When passing an array from PHP to Lua, stringify integer array keys
beyond the range a lua_Number can represent.
When passing a table from Lua to PHP,
* Avoid exponential encoding for integer keys beyond 1e14, so Zend PHP
will interpret them as integers.
* Always encode integer keys as integers, so HHVM will interpret them as
integers.
* Detect collisions, e.g. { [0] = 'foo', ["0"] = 'bar' }

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.

mw.text.unstrip is too broad, it's allowing for unstripping things that

We should also add an interface to StripState::killMarkers(), instead of
requiring everyone to roll their own work-alike.

The LuaStandalone interpreter needs to keep a mapping from integers
returned to PHP to the corresponding function. But if it never releases
these functions when PHP no longer has any reference to them, it can
result in Lua running out of memory if a module with a large number of
functions is invoked many times in one page.
The fix here is to track which function ids are referenced from PHP, and
periodically send the list to Lua so it can remove any that are no
longer used from its cache.
This also takes care of another issue where having multiple interpreter
instances and passing function objects from one into another could call
the wrong function in Lua.
