I252ec046 noticeably broke things by adding a dependency on the pcntl
functions, which tend not to be present under Apache.
It also subtly broke exit handling by using proc_close()'s return value,
which PHP mangles in such a way that we can't tell the difference
between an actual XCPU kill and exit( SIGXCPU ). This one wasn't noticed
because the pcntl functions interpret everything proc_close() is going
to return as a signal kill and we didn't test the 'exited' code path.
I'm not sure what was going on in I57cdf8aa since it provides no details
about what it was trying to fix, but that would have broken signal
handling in the other way: Ibf5f4656 worked because proc_open() on Linux
executes the command by passing it to /bin/sh -c, and that shell is
going to turn any signal that kills Lua (e.g. the SIGXCPU) into an exit
status of 128+signum.
To avoid proc_close()'s broken return value while also avoiding the
race, we can loop on proc_get_status() until $status['running'] is
false.
To have signals that kill Lua actually be interpreted as signals, we
have two options: add an "exec" in front of the command so proc_open()'s
/bin/sh -c is execed away, or detect shell-style signal reporting and
convert it. We may as well do both.

normalization-data.lua is updated to Unicode 6.3.0.

https://www.mediawiki.org/wiki/Extension:Scribunto says that master
requires 1.25+, so let's remove checks for stuff that was added before
that.
* PPFrame::getTTL() was in 1.24.
* PPFrame::setTTL() was in 1.24.
* PPFrame::isVolatile() was in 1.24.
* Parser::fetchCurrentRevisionOfTitle() was in 1.24.
* ObjectCache::getLocalServerInstance() was added in 1.27, so restore the call to ObjectCache::newAccelerator() as BC.
This also removes BC with the php-luasandbox extension older than 1.6, which
was released before MediaWiki 1.22.

An empty pattern isn't "safe" since it could match in between the
bytes of a UTF-8 character.
Also, it turns out there's a bug in PHP <5.6.9 preg_replace() that we
need to work around too.

For the PHP implementation, return the codepoints as a table instead of
multiple return values that get table-ified in Lua, to avoid hitting
too-many-values stack limits.
For the pure-Lua version, inline most of ustring.codepoint instead of
calling it to avoid what's effectively "{ unpack( stuff ) }".

mw.ustring is really really slow. I've discovered that in a lot of modules
on enwiki, upwards of 2/3 of the total runtime gets used when mw.html
calls mw.ustring.gsub. This change checks whether any Unicode characters
are present, and if not, calls string.gsub instead.

Core strip markers were changed in T110143 to include characters that

The following continue to be ignored:
* Generic.Arrays.DisallowLongArraySyntax.Found, because I'm not sure
Scribunto is ready to abandon old version support in master.
* MediaWiki.ControlStructures.AssignmentInControlStructures.AssignmentInControlStructures,
because it's overly strict for its purpose.
Squiz.Classes.ValidClassName.NotCamelCaps isn't ignored globally, we
just ignore it explicitly every place it's needed.

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 as a literal, rather than using it to close the
character class. Probably unintended behavior, but it happens.
Also, have the pure-lua version throw our more informative errors on
error even when falling back to string.find and the like, and fix some
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.

This is apparently unofficially deprecated, and we can do things a bit

This also takes the opportunity to move "ext.scribunto", which is mostly
