(Note from Andy:
 For now, these are stubs.  The rest of the comments reflect my ideas

These are routines unique to VSTa for accessing the mouse and keyboard.

The mouse access uses the existing mouse server.

The keyboard access is emulated by way of POSIX TTY I/O routines.
This means that the kinds of events which can be generated is limited
to the usual character typing; key up events as well as key down for
modifiers (like shift) are not possible.
TBD: add support for the additional events to the console server.
