Allow building on FreeBSD

- build shared libraries with major number only (libtt.so.2)
- don't build dtlogin and dtinfo

FreeBSD support for the installer:
- work around awk issue
- create post_install FreeBSD scripts
- install only cmsd on /etc/inetd.conf
  skip dtspc and ttdbserver for now

Note to users: please check
if you are affected by awk bug
in udbParseLib.awk if you can.
