Clarify semantics of c->v4 and c->v6 variables
The v4 and v6 fields of the context structure can be confusing, because
they change meaning part way through the code: Before conf_ip(), they are
booleans which indicate whether the -4 or -6 options have been given.
After conf_ip() they are DISABLED|ENABLED|PROBE enums which indicate
whether the IP version is available (which means both that it was allowed
on the command line and we were able to configure it). The PROBE variant
of the enum is only used locally within conf_ip() and since recent changes
there it no longer has a real purpose different from ENABLED.
Simplify this all by making the context fields always just a boolean
indicating the availability of the IP version. They both default to 1, but
can be set to 0 by either command line options or configuration failures.
We use some local variables in conf() for tracking the state of the command
line options on their own.
