The 2017 editor has an infinite viewport, meaning the entire document is
printed on page load. CodeMirror 6 meanwhile only processes text in the
visible viewport. This presents a situation where if large chunks of
text are inserted outside the visible range (such as the "Changes
recovered" feature of VE), it can cause misalignment of the VE surface
and visible CodeMirror layer, as CodeMirror has not accounted for the
off-screen lines of text.
CodeMirror 5 had a `viewportMargin: infinity` option that prevented this
issue, but at the cost of performance. CodeMirror 6 removed this option,
but the same effect can be achieved by tricking CodeMirror into thinking
we're printing the document, in which case it will process all lines.
This seriously hurts performance, and is a nasty hack, but until the
2017 editor is reworked to have a viewport, there may be no other means
to prevent the misalignment.

triggerHandler will not bubble up the DOM, which is necessary for some

This patch applies the fix to both CodeMirror 5 and CodeMirror 6.

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.

This patch fixes a few minor issues in the tokenizer, including indented table (T108454), tag name followed by punctuations (T357720), free external link ending with `~` and `'` (T358643), and Hebrew parser function containing whitespace (T170004).

CodeMirror 6 requires the use of NPM, but we can still bundle all CM
packages into one file, and then everything else (i.e. our code) is
managed by ResourceLoader as per usual. This makes contribution
considerably easier as we no longer need a build step for each change.
CM5 files are now under resources/legacy, and the CM6 files are moved to
the root of the resources/ directory. Only one file,
codemirror.bundle.js, is managed by Rollup, while everything else is RL.
The Rollup output for now is put under resources/lib/ alongside the CM5
upstream files.
This patch is *mostly* renames of files, along with changing ECMAScript
Module (ESM) syntax into the CommonJS style that ResourceLoader prefers.
We also remove more modern JS syntax (i.e. private class methods) that
we were able to use before because we had a build step with Babel.
This patch should effectively make no user-facing changes, or to the
ResourceLoader modules we offer in Extension:CodeMirror.
Finally, bump version in extension.json to 6, to match the upstream lib,
and add Bhsd as an author :-)

This is a short-gap measure to make the 2017 editor + dark theme more
readable. Implementing a dark theme for all of the MediaWiki tokens will
come in a future patch.

New pages do not have body content yet, so the LTR check added with
If3825d6e54 failed. This commit adds the document root (<html> element)
as the fallback, so CodeMirror can be used on new pages.
This is just a quick fix. CM6 for VE 2017 wikitext editor is almost
done, and that will come with RTL support (T357482).

Brings it down from ~3 secs on my machine to ~600 ms.
This also allows for debuggers, and essentially eliminates the need
for source maps on your local (though we should probably still look
into them for prod).
