On my test system, ScriuntoHooks::invokeHook takes about 4 seconds of
CPU time during the parse of a page containing 1000 #invokes of a module
containing a single do-nothing function. And about 2.3 of those seconds
appear to be spent in ScribuntoEngineBase::fetchModuleFromParser.
ScribuntoEngineBase::fetchModuleFromParser already assumes that if
Parser::fetchTemplateAndTitle returns the same $finalTitle then $text is
also the same and we can reuse the same module. But it seems just as
likely that the same input $title is always going to give the same
$finalTitle, so we may as well skip calling
Parser::fetchTemplateAndTitle entirely if we've seen the input $title
before.
This change takes the CPU time spent in ScriuntoHooks::invokeHook in the
test described above down to about 1.5 seconds. And since it's very
likely that $title and $finalTitle are the same (Modules don't support
redirects, so it's basically TemplateSandbox that would cause that), it
probably doesn't even increase the size of the module cache.

Every Lua-using page loads the "self" title for mw.title. But we don't
want to record this self-link in the links table, because that confuses
people.

It has been claimed that some wiki might want to place module
documentation at a location other than as a subpage of the module, for
example under "Project:Module documentation/$1". It's possible to
support this, so we may as well.
This also involves renaming the "scribunto-doc-subpage-*" messages to
"scribunto-doc-page-*", since the interpretation of
scribunto-doc-subpage-name would be drastically changed.
Note that any wiki that has customized scribunto-doc-subpage-name will
need to re-customize scribunto-doc-page-name, the old value will not be
transferred.

It would be helpful for debugging if a frame object could be gotten in
the console. To that end, add an empty frame when running in the console
and allow it to be returned by mw.getCurrentFrame().
It would also be helpful to be able to create frames with arbitrary
arguments, again for testing. Fortunately support for creating child
frames with arbitrary arguments already exists in core, so we can just
use it.
And for good measure, be sure to restore the $engine->currentFrames
array even if the Lua code throws an exception.

Currently, the time taken to parse the arguments passed to a Lua
function from #invoke will be counted against Lua's 10-second limit.
This is counterintuitive, and can remove incentive for users to convert
templates to Lua since they may have to convert a whole stack at once.
Note this requires change I11881232 to mediawiki/php/luasandbox to
actually have any effect.

The Scribunto "Script error" can be clicked, which is indicated by a CSS
cursor:pointer style. To make it more discoverable, also have it show an
underline on hover (as links do by default).
And while we're messing with it, let's remove that "style" attribute and
use the already-existing CSS class to assign the styles.

People sometimes want to know if the actual file exists, not just the
file description page. Support that.
Also alias .exists to .fileExists for the Media namespace, since that's
what the Media namespace is for.
And while we're at it, fix .exists for special pages too.

Since the content of a page is being loaded, this should be recorded in
templatelinks so things can be updated properly when that page is
edited.

In the unit tests, the engine is given a parser, but the parser is not
being associated back with the engine. So in some cases, that could lead
to *another*, default engine being created for certain operations.
Fix that.

Apparently assigning to $wgHooks at the top of the file breaks every
other hook, somehow. So we need to set it in setUp(), but prevent the
interwiki prefix from being queried beforehand when the dataProvider is
run. Fun.

* mw.ustring.sub( '', 1 ) errors in LuaStandalone
* Default value for ustring.maxStringLength and ustring.maxPatternLength
should be infinity, not nil
* mw.ustring.find() returns one value instead of two in "plain" mode.
