Allow guest serial port to redirect to a pseudo terminal on UNIX hosts

Currently you can redirect a guest's serial port only to a domain socket or a hardware port (TTY). Connecting to a domain socket requires additional tools like "socat" to transform the vbox domain socket to either a PTY or TCP port.

It would be nice to be able to redirect a guest's serial port *directly* to a pseudo terminal slave device on UNIX hosts. Basically I would like to do something like:

VBoxManage--uartmode1 /dev/ttyp1
screen /dev/ptyp1 && VBoxManage startvm linux

On v 4.1. this fails with Failed to open host device /dev/ttyp1 VERR_RESOURCE_BUSY

A forum thread describing this issue:

I hope adding this is not too difficult since you already support TTYs. Thanks.
