[PATCH 00/17] Improved introspection support and added python demo

[Simón Pena <spenap gmail com>]

Hi,

The following patches improve introspection support by completing
the annotations for grl-plugin-registry, grl-media-source, grl-multiple
and grl-data

Besides, two functions have been added to grl-metadata-key exposing
functionality previously accessible only via macros, to get keys' name
and description.

The rest of the patches provide a small Python test showcasing a media search
and an almost-complete clone of the grilo-test-ui, written in Python and
using introspection bindings for Grilo, Gtk and Gio.

These patches annotate 'GrlKeyID's as 'GObject.ParamSpecs*'. While they are
fully supported in Python, they aren't yet in JavaScript (see bug #626047).
Besides, callbacks' GErrors have been annotated as uints.

Once this patches get accepted, I'll update Grilo's bug #616961, notifying of
this progress, and submitting a workaround to access our metadata keys from
JavaScript (by annotating the keys as uints), and the JavaScript test updated.
