(bug 16020) Fix race condition in User::addToDatabase()

Fix the DB error which comes from User::addToDatabase() if it is called
when the user already exists. This is the most common DB error we log at
WMF in normal operation, perhaps because of double clicks on the "create
account" button, or perhaps due to CentralAuth autocreation when
multiple pages on another wiki are opened in the browser simultaneously,
as the bug reporter suggests.

See the doc comment for the interface rationale. Patched
Special:Userlogin to be aware of the new return value. Most extension
callers will continue to work, I will patch a couple that need it in
subsequent commits.

Stop expanding search term in <title> of the search results page

When entering a search term such as {{SITENAME}} on Special:Search,
the <title> was generated with template expansion.

This patch prevents transformation by using search term as rawParams
of the 'searchresults-title' and 'pagetitle' messages.

Fix test SpecialSearchTest.testSearchTermIsNotExpanded

Ief0bdd10 / 9299bab "Stop expanding search term in <title> of the search
results page" had an issue comparing the site title that could be in
different language.  I have converted the assertion to make sur we
always have the plain search term (aka: {{SITENAME}}) which will work
regardless of the language currently set.

Add three tests for categories mixed with templates.

Apparently we didn't catch a regression in this area, so I've added
a set of tests to make sure we don't miss it again.

mediawiki.language.convertPlural depends on currentUI language from

restore it at teardown of QUnit.
