I forgot this when I added this test case in I03a1e1a.
Also:
* Use another method to detect if the Cite extension is active. This
is the same method used in the actual code.
* Move a line of code into the `if` it belongs to.

This patch also minifies existing code. Note that [] is true in
JavaScript, unlike in PHP.

Introduces a new config variable `CodeMirrorLineNumberingNamespaces`
that can restrict line numbering to only appear for specified
namespaces. Setting to null enables everywhere.
This takes some liberties with the `lib` module, turning it into a
container for shared functionality. This can be pursued in later
work, by cleaning up duplicated code in this repo.
FIXME: failed to deduplicate the code for now.

These changes to the color scheme are hidden behind a feature

This does not have an effect any more with all the other
optimizations in place.

While working on T270317, I realized the performance of the
matchbrackets addon is not as good as described in
T270237#6739993. The issue with my original benchmark was that
I did it with a single pair of brackets with thousands of
characters between. A paragraph with thousands of brackets
behaves much worse. So bad that I feels painful when moving
the cursor.
Lowering the limit to something in the middle (between the
original 1000 and my 10000) makes it behave much, much better
on my machine.

some typos.

The addon does have 3 settings:
- maxHighlightLineLength is for the current line where the
cursor is. Bracket matching is simply not done when the
current line is longer. The default is 1000, which is rather
low.
- maxScanLineLength is for every other line that is scanned in
the process. I don't understand why, but this limit is 10x
higher.
- maxScanLines is the number of lines that can be scanned.
Simply raising the first to be 10000 as well fixes our issue.
Note that CodeMirror does have a limit of 10000 anyway. It's
called maxHighlightLength there. Lines that are longer get
syntax highlighting only for the first 10000 characters. The
rest of the line is black. Using the same limit in the addon
makes it's behavior consistent. Means: The user can see when
the syntax highlighting stops, and bracket matching stops
working the same time.
I benchmarked with both settings. It doesn't have a measurable
effect. Bracket matching is done in <1ms in both cases.

The addon does support some configuration options. These are passed
as properties of the `matchBrackets` CodeMirror option. Just passing
the boolean there hides that fact.

Optimizations for the code introduced in Ic403e0a:
* Skip this entirely when something is selected (as discussed
in Ic403e0a).
* Use a combination of existing methods. I benchmarked these
again. This approach is "significantly" slower compared to
the custom code from before. However, "significantly" here
means something like 1 nanosecond vs. 4 nanoseconds. Both
is effectively nothing.
* Use the same approach in another place. This one is triggered
every time a change is made, e.g. a character typed. I
benchmarked this as well. The new code is about 500x faster
(yes, seriously).

Deferring the insertions can lead to sync issues, so use
a different technique to selective refresh the CodeMirror
view when the height changes.

Due to using bold as a highlight style, the VE overlay technique
will only work with monospaced fonts.

CM surface is just for presentation, it shouldn't
be possible to focus or select anything in the surface,
so in addition to it being beneath the VE surface,
disable it through the CM API and disable pointer-events
with CSS.

Long-term todo:
* Performance will be poor on large pages due
to using a auto-height textarea which CodeMirror
doesn't optimise.
