Security and maintenance release: 1.35.7 / 1.37.3 / 1.38.2

I would like to announce the release of MediaWiki 1.35.7, 1.37.3 and
1.38.2! There was no pre-release announcement as the security fixes being
included are low risk XSS vulnerabilites that aren't exploitable in the
default MediaWiki config. The patches have also been committed to git for a
while.

These releases also serve as a maintenance release for these branches.

While tarballs have already been uploaded as of this e-mail, git tags will
follow later on today.

An "MediaWiki Extensions Security Release Supplement" e-mail will follow
this one, covering security updates for non-bundled extensions.

T308473 only applies to MediaWiki > 1.35. Therefore the fix has not been
back-ported to 1.35.

T309377 only applies to MediaWiki 1.35 due to having guzzlehttp/guzzle
6.5.5. MediaWiki >= 1.36 already had been upgraded to guzzlehttp/guzzle to
7.2. The patch for MediaWiki 1.35 in T309377 was superseded by the
subsequent guzzlehttp/guzzle update in T311384.

Various patches aimed at PHP 8.0 and PHP 8.1 support have been backported.
This should fix a lot of log spam, and MediaWiki should work on both
versions.

Bug reports on PHP 8.0 and 8.1 are very welcome, and fixes will be
back-ported when possible. Please see
https://phabricator.wikimedia.org/tag/php_8.0_support/ and
https://phabricator.wikimedia.org/tag/php_8.1_support/ for the relevant
work boards.
