[PATCH v1 3/6] vt/vt: Enable mode change via escape sequence

[Tammo Block]

This enables userspace to enable one of the mouse protocols and choose
one of the new event types by escape sequences.

They are not a bitmasks, but mutually exclusive.

And don't forget to reset protocol value also if resetting vc.
