This works, but is pretty ugly.
Doesn't GLib has functions to ensure retrieve unaligned data? BlueZ has
the GCC magic that is required to do this right.
I have looked everywhere for something nice from glib, but I'm not
seeing it. As far as I can tell, most people just do the bit shifting
manually -- but that's what I had originally and you didn't like it.
So I'm only seeing 2 options here, this way or the original way. If
you know of the glib function to use, please let me know what it is.
