When caching results from frame:preprocess and frame:expandTemplate,
restrict the scope of the cache to the frame object that was used. This
allows the integrity of the empty-frame expansion cache to be maintained
while also allowing parent frame access. This change is the equivalent of
I621e9075 in core.

The new Scribunto_LuaTitleLibrary::redirectTarget() method is
used by mw.title objects as read-only attribute 'redirectTarget'.
If the page does not exist or it is not a redirect, the value
of the attribute is `false`; otherwise, it is the target of the
redirect page, as mw.title object.
This is a proper alternative to parsing wikitext as it is done in:

Lua actually treats a close-bracket at the start of a bracketed

character class. Probably unintended behavior, but it happens.
Also, have the pure-lua version throw our more informative errors on

other weird edge cases that came up in testing.

Marius found a race condition in the handling of SIGXCPU: the pipes
would close, causing the read/write to complete, before the status of
the process changed, so the status would randomly be "running" for a few
milliseconds after proc_get_status() was called.
So: terminate the process unconditionally after an I/O error. Get the
exit status from proc_close(), since that's the only way to get the
status of a terminated process while simultaneously waiting for it to
exit. Also fix signal identification as in unmerged patch I57cdf8aa.

Use cases:
- size: Showing links (like to SVG validator) conditionally (e.g.
only if the filesize is below the threshold it can work on)
- mime: No longer have to guess the MIME type based on the file

precise information about maximum thumbnailable sizes in
case an uploaded work exceeds this limit.
This change will not have negative impact on performance; as soon

At the moment, in mw.site.interwikiMap, URLs stored in the database
with relative protocols are converted to http or https depending
on the protocol of the user who last requested that the page be parsed.
However, this URL isn't updated for users pulling pages from the page
cache, so they may see links with an incorrect protocol. Module authors
can work round this by using mw.uri objects and the isProtocolRelative
property, but it would be simpler just to use relative URLs from the
outset.

This makes the interwiki map available to Lua modules. The code is
based on the API interwiki map code in core (the appendInterwikiMap
method of includes/api/ApiQuerySiteInfo.php.) Everything that the
API includes is added, apart from iw_api and iw_wikiid, which I
couldn't think of a use for from Lua modules.
Accessing the interwiki map would be useful for modules like
enwiki's Module:InterwikiTable,[1] as it would stop module writers
having to duplicate the data.

mw.text.unstrip is too broad, it's allowing for unstripping things that
cause problems when unstripped (e.g. bug 61268). Since the original
request was only for unstripping <nowiki>, let's add a function that
does only that.
We should also add an interface to StripState::killMarkers(), instead of
requiring everyone to roll their own work-alike.
Then, to fix the bug, we can make mw.text.unstrip be the combination of
the two. This is the most like the original behavior of mw.text.unstrip
(removes all strip markers, replacing them with text where applicable)
without causing issues.

The pure-Lua ustring pattern matching functions short-circuit to the

A pattern like "[^a-z]" can match a partial UTF-8 character when applied
