ac9a4c839f Add -c <command> option to force a specific command 
This change adds a -c option to dropbear, to force the session to use a
specific command, in a similar fashion to OpenSSH's ForceCommand
configuration option.

This is useful to provide a simple fixed service over ssh, without
requiring an authorized key file for the per-key forced_command option.

This setting takes precedence over the channel session's provided
command, and the per-key forced_command setting.

dc01a8edd4 Don't display the MOTD when an explicit command is run. 
(possibly via authorized_keys(5) restrictions), even when a
pseudo-terminal has been allocated for the session.  In other words,
only display the MOTD when the server starts the user's default shell.

da57dd13c5 Set tcp priority as follows: 
if (connecting || ptys || x11) tos = LOWDELAY;
else if (tcp_forwards) tos = 0;
else tos = BULK;

TCP forwards could be either lowdelay or bulk, hence the default priority.
