Brad Jorsch 8e6e07c75f Handle backtrace where Lua can't guess the function name
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.

Brad Jorsch 5a9b7cc5a6 More-compatible Linux standalone binaries
The binaries currently provided were compiled against glibc 2.11+, so
people using CentOS 5 (which has glibc 2.5) are not able to use them.

The binaries in this patch were compiled in VMs installed with CentOS
5.9, and so should work for more people; at a glance, it looks like
glibc 2.3 or later will probably work now.

Brad Jorsch c7246a1c42 Improve disable_functions handling in LuaStandalone
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.

well.

Negative values for 'i' in mw.ustring.byteoffset are supposed to count

from two bytes before the end of the string due to a typo.

Brad Jorsch 82820aafc8 Add frontier pattern (%f[set]) to ustring
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'.

Brad Jorsch 581b2306af Remove mw.getLogBuffer and others from public interface
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.

Brad Jorsch 71d9f600dc (bug 46294) Fix for Windows text-mode file handles
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.

Brad Jorsch adb7b5f939 Make pairs() work with various library objects
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.
