* Magic links such as "RFC 123" with non-space whitespace
* URIs that don't use "://", such as "urn:foo"

Current logic is to display the funciton name if Lua provides us with
one, "main" if it's at the main level, or "?" if it's a C function or a
tail call. But we're not handling if it's a Lua call but Lua can't guess
a name for the function; use "?" for that too.

If the user is on a webhost that has proc_open listed in PHP's
disable_functions directive, we should give a better error message.
Until we no longer support PHP below 5.4, we should do the same for
safe_mode. And since we're doing that, we may as well report any other
warnings if proc_open fails, too.
In addition, this cleans up error handling in
Scribunto_LuaEngine::load() so it doesn't pretend the interpreter is
loaded if getInterpreter() throws an exception. Otherwise other code
winds up with PHP fatal errors trying to access a null value.

If the parser function returns 'isChildObj', we need to create a child
frame to expand the wikitext returned by the parser function. And when
we pass the arguments to the new frame, we need to pass them through the
preprocessor's newPartNodeArray() first.

Users seem to expect that mw.language's parseFormattedNumber will act
like tonumber when given nil or other non-string values, returning nil
instead of raising an error. There's no reason not to, so we may as
well.

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.

Negative values for 'i' in mw.ustring.byteoffset are supposed to count
from the end of the string. But in LuaSandbox, it was actually counting
from two bytes before the end of the string due to a typo.
Fix that, and add some tests for it.

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'.

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.

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.

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.
