Use $title->exists() to see if a title exists, and use
$parser->fetchLatestRevisionOfTitle() when available, so that
TemplateSandbox works with title.exists and title.getContent().

If LuaSandboxFunction::call returns false, it's an error on PHP's part.
Throw a "real" exception so that we can see what's causing it in server
logs.

Instead of just displaying "Script error" in wikitext, display the actual
error string. Currently, many users don't see meaningful error messages
generated by modules, and instead just assume that "Script error" means
the module itself has a bug.

Cache patterns and the regexes they become, avoid revalidating the same
pattern multiple times, and don't bother checking if something is a string
when we just made it one.

It's not necessary, it makes the output bigger, and some pages have enough
elements with CSS that it does make an actual difference.

If a function name contains an equals sign, it doesn't increase the index,
so indexOffset=1 makes Lua see arguments as starting with 0. This change
fixes that, so that indexOffset is only set to 1 if the function name has
an index.

When calling getContent() on the page currently being viewed, set
vary-revision on the parser output, as is done when a page transcludes
itself.

In Ia4d58f44, the code enabling __pairs to work no longer ran inside
MWServer.lua, so it hasn't worked right for serialization since then. This
restores the correct behavior.

Add a way to fetch cascading protection information from Lua without
needing to call the CASCADINGSOURCES parser function.

The pure-Lua ustring pattern matching functions short-circuit to the
much faster string library when the pattern would match the same against
the raw bytes.
A pattern like "[^a-z]" can match a partial UTF-8 character when applied
bytewise, and so must be detected as unsafe.
Let's also directly test the pure-Lua module, instead of me having to
comment out lines in Scribunto_LuaUstringLibrary::register() whenever I
want to test them.
