* ForkController, OrderedStreamingForkController: indeed pcntl_fork()
can't return false.
* RL\Image: Specify type instead of using suppression, since the issue
name changes.
* VueComponentParser: Accept complaint about nullable nodeValue.
* Disable PHP 8.0 polyfill stubs when running on PHP 8.0+ to avoid
duplicate interface errors.
* Add Socket stub and use it in LegacyHandler instead of multiple
existing suppressions.
* MemcachedPeclBagOStuff: accept complaint recommending !$result over
$result === false when the type is boolean.
* MemcachedPeclBagOStuff: fix probable bug, ignoring errors from
Memcached::getMulti(). Phan noticed that $res=false was unreachable,
but it should probably be reachable.
* DatabaseMysqli: accept complaint that $this->conn->errno is already
known to be an int. It was probably a hack for some previous version
of Phan.
* BcryptPassword, MWOldPassword, MWSaltedPassword: accept complaint that
the !is_string() checks are unnecessary, after code review of PHP.
* Pbkdf2PasswordUsingHashExtension: note that contrary to Phan's
suggestion, this check is necessary.
* DefaultPreferencesFactory: remove an existing hack for
array_diff_key(), no longer necessary on 7.4 and causes an error on
8.1. Use coalesce instead of cast for the remaining
array_intersect_key() hack since it better shows that we are casting
away null.
* FullSearchResultWidget: fix likely bug involving strict comparison
between a float and an int.
* SpecialWatchlist: accept complaint that $selectedHours is
unconditionally a float, being the return value of round(), and thus
the cast is unnecessary.
* Add stub for AllowDynamicProperties, resolving an error in User.php.
* Xml: accept complaint that $encMonth is already known to be an int.
Six errors remain. These need suppressions or otherwise conflict with
PHP 7.4 support.
