Some decoding APIs support delayed output or a command for decoding
a frame doesn't need to be sequential to corresponding command for
getting decoded frame. For instance, subclass might be able to
request decoding for multiple frames and then get for one (oldest)
decoded frame or so.
If aforementioned case is supported by specific decoding API,
delayed output might show better throughput performance.

* Don't warn for live object, since ID3D11Debug itself seems to be
holding refcount of ID3D11Device at the moment we called
ID3D11Debug::ReportLiveDeviceObjects(). It would report live object
always
* Device might not be able to support some formats (e.g., P010)
especially in case of WARP device. We don't need to warn about that.
* gst_d3d11_device_new() can be used for device enumeration. Don't warn
even if we cannot create D3D11 device with given adapter index therefore.
* Don't warn for HLSL compiler warning. It's just noise and
should not be critical thing at all

As advised by !1366#note_629558 , the nice transport should be
accessed through:
> transceiver->sender/receiver->transport/rtcp_transport->icetransport
All the objects on the path can be accessed through properties
except sender/receiver->transport. This patch addresses that.

Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.

Spec says:
In a frame picture top_field_first being set to ‘1’ indicates that the
top field of the reconstructed frame is the first field output by the
decoding process. top_field_first being set to ‘0’ indicates that the
bottom field of the reconstructed frame is the first field output by
decoding process.
Here, the "output" should be interpreted just as the output order, not
including the decoding order. The field should be decoded as the order
they comes in the stream. Namely, no matter top_field_first is 0 or 1,
the first coming field is the first one to be decoded.

Instead of implementing exactly the same thing ourself but making
`GstBus` not know that it is the case.
Since we are *sure* that the bus can't have been access at the point
where we add the watch we are guaranteed that the current thread
maincontext is going to be used.

Context creation and retrieval is required, the symbols are exported
with the header missing. Users most likely define GST_USE_UNSTABLE_API
so they're aware of the implications of using a header that might change
between releases.

In practice, we encounter streams that have one or more temporal units
error. When that kind of error temporal units is in annex b format, the
whole temporal unit should be discarded.
But the temporal units before it are correct and can be used. More
important, because of the error temporal unit, the parser is in a wrong
state and all later temporal unit are also parsed uncorrectly.
We need to add this API to reset the annex_b state only when we meet
some temporal unit error.

1. store more tile info when parse tile group.
The column, row, tile offset and tile data size are all useful for
decoder process, especially for HW kind decoder such as VAAPI dec.
Also fix the tile group skip size for each tile data.
2. No min_inner_tile_width requirement in newest spec.
3. Calculate the sbs of each tile for both uniform tile and non-uniformi
tile.

The metadata OBUs, for example, ITUT_T35 has an undefined payload such
as itu_t_t35_payload_bytes field in AV1 spec, which may cause the failure
of parsing the trailings bits. We can give a warning and ignore this kind
of errors.
