Bug #3440: Notify applications when a display connection changes
http://bugs.dragonflybsd.org/issues/3440#change-14780

* Author: sigttou
* Status: Resolved
* Priority: Normal
* Category: Driver
* Target version: 6.6

----------------------------------------
DisplayPort audio can remain silent after a monitor sleeps, is turned off,
and reconnects. DragonFly does not notify applications such as Xorg about
the connection change, so they can retain outdated display and audio state.

Send a notification when the display connection changes so applications
can refresh that state. This uses the notification already provided by
FreeBSD drm-kmod.
