Currently the only way to open a DRM device for libva is to scan the
list of DRM render nodes using udev. This works nicely for the general
case, but requires a few extra ioctls that are not currently added in
the video device process seccomp allowlist so we would like to get rid
of it.
One can also argue that how to detect the DRM device should be left to
the application, so this CL allows users to explicitly specify which DRM
device they want to open. As a helper, it also adds an iterator over
standard DRM render nodes locations to provide similar functionality
without requiring extra ioctls.

The raw capabilities should not depend on the value for rt_format.
Both in the Intel and Mesa implementations it can be seen that setting
VAConfigAttribRTFormat as a parameter to vaCreateConfig only serves as a
way to validate that the to-be-generated config supports it.
This means that the Intel implementation will only use it in
CheckAttribList, while Mesa will AND it with a precomputed bitmask of
supported values in vaCreateConfig.
Thus, creating one RawCaps instance per value of RT_FORMAT only serves
to create needless duplication.
Not only that, but it frequently makes the call to QUERY_CAPABILITIES
fail, as the resulting structures become too large to fit into the 1024
byte buffer.
Remove all traces of VA_RT_FORMAT_* from this code path. While we are at
it, note that the libva crate API for vaQuerySurfaceAttribute changed to
reflect that this call can return more than one attribute at once.
This is particularly important for VASurfaceAttribPixelFormat, as one
value per supported fourcc is returned. We now properly return one
instance of RawCaps per VA_FOURCC supported.
Also reflect that Surface attributes can be defined more than once
This is particularly the case with VASurfaceAttribPixelFormat, where the
driver will define one attrib per pixel format supported.
This can be seen in the Intel driver, for example, in
MediaLibvaCaps::QuerySurfaceAttributes.
The previous code assumed that a given attribute could only be defined
once, and thus used find(). It was refactored to use filter() instead.
The name of the method was changed to reflect that it can now return
more than one attribute per call. The return type was changed to Vec for
the same reason.

Fix the broken timestamp management in the virtio decoder device.
Timestamps are specified by the guest's user-space as a struct timeval,
which is effectively a (seconds, microseconds) pair. This pair is turned
into a u64 with nanoseconds units by V4L2, and passed to the virtio
device in that form.
This is fine so far, save for the fact that libvda works with 32-bit
timestamps. To accomodate that, we divided the original timestamp by
1_000_000_000, passed that truncated timestamp to the decoder backend as
a u32, and when the backend gives us decoded frames, multiplied their
timestamp by 1_000_000_000 again and passed that value as the frame
timestamp to the guest. For some reason, we also used the timestamp as
the key for the `NotifyEndOfBistreamBuffer` event, which forced us to
have a mapping table between an input buffer timestamp and its
corresponding resource ID. This in turn required that each input buffer
has a unique timestamp, lest they collide in the mapping table.
Anyway, the timestamp division by 1_000_000_000 means that any
sub-second timestamp information was lost during the decoding process.
This is not a problem with the Android V4L2 decoder which increases the
timestamp by one second for each frame and does not use sub-second
information, but clients that use *actual* timestamp information (like
ffmpeg) get pretty confused by that and abandon decoding with an error.
Fix this by passing the original 64-bit timestamp to decoder backends,
along with the 32-bit ID of the input resource. This allows backends to
directly send the NotifyEndOfBitstreamBuffer with the currect resource
ID, removing the need for the mapping table and unique timestamps for
input buffers.
More importantly, backends that can work with 64-bit timestamps (all of
them but libvda) can just pass the original timestamp to their decoder
logic and return it as-is in the PictureReady event. Libvda still
requires 32-bit timestamps, so we reproduce the truncation and mapping
table behavior inside the libvda backend (I also tried sending the
32-bit input resource ID as a timestamp to VDA, but it was not happy
with it). At least now that behavior is local to the VDA backend.
Thanks to this change clients other than the Android C2 decoder can get
proper timestamp information. One can argue that the code is also
simpler (except for libvda which adds a simple mapping table that we
were using before anyway).
