For security, we would like to monitor and track when the thunderbolt
devices are authorized and deauthorized (i.e. when the thunderbolt sysfs
"authorized" attribute changes). Currently the userspace gets a udev
change notification when there is a change, but the state may have
changed (again) by the time we look at the authorized attribute in
sysfs. So an authorization event may go unnoticed. Thus make it easier
by informing the actual change (new value of authorized attribute) in
the udev change notification.
The change is included as a key value "authorized=<val>" where <val>
is the new value of sysfs attribute "authorized", and is described at
Documentation/ABI/testing/sysfs-bus-thunderbolt under
/sys/bus/thunderbolt/devices/.../authorized

I did some tiny changes to the title, commit message and the comment and
applied to thunderbolt.git/next, thanks!
