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.

If someone puts something broken in MediaWiki:Scribunto-doc-page-name,
it may not be possible to determine which module the page is a doc page
for. In that case, just pretend it's not a doc page.

If the interpreter exits before the end of the page, then the call to
Scribunto_LuaStandaloneEngine::getLimitReport() throws an uncaught
exception when it tries to access the interpreter. Catch 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'.

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

We had intended to use the constant CONTENT_FORMAT_TEXT, but
accidentally used that as a string instead.

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.
