This commit bumps the libmpv version to 1.102
drm-osd-plane -> drm-draw-plane
drm-video-plane -> drm-drmprime-video-plane
drm-osd-size -> drm-draw-surface-size
"draw plane", as in the plane that OpenGL draws to, whether it be
video + OSD or just OSD.
"drmprime video plane", as in the plane used for hwdec video imported
via drmprime.
"draw surface size", as in the size of the surface used for the draw plane
The new names are invariant whether or not hwdec_drmprime_drm is being
used or not. The original naming was very confusing, as when doing
regular rendering (swdec or vaapi) the video would be displayed on the
"OSD plane", and the "Video plane" would remain unused.

Add general primary/overlay plane option to drm-osd-plane-id and
drm-video-plane-id, so that the user can just request any usable
primary or overlay plane for either of these two options. This should
be somewhat more user-friendly (especially as neither of these two
options currently have a useful help function), as usually you would
only be interested in the type of the plane, and not exactly which
plane gets picked.

This is to improve the experience when running with default settings
on a driver that doesn't have any overlay planes (or indeed only one
plane), but still supports DRM atomic. Since the drmprime video plane
is set to pick an overlay plane by default it would fail on these
drivers due to not being able to create any atomic context. Users with
such cards had to specify --drm-video-plane-id manually to some bogus
value (it's not used after all).
The "video" plane is only ever used by the drmprime-drm hwdec interop,
which is not used at all in the typical usecase where everything is
actually rendered on to the "OSD" plane using EGL, so having an atomic
context without the "video" plane should be fine most of the time.

The previous code did not save enough information about the old state,
and could end up changing what plane the fbcon:s FB got attached to,
or in worse case causing a blank screen (observed in some multi-screen
setups on Sandy Bridge).
In addition refactor the handling of drmModeModeInfo property blobs to
not leak, as well as enable reuse of already created blobs.

First fix a memory leak when skipping cursor planes by inverting the
check and putting everything, but the free, in the body.
Then fix a missed drmModeFreePlane by simply copying the fields of the
drmModePlane we are interested in and freeing the drmModePlane struct
early.

We are currently using primary / overlay planes drm objects, assuming that primary plane is osd and overlay plane is video.
This commit is doing two things :
- replace the primary / overlay planes members with osd and video planes member without the assumption
- Add two more options to determine which one of the primary / overlay is associated to osd / video.
- It will default osd to overlay and video to primary if unspecified

This patch adds
- DRM connector object to atomic context.
- fd property to the drm atomic object as well as a method to read blob type properties.
This allows to ensure that the proper connector is picked up, especially when specifying it
from the commandline, and also allows to make sure we're using the right one when embedding
with interop into an application.

Passing in an invalid DRM overlay id with the --drm-overlay option would
cause drmplane to be freed twice: once in the for-loop and once at the
error-handler label fail.
Solve by setting drmpanel to NULL after freeing it.
Also the 'return false' statement after the error handler label should
probably be 'return NULL', given that the return type of
drm_atomic_create_context returns a pointer.

This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.
That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.
This has been tested on RockChip ROCK64 device.
