Get rid of liboil

Browse source 
Get rid of the liboil dependency and reimplement the liboil functions with an
equivalent C implementation. Note that most of these functions are deprecated in
liboil and that none of them had  any optimisations. We can further specialize
our handrolled versions for some extra speedups.
