script(1): Sync with FreeBSD

- Add -p flag which is used to replay typescripts.
- Add -d flag to avoid sleeps in playbacks.
- Add -F flag which allows recording/playing through pipes.
- Add -r flag to optionally record all.
- A bunch of fixes, mostly.

Note: -f flag from FreeBSD is not available since DragonFly BSD does not
have filemon(4)
