[PATCH 0/7] Improved introspection support and added python demo (v2)

[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.

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.

To introduce the new available bindings, an almost-complete clone of the grilo-test-ui,
written in Python and using introspection for Grilo, Gtk and Gio is being provided.

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.
