[channels.c channels.h servconf.c servconf.h serverloop.c sshd.8]
Add options ClientAliveInterval and ClientAliveCountMax to sshd.
This gives the ability to do a "keepalive" via the encrypted channel
which can't be spoofed (unlike TCP keepalives). Useful for when you want
to use ssh connections to authenticate people for something, and know
relatively quickly when they are no longer authenticated. Disabled
by default (of course). ok markus@

allow the ssh client act as a SOCKS4 proxy (dynamic local

thanks to Dan for this great patch: use 'ssh -D 1080 host' and make
netscape use localhost:1080 as a socks proxy.
