XI2: Split up raw events into multiple event types.

Browse source 
Instead of a single XI_RawEvent type with subtypes to represent the actual
event, split up the event into XI_RawButtonPress, XI_RawButtonRelease, etc.
This way clients can select for specific raw events only instead of all of
them at once.

Note that raw events may be selected on master devices too, the server will
route them through master devices.

A RawDevice event provides the information provided by the driver to the
client. RawDevice events are only generated for slave devices and provide
both the raw data as supplied by the driver and transformed data as used
in the server. Transformations include, but are not limited to, axis
clipping and acceleration.
