For ftp, there's ftp-proxy, and the reverse proxy patch adds support for
servers behind the firewall:
For irc, there's net/tircproxy in the ports tree (which includes a patch
for NAT lookups with pf).
If you write userland proxies for other problematic protocols, they are
welcome. Look at pf(4) and the existing proxies for examples of how to
use pf's ioctl interface. There won't be any application level proxies
in the kernel, and this has indeed been discussed a couple of times, and
google finds the archives :)
