[gnome-builder/wip/chergert/bug1: 9/42] gdb: add gdb based debugger implementation



commit d6f0a64c851b11facb3d697f5dc516235e8b8235
Author: Christian Hergert <chergert redhat com>

    gdb: add gdb based debugger implementation
    
    This is a fairly minimal implementation. There is plenty more we can do
    as we extend the IdeDebugger API for things like variable hover,
    visualizers, and more.

+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
