o merge listen patch
o merge IPv6 patch (maybe not, noone can test it)
o solve licensing issues
o random stuff to check:
	- check all snprintf, memset, memcpy, strncat functions
	- check loops over pointer (*ch++ stuff) without checking *p
	- check why the implicit '(int) (p-buf);' needs to be done in findline()
	- check if we can get rid of these strange 'register int ...'
	  declarations
	- check global pointer *pr00gie below paramtoken
	- check returnvalue of readwrite and improve, so no hanging fd's will be
	  passed to shout()!
	- check coredump when connecting to ssh daemon, writing some bytes and
	  CTRL+C it.
	- check code for malloc()/missing free()
o fix code for SO_[REV|SND]BUF which is commented right now. We really want to
  enable it.
o take out stupid reverse lookup
o standardize use of error checking. either perror or fprintf(stderr..)
o add packet counter
o add raw socket support
o add support for tcpd and hosts.allow ?
