[Qemu-devel] [RFC PATCH 03/15] input: define event types using qapi

[Gerd Hoffmann]

Define input event types, using qapi.  So we get nicely autogenerated
types for our input events.  And when it comes to qmp support some day
things will be alot easier.

Types are modeled after the linux input layer.  There are separate
event types for each value.  There is a sync to indicate the end
of a event group.

Mouse events are splitted into motion events (one for each axis) and
button events, which are grouped by sync.

Keyboard events are using keycodes instead of scancodes, so we can
rid of the keycode->scancode transformation everywhere in the
ui code.
