[channels.c channels.h clientloop.c nchan.c nchan.h serverloop.c ssh.c] move to Channel **channels (instead of Channel *channels), fixes realloc problems. channel_new now returns a Channel *, favour Channel * over channel id. remove old channel_allocate interface.

[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@

[buffer.c channels.c channels.h readconf.c ssh.c] allow the ssh client act as a SOCKS4 proxy (dynamic local portforwarding). work by Dan Kaminsky <dankamin@cisco.com> and me. thanks to Dan for this great patch: use 'ssh -D 1080 host' and make netscape use localhost:1080 as a socks proxy.
