* replace union sockunion {} with struct sockinet {}, and modify the code
accordingly. this is possibly more portable, as it doesn't rely upon
the structure alignment within the union for our own stuff. uses local
su_len unless HAVE_SOCKADDR_SA_LEN is defined (set ifdef BSD4_4)
(XXX: haven't tested the ipv6 stuff)
* always use getaddrinfo() and getnameinfo() instead of maintaining two code
paths. (lukemftpd will provide replacements for these on older systems)
* use lockf() instead of open(.., O_EXLOCK) to lock the pid file
* minor KNF
* clean up long long support: create helper #defines and use as appropriate:
#define NO_LONG_LONG ! NO_LONG_LONG
