d0cd6ba47d extensionSystem: fix runtime enable()/disable() after last changes
disableExtension still used the old way to retrieve the state object,
and enableExtension called loadExtension at a time that would
always fail.

a622aba7eb extensionUtils: Create and allow access to a new "extension" object
The "extension" object is what I previously called the "helper" object.
It contains the extension importer object as well as the metadata object.
Things that were previously added on to the metadata (state, path, dir, etc.)
are now part of this new "extension" object.

With the new importer changes brought on by the extension prefs tool,
extensions are left without a way to import submodules at the global scope,
which would make them rely on techniques like:

  var MySubModule;

  function init(meta) {
      MySubModule = meta.importer.mySubModule;
  }

That is, there's now a lot more meaningless boilerplate that nobody wants
to write and nobody wants to reivew.

Let's solve this with a few clever hacks.
Allow extensions to get their current extension object with:

  let extension = imports.misc.extensionUtils.getCurrentExtension();

As such, extensions can now get their own extension object before the
'init' method is called, so they can import submodules or do other things
at the module scope:

  const MySubModule = extension.imports.mySubModule;
  const dataPath = GLib.build_filenamev([extension.path, 'awesome-data.json']);

80ff6ff797 Move a lot of miscellaneous code related to extensions into a new module
ExtensionUtils is a new module that has a lot of miscellaneous things related
to loading extensions and the extension system put into a place that does not
depend on Shell or St.

Note that this will break extensions that have with multiple files by replacing
the old uuid-based importer with an object directly on the meta object.

2f27b94757 extensionSystem: Fix an error related to extension importing
If an extension fails to import, we will pass the error object
to logExtensionError, which fails to pass it onto DBus as an
error object is not a string. To fix, convert the error object
to a string before passing it to logExtensionError.

bbb83656bf extensionSystem: Set the proper 'enabled' and 'type' parameters
When installing an extension at runtime, we accidentally swapped the 'type'
and 'enabled' parameters. While this doesn't directly affect anything right
now, as everything works coincidentally, future patches that look at the
'type' parameter to decide what to do would get the wrong answer.

fd1b3b4fee extensionSystem: Rebase the extension order list to help prevent conflicts
When two extensions monkey-patch the same area, enable() and disable() may
behave badly and completely wreck things. To solve this, when disabling
an extension, "rebase" the extension list so that monkey patches should be
added and removed in order.

This adds a new DBus method: InstallExtensionRemote(uuid : s, url : s)

Pass it the UUID of an extension and the URL of a manifest file: the same as a
metadata.json, but with a special key, '__installer', which is an HTTP location
that points to an zip file containing the extension. The Shell will download
and use it to install the extension. In the future, the manifest file may be
used to automatically detect and install updates.

2799327c84 Migrate to GSettings
Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.

A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.

GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

This is our convention.

The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
of the output string.

aa9d3515a1 Add extensionSystem
Consumer documentation will live at http://live.gnome.org/GnomeShell/Extensions

In terms of implementation; basically we load extensions from the well-known
directories.  Add a GConf key to disable extensions by uuid.  There is a new
option --create-extension for the gnome-shell script which takes a bit of
interactive input, sets up some sample files, and launches gedit.

No extensions UI in this patch; that will come later.
