The API has wrapped its pretty-printed output since Id9cdf102. Apply an
appropriate class to preserve this now that GeSHi is handling it.
Unfortunately GeSHi itself doesn't support adding more than one arbitrary class
to the <pre> (and we're already using that), so we have to add it in a
post-processing step.

The version was set from the ExtensionTypes hook (which runs only on
Special:Version). WikiApiary and other API consumers were unable to
detect the version.
This is an amended resubmission of the reverted d69ae1f3ac, in which
the constant was declared twice.
Change include_once to require_once for langs file (follows-up 168e1296).

Store the list of supported languages in SyntaxHighlight_GeSHi.langs.php, which
is auto-generated via a maintenance script, updateLanguageList.php.

Core change I04b1a3842 adds a hook to allow extensions to
syntax-highlight the pretty-printed output from the API.

We could do this using TextContent::fillParserOutput(), but alas it is
'protected', so we have to duplicate a tiny bit of code from there.

We want to be able to track what styles were added to be able to deliver
this information to MediaWiki's live preview functionality (in order
to solve bug 24134).
This required moving some code in SyntaxHighlight_GeSHi class around.
The old way still works and is used for MediaWiki 1.20 and lower.

HTML Tidy doesn't care for tabs, and likes to always output spaces. This
can break the syntax-highlighted output, since Tidy converts tabs to
spaces on the source-code level instead of on the rendered HTML level,
even inside <pre> tags where it really shouldn't (this is probably a bug
in Tidy).
r97300 fixed the bad indenting by converting tabs to spaces before
highlighting, which works around Tidy's bug but breaks highlighting of
languages where tabs are significant (e.g. Whitespace).
It turns out that Tidy's tab mangling occurs while it's reading the
source file, before the conversion of entities such as 	 to tab. So
GeSHi can armor its <pre>-wrapped output against Tidy's bug by encoding
all tabs as 	.

Currently, the SyntaxHighlight GeSHi extension includes geshi/geshi.php.
This creates a conflict when an up to date GeSHI library exists in PHP included path.
This change let the SyntaxHighlight GeSHi include our bundled version instead.

Using ContentGetParserOutput instead of ShowRawCssJs allows highliting to be applied
for other kinds of scripts as well (e.g. Lua). It also allows more special case code
for CSS and JS to be phased out.
NOTE: this requires Ibfb2cbef to be merged in core!

(...modules of unusual size.)
Enabling full syntax highlighting for very long Lua modules can produce DOMs
that have hundreds of thousands of elements and cause browsers to lock up.
I took a count of spans by class (which amounts to a count of tokens by type)
of https://en.wiktionary.org/wiki/Module:languages and came up with:
sy0: 62545 (symbols)
br0: 61952 (brackets)
st0: 39291 (strings)
kw3: 7746 (keywords)
kw1: 3
kw2: 2
co2: 2
co1: 2
nu0: 1
------ ------
Total: 171544
GeSHi allows you to disable highlighting for a particular token type (see
<http://qbnz.com/highlighter/geshi-doc.html#disabling-lexics>) which like a
good way of handling this issue.
Disabling symbols (set_symbols_highlighting(false)) removes both sy0 and br0
elements from the DOM (about 124k elements in the case of Module:languages),
with about 47k elements remaining on the page. This is enough to make Chromium
responsive on my laptop (2.3ghz i5, 8 GB RAM), but it's still noticeably
sluggish. Adding 'set_string_highlighting(false);' removes another 40k elements
from the rendered output, and the resulting DOM is quite zippy at 8k elements.
Proposed solution: disable symbols highlighting when >100 kB; disable strings
highlighting too when >200 kB.

The Geshi rendered output has a font-size of 10px where we would expect
13px just like for <pre>.
Bug 33496 against MediaWiki core dealt with that issue already: in some
(all?) browser 'monospace' has a size of 13px where as the default is
16px. When defining a font-size of 0.8em the monospace is scaled down to
10 px which is too small. By appending another font statement, the
browser treat monospace as a default font and thus scale it starting
with 16px instead of 13px.
This patch append a style to geshi which set the font-family to
"monospace, monospace" thus tricking the browser in considering
monospace a regular font.

This can happen if the TitleIsCssOrJsPage hook causes a page without a
.css or .js extension to be considered a CSS/JS page.

Remove usage of mw-code-inline:
* That class ended up not being merged into core, so it does nothing.
Only mw-code (for the <pre> wrap) is needed.
7c9b2273c9cbdae90c9f4e3890a13619f769c5d0 (mediawiki/core) had both
in an earlier patch version, but only mw-code was merged.
Follows-up:
* mediawiki/extensions/SyntaxHighlight_GeSHi:
dc147a5ef1
Use .mw-code and .mw-code-inline
* mediawiki/core
7c9b2273c9cbdae90c9f4e3890a13619f769c5d0
Add .mw-code styles in core

Also make sure mw-content-ltr/rtl is the same as the dir attribute value. Restrict that value to either ltr or rtl (not sure if rtl really needed; source code is always ltr). Also remove text-align:left; as it can/should be set manually in the <source> tag.
Tidy always converts tabs to spaces on input; on a big <pre> section this is ok but it tends to fail on syntax-highlighted output, where the spacing should depend on the *output* not the *input markup*.
As a workaround, when $wgUseTidy is enabled we now apply our own tab-to-space conversion preemptively on the input before feeding it into GeSHi for highlighting; this keeps the right spacing through to output.
