Arkadiusz Miśkiewicz fadca8ad77 Better method of figuring out v1 vs v2 protocol version. 
Protocol version detection isn't very reliable (especially for
hid++ v1).

Version 1 checking was potentially happening in every hidpp_device_cmd()
call and not only when requested. Improve that to do version checking
and priv->version manipulation only when requested by using
HIDPP_REFRESH_FLAGS_VERSION.

When doing version checking first try v2 protocol command and if it
succeeds assume version 2 device. Otherwise try v1 protocol query
and if that successds assume version 1 device.

v2 devices in unreachable/sleep mode seem to do not respond to v2
queries but they respond to v1 queries! Still we want best protocol
possible. To do that we are rechecking version when current protocol
version is below 2 and we are doing up_device_unifying_refresh() and if
recheck succeeds we upgrade protocol to v2.

UPower is an abstraction for enumerating power devices,
listening to device events and querying history and statistics.
Any application or service on the system can access the
org.freedesktop.UPower service via the system message bus.
