- Switch to a rc.d startup script.
- Move the generation of the host key (if not present) from the package/
port installation to the startup script in order to be in line with
what the base OpenSSH and the OpenSSH-portable port do.
- Flush stdout when updating the transfer progress bar of sftp2 and scp2
so the info displayed is up to date. 
- Remove obsolete USE_REINPLACE, remove trailing white space in Makefile.
