Minor bug in HostbasedAuthentication

[Carson Gaspar]

When using "HostbasedUsesNameFromPacketOnly yes", the ssh client sends the 
hostname with a trailing dot, but the server does not strip off the 
trailing dot when matching against .shosts et. al., or when looking up keys 
in ssh_known_hosts2. This causes the host to not be found. Adding the 
hostname with trailing dot to the config files "fixes" this, but I think 
sshd should do this itself.

If you like, I can try to gen a patch. I thought I'd ask first, in case 
major restructuring was going to occur in this code.
