Currently, the only way for PHP to pass a function to Lua is to pass
back a function that it received from Lua. This means, for example, that
PHP cannot implement a Lua iterator function except by registering a
library holding the function or by using loadString.
This changeset adds Scribunto_LuaInterpreter::wrapPhpFunction (and
implements it for both LuaSandbox and LuaStandalone), which takes a PHP
callable and returns a Lua function wrapping it.
Note that fallback code is included so this does not depend on
I2e552799.

The package module is loaded into the "base" environment but not
correctly initialized, so interface modules and the console cannot
actually load anything.

In the debug console, "=unpack( { 1, 2, 3 } )" prints only "1". And
similarly, "mw.log( 1, 2, 3 )" logs only "1". Since Lua uses multiple
return values extensively, this is not particularly helpful.
Following the lead of the lua command-line client, change these to
output multiple values by converting each one using tostring() and then
concatenating them with tab as a separator.

We should include a unit test to try to ensure that we don't add
features to one environment and forget about the other.

There's no reason LuaStandalone cannot handle NaN and Inf.
Also, add some unit tests to check this.

* string.format() truncates the string at a null character, causing a
deadlock when Lua attempts to send null characters to PHP. Use
concatenation instead.
* Added test.
* Fixed an error reporting issue in the console, which I happened to
notice at the same time as the above bug.

If the parser is cloned, we need to give the new instance a new
ScribuntoEngine. Otherwise when one of the clones has ParserClearState
called, the engine for the other will also be unexpectedly destroyed.

All of these were in getScriptTraceHtml, which used some magic ($msgOptions) which is no
longer that easy when using the Message class. As only inContentLanguage ('content') was
used, I documented that, and added the relevant code paths.
I tried to keep the code as readable and brief as possible and also removed an unused
local variable ($linedefined).

Do not try to use the new LuaSandbox class constants in the
backwards-compatible section of the code.

The Darwin does not support POSIX timer which is being used to limit CPU
usage. Running the tests on Mac OS X would never end so we are just
skipping it.

Provide a convenient means to access the current frame so that the
parameter passed to module functions won't need to be conventionally
stored in a global variable.
