ifconfig.if rtsol autoconf diff

[Tim Kuijsten]

Had some trouble this morning in configuring inet6 on a new laptop. 
Finally figured out that rtsol is dropped and that the functionality is 
moved to the kernel. Diff for hostname.if(5) included. Someone might 
want to replace the "rtsol" keyword in the installer as well.

 Also note that the kernel must be configured as a host (i.e. non-router).
