A new drm client cap is required to enable user-space to advertise
if it supports modes with aspect-ratio. Based on this cap value, the
kernel will take a call on exposing the aspect ratio information in
modes or not.
This patch adds the client cap for aspect-ratio.

What's missing from the commit message is why this needs to be a flag that
userspace needs to enable,
instead of something that only counts as an informative query.
I gathered from danvet that blindly exposing things breaks existing userspace,
so could that information be added to the commit?
Agreed. This information indeed brings out the real reason for the patch.
Will add the details in the commit message in the next patch-set.
Also missing IGT tests, would be nice we at least get some verification things
work as expected.
Currently this is being tested with the corresponding userspace changes
in weston compositor, but a simple IGT on the same lines of kms_3d
can be prepared.
A separate test to check that the different aspect ratio modes are
correctly enumerated, and filtered out when the cap is not set seems
like a good idea.
As for actaully testing different aspect ratio modes, maybe just
intergrate that into testdisplay?
Alright. Will modify the testdisplay to have a
"test_aspect_ratio_modes", which will just set the aspect ratio modes
from the
connector modelist, to verify the basic functionality.
kms_aspect_ratio to do detailed testing will be taken later.
