goldfish: tty driver
This provides a console driver for the Goldfish virtual platform. The original is from Arve with changes from Jun Nakajima and Tom Keel. This has been then been ported to the current kernel and to the tty port mechanism by Alan Cox. In the process it gained proper POSIX semantics and vhangup works. The default name is not ttyS as this belongs to the 8250 driver. Instead ttyGFx is now used. In the normal usage case the first port serves as a kernel logging console and the second one carries various other data streams for the emulation.
