It's possible to pass information between multiple #invokes on a page by
having the first call math.randomseed with one of a set of known seeds
and then having the second examine the output from math.random to
determine which of those known seeds was used.
Prevent that by calling math.randomseed( 1 ) when invoking (see the bug
for details on why that seed). But avoid doing so if e.g. a
frame:expandTemplate() call results in a recursive invoke.

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.

Message formats other than plain should have never been exposed in this
way, as they allow link tables, etc. to be bypassed and serve no useful
purpose. This removes them, and also removes title, as it serves no

PHP can't handle having arrays/objects or functions as keys in its
arrays, so make sure we don't try to pass them from Lua. Booleans aren't
really well-handled either, so let's disallow them too.
Also, add tests for proper stringification of floats and infinities when
those are used as keys.
Note this behavior change is needed to match the change in LuaSandbox
for fixing bug 54527, but isn't itself a security issue.

Current logic is to display the funciton name if Lua provides us with
one, "main" if it's at the main level, or "?" if it's a C function or a
tail call. But we're not handling if it's a Lua call but Lua can't guess
a name for the function; use "?" for that too.

The binaries currently provided were compiled against glibc 2.11+, so
people using CentOS 5 (which has glibc 2.5) are not able to use them.
The binaries in this patch were compiled in VMs installed with CentOS

glibc 2.3 or later will probably work now.

If the user is on a webhost that has proc_open listed in PHP's
disable_functions directive, we should give a better error message.
Until we no longer support PHP below 5.4, we should do the same for
safe_mode. And since we're doing that, we may as well report any other
warnings if proc_open fails, too.
In addition, this cleans up error handling in
Scribunto_LuaEngine::load() so it doesn't pretend the interpreter is
loaded if getInterpreter() throws an exception. Otherwise other code
winds up with PHP fatal errors trying to access a null value.

The "%f[set]" frontier pattern has been in Lua 5.1 since the beginning,
but was undocumented until Lua 5.2. And the code is even unchanged from
5.1.0 to 5.2.1. So there's no reason not to implement it in ustring too.
Note the changes to UstringLibrary.php are somewhat large, because it
splits the "convert a Lua bracketed charset to PCRE" code into a
separate function and it changes the handling of mw.ustring.find's and
mw.ustring.match's 'init' parameter from "substring, match from 0, then
add back on $init" to "use preg_match's $offset and use \G instead of ^
where this matters". Both of these are necessary to properly support
%f.
This also fixes a bug in the pure-Lua code (not used in Scribunto)
exposed by the unit tests for %f where %z was matching '\1' rather than
'\0' and %Z everything except '\1' instead of everything except '\0'.

One of the design goals of Scribunto is that each #invoke should be
independent. Creative use of mw.log and mw.getLogBuffer can get around
this, passing information from one #invoke to the next.
This patch takes the simple solution of removing mw.getLogBuffer from
modules' environments. For good measure, it also removes
mw.clearLogBuffer and mw.executeModule.
Some minor cleanup of the console code is also included.

On Windows for LuaStandalone, the lua executable's standard output is a
text-mode file handle, even if the pipe is opened from PHP with the
binary flag. Which means that when Lua returns a "\n", it gets silently
rewritten to "\r\n" and the unserialization fails.
So, change the protocol for Lua→PHP messages to encode \r and \n (and \
itself, as the escape character) to avoid this issue.
