bhsd 925775778a CodeMirror 6 for VE 2017 wikitext editor
Add new temporary ext.CodeMirror.visualEditor.init RL module which
selects the temporary ext.CodeMirror.visualEditor.v6 or non-v6 based on
$wgCodeMirrorV6. This will allow us to deploy CM6 further.

As a result of this work, the core CodeMirror class now has knowledge
of ve.ui.Surface.

Other changes:
* Add Compartment for specialCharsExtension so it can be disabled in VE.
* Add option to mediaWikiLang() to disable template folding.
* Add support for RTL wikis where $wgCodeMirrorRTL is enabled.
* Make CodeMirror.logUsage() and setCodeMirrorPreference() static.
* Fix unit and linting tests.
