I was bored. What? Don't look at me that way.
I mostly targetted mixed tabs and spaces, but others were not spared.
Note that some of the whitespace changes are inside HTML output,
extended regexps or SQL snippets.

Extensions that have composer dependencies can set
"load_composer_autoloader": true
to load "$dir/vendor/autoload.php" if it exists.
While it is recommended to use composer-merge-plugin to manage
composer dependencies for extensions, using a local autoloader
can be easier for development and is used by ExtensionDistributor.

This adds a "requires" property to extension.json, which extensions and
skins can use to indicate which versions of MediaWiki core they support.
The hacky wfUseMW() is now deprecated in favor of this.
Rather than writing our own version constraint and parser library, we
can re-use composer's, which was recently split out into a separate
library named "composer/semver" for this patch.
Any syntax accepted by composer[1] is available for usage here. Test
cases have been provided to demonstrate how versions are parsed. For now
it is recommended that people stick to expressing compatability with
stable versions (e.g. ">= 1.26").
This patch does not support requiring specific MediaWiki core WMF
branches, since those do not follow the standard semver format that
composer parses. If we are unable to parse $wgVersion, all checking will
be skipped and reported as compatible.

Versioning the extension.json schema will allow us to make breaking changes
to the schema in a non-breaking manner.
Extensiosn and skins will set a 'manifest_version' value, stating which
version of the schema the file is written for. Processor::extractInfo() will
be passed the version number, and can switch behavior depending upon it.
For backwards-compatability, a version number of 1 is assumed if none is set.
The validateRegistrationFile.php script will emit a warning if this is the
case.

Introduces wfLoadExtension()/wfLoadSkin() which should be used in
LocalSettings.php rather than require-ing a PHP entry point.
Extensions and skins would add "extension.json" or "skin.json" files
in their root, which contains all the information typically
present in PHP entry point files (classes to autoload, special pages,
API modules, etc.) A full schema can be found at
docs/extension.schema.json, and a script to validate these to the
schema is provided. An additional script is provided to convert
typical PHP entry point files into their JSON equivalents.
The basic flow of loading an extension goes like:
* Get the ExtensionRegistry singleton instance
* ExtensionRegistry takes a filename, reads the file or tries
to get the parsed JSON from APC if possible.
* The JSON is run through a Processor instance,
which registers things with the appropriate
global settings.
* The output of the processor is cached in APC if possible.
* The extension/skin is marked as loaded in the
ExtensionRegistry and a callback function is executed
if one was specified.
For ideal performance, a batch loading method is also provided:
* The absolute path name to the JSON file is queued
in the ExtensionRegistry instance.
* When loadFromQueue() is called, it constructs a hash
unique to the members of the current queue, and sees
if the queue has been cached in APC. If not, it processes
each file individually, and combines the result of each
Processor into one giant array, which is cached in APC.
* The giant array then sets various global settings,
defines constants, and calls callbacks.
To invalidate the cached processed info, by default the mtime
of each JSON file is checked. However that can be slow if you
have a large number of extensions, so you can set $wgExtensionInfoMTime
to the mtime of one file, and `touch` it whenever you update
your extensions.
