We cannot avoid this, we can only encapsulate behavior in wrapper
functions, the reason is that MIT and Heimdal have some basic data types
that differ, and other funny things, so there is really no way around

Hopefully we will be able to avoid most of it by creating pluggable
backends in GENSEC, so that most of what we need will be abstracted away
from most of the code, but some of it will always be around I am afraid.

Features detection is ok to weed off older versions, but for API
incompatibility there isn't much we can do.
