Friday Fix Package

A simple drop of the current finished work.

Fixes the disappearing tile syndrome (by working around the misaligned stack pointer which screws up string formatting), crashes due to infinite recursions in gdk_device_dispose, and also has a few additional fixes for utilities like GDB and support for proper profiling on the Pi.

There are a few additional things required in WebKitGTK+ that I still have to test out and properly pack so they can be merged, so I'll be doing another PQ later (today / tomorrow).
