getParser() sometimes returns null (eg: on saving edits). In that case,
don't try injecting link information into the (non-existent)
ParserOutput object.

Clean up the modules in engines/LuaCommon/lualib:
* Fix luabit/bit.lua to return its table instead of trying to set the
global directly.
* Fix luabit/hex.lua to return its table instead of trying to set the
global directly.
* 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.

In phpunit 3.6.10, assertEquals considered two NaNs to be equivalent.
Somewhere between that and phpunit 3.7.14, this behavior changed so NaNs
are no longer considered equivalent.

Add the ability for modules to be documented using a /doc subpage, which
is automatically transcluded onto the module page.
To get the transcluding to work right, I wound up having to change from
the deprecated-in-1.21 ArticleViewCustom hook to ContentHandler, as
there didn't seem to be any other way to get the ParserOutput into the
links tables. Which means Scribunto now needs MediaWiki 1.21 rather
than 1.20.

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.

Subpages should probably be enabled by default for the Module namespace,
considering that we're planning on using /doc subpages for
documentation.

Otherwise there is a circular reference and the engine is not destroyed

Added a language library. Introduced functions which are easy and safe,
most of them already have parser function interfaces.

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".

Wikidata has already requested the ability to add libraries into Lua. We
do this in a simple way: add a $wgScribuntoExtraLibraries global, and
load whatever modules someone puts there.

It's easy to forget a 'local' somewhere and accidentally leak a global
variable. Add a unit test to catch that.

Fixed several accidental leaks to the global namespace due to missing
"local" declaration. Removed extension of the string table by mw.uri,
same justification as I5d0ddb70.

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.
