API warnings and error messages are currently hard-coded English
strings. This patch changes that.
With a few exceptions, this patch should be compatible with non-updated
extensions:
* The change to ApiBase::$messageMap will blow up anything trying to
mess with it.
* The changes to the 'ApiCheckCanExecute' hook will cause a wrong
(probably unparsed) error message to be emitted for extensions not
already using an ApiMessage. Unless they're currently broken like
Wikibase.

All tests based on APITestCase can be slow. I've also seen more than one
Jenkins failure due to GlobalTest::testMerge timing out.
Also, added a meta-test on APITestCase to make sure that all its
subclasses are marked with @group medium or @group large, to prevent new
tests from re-causing the bug.

Changeset Iec98e472 changed the behavior of action=parse&page=... when
passed a page that does not exist: previously, it would return a
"missingtitle" error instead of assuming an empty page. As some people
had been depending on this old behavior, restore the error checking.
