PHPUnit 3.7.0 was the first version to support @requires extension. At
the time checkPHPExtension() was added in a7901801b4, MediaWiki
still supported PHPUnit 3.6.7.
MediaWiki now requires intl and xml, so I removed checks for those
extensions rather than converting them to annotations.
checkPHPExtension() is removed without deprecation; it does not appear
to have ever been used (and is not likely to be used) in MW extensions.
This is explicitly permitted under the stable interface policy. Even if
it were not, only tests are affected, and they are supposed to fail
anyway if hard deprecated code is used.

Add a collation that gets its data from a remote Shellbox instance. This
is meant as a migration helper to use during an ICU upgrade.
Add a batch method to Collation so that this can be somewhat efficient
when adding multiple categories.
