el (sqlite-open):
Add declarations to prevent byte-compilation warnings when features
are absent.
* test/src/filelock-tests.el (filelock-tests-file-locked-p-spoiled)
(filelock-tests-unlock-spoiled)
(filelock-tests-kill-buffer-spoiled): Expect 'permission-denied' only
on MS-Windows.
* src/fileio.c (syms_of_fileio) <permission-denied>: Define the
symbol and its 'err-conditions' and 'error-message' properties.
(get_file_errno_data): Return permission-denied on EACCES.
* test/src/filelock-tests.el (filelock-tests-file-locked-p-spoiled)
(filelock-tests-unlock-spoiled)
(filelock-tests-kill-buffer-spoiled): Adapt the tests to the new
error symbol.

(GCALIGNED_STRUCT): New struct to keep data for sqlite database
objects and statement objects.

the objects.

* src/print.c (print_vectorlike): Add a printer for the sqlite
object.
* src/sqlite.c: New file.
* test/src/sqlite-tests.el: Add tests.
Move `require`s out of `eval-when-compile` if the functions are called
at run-time.
Don't use #' to quote symbols (i.e. at those places where a lambda
expression couldn't be used).
Don't pre-load comp-test-45603.el and comp-test-pure.el any more.
(comp-deftest pure): Use `declare-function` after loading `comp-test-pure.el`
to silence the byte-compiler.
* test/lisp/calendar/icalendar-tests.el
(icalendar-tests--decode-isodatetime):
* test/src/eval-tests.el
(eval-tests-19790-backquote-comma-dot-substitution):
Change `defun` into `ert-deftest` where this seems to have been the
original intention.
* test/infra/gitlab-ci.yml (test-native-comp-speed0)
(test-all-inotify): Do not exclude emacs-module-tests.el.
* test/src/emacs-module-tests.el
(module--test-assertions--load-non-live-object)

(module--test-assertions--call-emacs-from-gc)
(module--test-assertions--globref-invalid-free): Tag them as
:unstable on emba. (Bug#50902)

* src/bidi.c (bidi_find_first_overridden): Extend to detect more
subtle effects of directional formatting controls, to include
embeddings and isolates.
* src/xdisp.c (Fbidi_find_overridden_directionality): Accept an
additional argument BASE-DIR to specify the base direction of the
paragraphs.
* lisp/international/mule-cmds.el (confusingly-reordered): New
face.
(reorder-starters, reorder-enders): New variables.
