Despite all the careful planning of the kernel, a link may become
insufficient to handle the currently-set mode. At this point, the
kernel should mark this particular configuration as being broken
and potentially prune the mode before setting the offending connector's
link-status to BAD and send the userspace a hotplug event. This may
happen right after a modeset or later on.
Upon receiving a hot-plug event, we iterate through the connectors to
re-apply the currently-set mode on all the connectors that have a
link-status property set to BAD. The kernel may be able to get the
link to work by dropping to using a lower link bpp (with the same
display bpp). However, the modeset may fail if the kernel has pruned
the mode, so to make users aware of this problem a warning is outputed
in the logs to warn about having a potentially-black display.
This patch does not modify the current behaviour of always propagating
the events to the randr clients. This allows desktop environments to
re-probe the connectors and select a new resolution based on the new
(currated) mode list if a mode disapeared. This behaviour is expected in
order to pass the Display Port compliance tests.

We were adding entries at the start of the list, i.e. the list was
ordered from most recently added to least recently added. However, the
corresponding DRM events are generally expected to arrive in the same
order as they are queued, which means that radeon_drm_queue_alloc would
generally have to traverse the whole list to find the entry
corresponding to an arrived event. Fix this by adding entries at the end
of the list.

Even if TearFree is active for the the CRTC we're synchronizing to. In
that case, for Present flips synchronized to vertical blank, the other
scanout buffer is immediately synchronized and flipped to during the
target vertical blank period. For Present flips not synchronized to
vertical blank, we simply use the MSC and timestamp values of the last
vertical blank period for timing purposes, and let the normal TearFree
mechanism handle display updates.
v2:
* Move manpage hunk to next change, since TearFree can still prevent
DRI2 page flipping with this change.

The xserver Present code can submit a flip in response to notifying it
that a vblank event arrived. This can happen before the completion event
of the previous flip is processed. In that case, we were clearing the
drmmode_crtc->flip_pending field prematurely.
Prevent this by only clearing drmmode_crtc->flip_pending when it matches
the framebuffer being scanned out since the flip whose completion event
we're processing.
