The documentation, and the expectation of users, is that
lang:parseFormattedNumber() should actually return a number, not a
string.

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.

This uses the timezone support added to core Language::sprintfDate in
Iea1f7842 to add support for various timezone-related formatting
characters, and to correct the output for 'c', 'r', and 'U' in local
mode.
This is related to bug 33454, which requests the same for
ParserFunctions' {{#timel:}}.

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.

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.

mw.title.new( pageid ) should not throw an error for an nonexisting
pageid, just return nil. Similarly, it should always return nil for 0,
rather than returning the last non-existent title created.

Every Lua-using page loads the "self" title for mw.title. But we don't
want to record this self-link in the links table, because that confuses
people.

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.

Currently, the time taken to parse the arguments passed to a Lua
function from #invoke will be counted against Lua's 10-second limit.
This is counterintuitive, and can remove incentive for users to convert
templates to Lua since they may have to convert a whole stack at once.
Note this requires change I11881232 to mediawiki/php/luasandbox to
actually have any effect.

People sometimes want to know if the actual file exists, not just the
file description page. Support that.
Also alias .exists to .fileExists for the Media namespace, since that's
what the Media namespace is for.
And while we're at it, fix .exists for special pages too.

* luabit/noki.lua is useless for our purposes
* luabit/utf8.lua is redundant to mw.ustring
* stringtools uses coroutines, which we don't support
Also fix a parser test that has apparently been broken for a long time.

Note that fetching any title besides the one for the current page is
considered "expensive". It also records the title fetched in the
ParserOutput so it will be listed in pagelinks, just like #ifexists.
This also moves the ToString test formatter into TestFramework.lua, so
TitleLibraryTests.lua can use it too.

People sometimes want to load large tables of constant data from a
module. Using require(), this has to be reparsed every time, which can
be slow.
mw.loadData() will load the just data once, and return a table with a
metatable cleverly designed to give read-only access to the loaded data.

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.

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".

The point of putting the unicode library in mw.ustring instead of
ustring was to avoid conflicts with future upstream work, and with other
libraries. It rather defeats the purpose if you then modify the global
string table during module startup.
Users can always set up local aliases if they feel "mw.ustring" is too
much to type.

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.
