The wrapper attribute may contain an extra CSS simple selector to
include when prefixing. For example, including a template as
<templatestyles src="..." wrapper="div.my-template"/> would transform
.foo .bar { color:red; }
into
.mw-parser-output div.my-template .foo .bar{color:red}
This can allow particular templates to opt in to the "styles are scoped
to the template itself" model that was desired by some when
TemplateStyles was being designed; the driving use case in the linked
task is doing so for the benefit of side-by-side comparisons of the
current and sandboxed versions of a template.

Two tracking categories are added:
* A category to track stylesheets with errors. While it's usually not
possible to save a stylesheet with errors, it can happen if a
server-side change makes formerly-valid CSS become invalid.
* A category to track pages displaying errors from incorrect use of
the <templatestyles/> tag.

wikimedia/css-sanitizer provides a real CSS parser, which should be
safer than poking at things with regular expressions.
Instead of the strange hybrid model that tried to both process inline
CSS and save CSS when the template is saved, it now looks for
<templatestyles src="Title" /> during the parse to do all the
transclusion of styles.
The output method is "<style> tags in the body", pending someone
implementing T160563.
It now also registers a "sanitized-css" content model, which should pick
up the CSS syntax highlighting and will validate the submitted CSS on
submit and prevent a save if it's not valid.
This patch also takes advantage of LGPL-2.x § 3 to relicense the
extension as GPL-2.0+, although at this point none of the LGPL code
remains anyway.

Depends-On: If4eb5bf71f94fa366ec4eddb6964e8f4df6b824a
- add a tweak to the parser (keep the value tokens in a declaration
separate in the parsed tree to ease matching at render time
- add error checking to encoding/decoding the templatestyles property
- pick some lint suggested by Brion and Bryan

This extension adds a <templatestyles> tag that, when placed
on a template, allows specifying CSS for pages where that
template is transcluded.
Unlike inline styles, the per-template CSS supports rules
with proper selectors, and @media blocks.
THIS VERSION DOES NOT CURRENTLY FILTER DECLARATIONS and is
therefore unsuitable for wikis where unprivileged users should
not be allowed to influcence the pagewide CSS in unrestricted
ways!
