This structure will eventually contain a list of NCPs (currently
only IPCP is supported) and a list of physical `struct link's.
It will also derive from a struct link itself.
Make ModemTimeout() static - it's way to dangerous to be called

Bump version to 1.9. Our first MP release should be 2.0.
o Take note of the return value of the compression layers
init routine, and if it fails, bring the whole layer
cleanly back down again.
o Only use srandomdev() if ``__FreeBSD__ > 2'' - this makes
these sources buildable on 2.2 (where I'm testing).
