[Qemu-devel] [PULL v4 03/38] input: qapi: define event types

[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 a lot 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 split into motion events (one for each axis) and
button events, which are grouped by sync.

Keyboard events are using the existing KeyValue type.
