A module for building complex HTML from Lua using a
fluent interface. The module is originally from enwiki,
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.

Apparently this is useful on Commons, where they would like to iterate
over all language names in some of their templates.

This field already exists in PHP with exactly the content requested in
bug 47089, so we may as well expose it on the frame object.

It's already possible to detect whether the current template is being
substituted via ParserFunctions (see [[en:Template:Ifsubst]]), and a
similar trick works with frame:preprocess. So we may as well provide the
flag directly.

Specifically:
* String conversion in non-URL contexts (e.g. .prefixedText) uses spaces
instead of underscores.
* Setting .fragment now applies the same transformations that are done
(in PHP) by mw.title.new.

The following are now correctly escaped:
* Blank lines (including those with only tabs)
* ---- at the start of a line

The following are now correctly escaped:
* Space at the start of a line
* Start-of-line characters after \r
* Magic links such as "RFC 123" with non-space whitespace
* URIs that don't use "://", such as "urn:foo"
* Double-underscore magic words

People have requested a method to log a table as something more detailed
than just "table", to be able to inspect values while debugging.

A few edge cases were being incorrectly handled:
* mw.ustring.sub( 'abc', 1, 0 ) returned 'a', not ''.
* mw.ustring.codepoint( 'abc', 1, 0 ) returned 97, not no results.
* mw.ustring.codepoint( 'abc', 4, 4 ) returned 99, not no results.
* mw.ustring.gcodepoint had the same issues as mw.ustring.codepoint.

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'.

The following errors are fixed:
* PHP warning and wrong return value with empty pattern and plain
* Incorrect offsets returned when init is larger than the string length
* Incorrect captured offsets returned when init is excessively negative

Two related issues:
* The package module was inheriting the loaders from the outer sandbox,
so loaded modules were being loaded into the outer sandbox's
environment.
* mw.loadData was using the outer sandbox's require(), so again loaded
modules were being loaded into the outer sandbox's environment.

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.

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.

This exists for some common text-processing functions that aren't
included in string (and therefore also aren't in mw.ustring), as well as
a logical place for the "unstrip" function requested in bug 45085.

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.

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.

* mw.ustring.sub( '', 1 ) errors in LuaStandalone
* Default value for ustring.maxStringLength and ustring.maxPatternLength
should be infinity, not nil
* mw.ustring.find() returns one value instead of two in "plain" mode.

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.

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.
Change-Id: Icec192bdbe6cfca7902fd5cb5d0e217bd8399637
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".

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.

To allow Lua libraries to mark functions as expensive, add an
incrementExpensiveFunctionCount() method to Scribunto_LuaEngine that
will call the corresponding Parser method and throw an error if the
limit is exceeded.
Also allow libraries to do the same thing from Lua by calling
mw.incrementExpensiveFunctionCount().

Adds a base class for libraries with some utility functions in PHP, and a
Lua library with utility functions for use from Lua.

The listing of the standard modules in package.loaded seems to have been
removed to avoid leaking information to loaded modules. However, since
the *entire* environment is cloned, *including* package.loaded itself,
this does not seem to actually be a problem. But for good measure, also
add a unit test to verify that the version of the standard module tables
referenced from package.loaded is the same as that in _G.
This change also cleans up some unused local variables and an unused
local function from the package module.
