Alexander Jones 1ec95a7bba Accept mw.title object as the title argument of frame:expandTemplate()
This commit fixes an error with using a mw.title object referring to a
mainspace page as the title argument to frame:expandTemplate(), by
adding a leading colon to prevent the function from searching in the
Template namespace.

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.

Jackmcbarn 2b06e83816 Remove message formats other than plain
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
purpose without them.

A module for building complex HTML from Lua using a

but the authors allowed us to reuse it under GPLv2+
(as stated in the file).
The module will be loaded per default and comes with
unit tests.

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.

Brad Jorsch adb7b5f939 Make pairs() work with various library objects
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.

It would be helpful for debugging if a frame object could be gotten in
the console. To that end, add an empty frame when running in the console
and allow it to be returned by mw.getCurrentFrame().

It would also be helpful to be able to create frames with arbitrary
arguments, again for testing. Fortunately support for creating child
frames with arbitrary arguments already exists in core, so we can just
use it.

And for good measure, be sure to restore the $engine->currentFrames
array even if the Lua code throws an exception.

Brad Jorsch 1efe182e40 Hide mw.makeProtectedEnvFuncs from modules
Allowing a module to call mw.makeProtectedEnvFuncs() lets it bypass the
allowEnvFuncs setting. It can also be used to manipulate the global
tables that other modules' sandboxes will be copied from.

And for paranoia's sake, let's tighten up what setfenv is allowed to
set. This requires changing a unit test, because it is no longer
sane to do something like

 env.setfenv, env.getfenv = mw.makeProtectedEnvFuncs( { [env] = true }, {} )

Nothing real does this, it was only in the unit test.

Brad Jorsch 4dcac2fcd9 Fix mw.ustring.gmatch and patterns with '^'
The Lua manual says this:

 For this function, a '^' at the start of a pattern does not work as an
 anchor, as this would prevent the iteration.

I had interpreted that to mean that a pattern starting with '^' would
never match in gmatch. But further testing reveals that the '^' is just
treated as a literal character: string.gmatch( "foo ^bar baz", "^%a+" )
will match "^bar".

Users can always set up local aliases if they feel "mw.ustring" is too

Brad Jorsch 0a8757baba Lua ustring implementation
This is a reimplementation of Lua's string library with support for
UTF-8.

The entire ustring library is implemented in pure Lua. PHP callbacks are
also available for overrides: in LuaSandbox these are used for almost
all functions, while in LuaStandalone they are used only for the pattern
matching. Also, ustring.upper and ustring.lower are overridden using
mw.language's .uc and .lc if available.

It also includes a bunch of unit tests.

Note that if you download the normalization tests, they may fail under
LuaSandbox if you have PHP's intl extension installed and libicu on your
system is too old.
