Rework TTY column

* Rename internal identifier from TTY_NR to just TTY
* Unify column header on platforms
* Use devname(3) on BSD derivate to show the actual terminal,
  simplifies current FreeBSD implementation.
* Use 'unsigned long int' as id type, to fit dev_t on Linux.

Only on Solaris the terminal path is not yet resolved.
