Commit summary:

* (bug 29140) FirePHP debugging assist extension

FirePHP is an extension to Firebug, an awesome debugging extension to Firefox.
It allows pulling debug log data in from your PHP script via HTTP headers, 
which then get displayed in Firebug's console along with errors, warnings, and 
AJAX hits from the web page.

Added 'Debug' hook which gets called from wfDebug() and wfDebugLog() to take 
this; note that a few lines of output won't make it to FirePHP as they are 
output either before we've done all plugin initialization, or after we've 
flushed output and can no longer add HTTP headers.

BSD-licensed FirePHPCore library from firephp-libs commit aff25803a3ff460b2797:
https://github.com/cadorn/firephp-libs/blob/aff25803a3ff460b2797/packages/core/lib/FirePHPCore/FirePHP.class.php

There's not a lot of fancy integration; everything's just output as a 'log' 
line.
You can use $wgFirePHP global (or call FirePHP::getInstance() yourself) to get 
direct access to FirePHP's fancier features in test code.

Comment:

The addition of wfRunHooks() to wfDebug breaks parserTests and maintenance 
scripts for me.

I have EditUser extension in LocalSettings.php, which require_onces 
GlobalSettings.php precisely in case it is loaded from a maintenance script 
(seems redundant, though).

A different extension triggered the autoloader. The autoloader calls wfDebug 
(if that function exists, which after GlobalSettings inclusion, it does). 
wfDebug calls wfRunHooks which is not declared yet.

We can (and should) fix EditUser, but how many other LocalSettings may have 
such hidden assumption? (and this was a pain to debug)
