Jackmcbarn fd9ecb9cbe Expose cascading protection directly to Lua
Add a way to fetch cascading protection information from Lua without
needing to call the CASCADINGSOURCES parser function.

Brad Jorsch 0367e9bddd Fix deceptively-simple pattern in pure-Lua ustring
The pure-Lua ustring pattern matching functions short-circuit to the
much faster string library when the pattern would match the same against
the raw bytes.

A pattern like "[^a-z]" can match a partial UTF-8 character when applied
bytewise, and so must be detected as unsafe.

Let's also directly test the pure-Lua module, instead of me having to
comment out lines in Scribunto_LuaUstringLibrary::register() whenever I
want to test them.

Brad Jorsch 85aca87e94 Improve mw.getCurrentFrame handling
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.

Jackmcbarn 8d1d5ac84c Fix strange mw.html errors with numeric arguments
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.

Jackmcbarn d1030989bc Allow passing nils to mw.html
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).

Brad Jorsch 708d87c181 Prevent passing information between #invokes using math.random
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.

Brad Jorsch 82820aafc8 Add frontier pattern (%f[set]) to ustring
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'.

Brad Jorsch 581b2306af Remove mw.getLogBuffer and others from public interface
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.

Users are reporting disappointment that using pairs on title objects
doesn't let them see the fields available. It's easy enough to add a
__pairs metamethod to allow pairs to work on title objects, so let's do
that.

The same can be done for mw.uri objects.

For mw.message objects, we can easily enough change the implementation
to be like mw.language objects, which doesn't have this problem.

For mw.site.stats, we may as well just remove the load-on-demand feature
since it will be demanded as soon as the environment is cloned for the
first module.

use it.

And for good measure, be sure to restore the $engine->currentFrames
