[gnome-builder/wip/libide] libide: start on IdeGcaService

[Christian Hergert <chergert src gnome org>]

commit 2f3bfde2d8791717655e2d5052acce5656ad2c25
Author: Christian Hergert <christian hergert me>
Date:   Sat Feb 14 21:35:33 2015 -0800

    libide: start on IdeGcaService
    
    This service will help us manage connecting to GCA and providing proxy
    structures. Doing so will allow us to progress towards creating an
    IdeGcaDiagnosticsProvider. Once that is in place, we basically have
    everything we have today in src/gca, but with the ability to bring some
    parts in process (like clang).
