(tramp-get-connection-property): Improve debug messages.
Suggested by Marc Herbert <marc.herbert@gmail.com>.
* lisp/net/tramp-cache.el (tramp-dump-connection-properties):
Remove compatibility code dumping the persistency file. Use
`emacs-lisp-mode' for backward compatibility.
Fixes: bug#40573
The new mode can be used stand-alone or inherited from by modes
intended to edit programs. The existing emacs-lisp-mode and lisp-mode
are examples.
Thanks to Juri Linkov and Basil L. Contovounesios for researching some
data files in Emacs that can be automatically set to use the new mode.

".dir-locals-2"

will show the nick in the same case used during registration, but
it allows case-insensitive matches when logging in. Therefore, we
should accept response messages regardless of case.
This is a companion to the recent set-file-modes patch.
It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773).
Like the set-file-modes patch, it needs work in the w32 port.
* admin/merge-gnulib (GNULIB_MODULES): Add futimens, utimensat.
Remove utimens.

When setting file times, avoid following symbolic links
when the file is not supposed to be a symbolic link.
* lib/futimens.c, lib/utimensat.c, m4/futimens.m4, m4/utimensat.m4:
New files, copied from Gnulib.
* lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file):
When creating a file that is not supposed to exist already,
use the excl flag to check this.

* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-times):
* src/fileio.c (Fset_file_times):
Support an optional FLAG arg.
* src/fileio.c (Fcopy_file): Use futimens instead of set_file_times,
as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
* lisp/net/tramp-adb.el (tramp-adb-handle-file-local-copy): Do not use
'nofollow for temporary files. Use `tramp-compat-set-file-modes'.
(tramp-adb-handle-write-region): Do not use 'nofollow for
temporary files.
(tramp-adb-handle-set-file-modes): Implement FLAG.
* lisp/net/tramp-compat.el (tramp-compat-file-modes)
(tramp-compat-set-file-modes): New defaliases.
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-modes):
Make explicit check (eq flag 'nofollow).
* lisp/net/tramp-sh.el (tramp-sh-handle-set-file-modes): Implement FLAG.
(tramp-do-copy-or-rename-file-directly)
(tramp-sh-handle-file-local-copy, tramp-sh-handle-write-region):

* lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-set-file-modes):
Implement FLAG.
(tramp-sudoedit-handle-write-region): Use `tramp-compat-set-file-modes'.
* lisp/net/tramp.el (tramp-default-file-modes): Optional argument FLAG.
(tramp-handle-file-modes): Use `file-truename' instead of
`file-chase-links'. The latter function does not work for remote
file names.
(tramp-handle-write-region): Call `tramp-default-file-modes' with
'nofollow if needed. Do not use 'nofollow for temporary files.
* test/lisp/net/tramp-tests.el
(tramp--test-ignore-make-symbolic-link-error): Check also for
"Cannot chmod .* with nofollow flag" error.
(tramp-test20-file-modes): Extend test.
(tramp--test-emacs28-p): New defun.
This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.
