If no revision is given to Special:Diff or PermaLink show a form
(cf. Special:ComparePages)
List these on Special:SpecialPages under "redirects".

Method similar to SpecialPage::outputHeader() to avoid registering
tons of system messages and to have -summary and -helppage tidily
listed together in Special:AllMessages by default.

$subpage being null is clearly documented in SpecialPage::run,
SpecialPage::execute, and most special page subclasses.
But all the redirect subclasses only copied part of the typehint,
making it look like it's always a string.
For SpecialMyLanguage, follows-up b1853bba0. Don't cast null to
empty string, and don't bother giving Title::newFromText an empty
string only to bail out with null again.
Also:
* Add visibility 'public' where missing.
* Add or correct relevant documentation comments.
* In SpecialMyRedirectPages, handle error first and avoid having
final return inside a conditional; Remove redunant 'else'.

Umherirrender found that I77fdaf8e has a flaw. Currently it is possible
to go to index.php?title=Special:Diff (without any trailing string),
and the page will be redirected to index.php?diff= which is the last diff
of the main page. However, the intended way to deal with this case is to
raise ErrorPageError. This patch fixes the problem.

This is similar to Special:PermanentLink added in r79036 and has been
asked for several times in different places, including:
- on the English Wikipedia (oldid=539308532)
- on mediawiki.org (lqt_oldid=31691)
- on the French Wikipedia (oldid=93029892)
- on the English Wikipedia again (oldid=588408888)
A notable use-case is linking to diffs in the edit summaries, where
external links are not yet allowed (bug 14892).
All of the following are valid usages:
- [[Special:Diff/12345]] (diff of a revision with the previous one)
- [[Special:Diff/12345/prev]] (diff of a revision with the previous one as well)
- [[Special:Diff/12345/next]] (diff of a revision with the next one)
- [[Special:Diff/12345/cur]] (diff of a revision with the latest one of that page)
- [[Special:Diff/12345/98765]] (diff between arbitrary two revisions)
