Add an mw.dumpObject() method, which converts an object in the same manner
as mw.logObject(), but returns it instead of adding it to the log buffer.

Two similar bugs are handled here:
* mw.getCurrentFrame() doesn't work when the module is loaded (only when
a function is called), which breaks os.date and os.time at module
scope since I59ad364d.
* mw.getCurrentFrame() gives access to frame args from inside
mw.loadData, which allows for data leakage between #invokes.

Some functions in mw.html accept numbers as arguments, but later fail when
constructing the string. This disallows numbers in attribute names, since
they aren't valid anyway, and fixes the remainder of the cases to properly
build the string.

Certain wikitext, such as that containing Cite.php <ref> or <references>
or the #tag versions of the same, should not be cached. This uses the
isVolatile method added to PPFrame in I95b3cf87 to avoid caching the

methods.

Rather than calling error() when nils get passed to mw.html methods,
either remove whatever it was that the nil would go to (if that makes
sense), or just do nothing. The seemingly inconsistent use of "not x" and
"x ~= nil" is to allow any falsey value where it wouldn't be ambiguous
(such as class names), but not where it could be (such as attribute values).

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.

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.
