19128408ac avcodec/mpegpicture: fix "stride changed" failures in gray mode 
Before adding uvlinesize check, I was seeing failures decoding
some video with ffmpeg compiled with --enable-gray and using AV_CODEC_FLAG_GRAY.

[mpeg2video @ 0x7fa193818c00] get_buffer() failed (stride changed: linesize=1280/1280 uvlinesize=0/640)

89f9332fdf avcodec: set correct return value in ff_mpeg_ref_picture 
In function ff_mpeg_ref_picture(), it returns 0 on the error path that
the return value of av_buffer_ref() is NULL. 0 indicates success, which
seems to deviate from the fact. Set ret to AVERROR(ENOMEM) to propagate
the error status to the callers.

bb4c9d0a8e avcodec: Don't assume separate u and v planes in ff_alloc_picture 
alloc_frame_buffer in ff_alloc_picture asserts that the linesize
of planes 1 and 2 are the same. If the pixfmt has a single uv
plane, like NV12, this won't be true.

So, let's only do this check if there are more than 2 planes.

We never hit this with previous hw formats because they don't set
linesize to meaningful values, but the cuda hw format sets the
values based on the underlying data layout.

1aa24df74c lavu: Deprecate AVFrame.error[] 
These field are difficult to interpret, and are provided by a single
encoder (mpegvideoenc). In general they do not belong to a structure
containing raw data only, so remove them from AVFrame.

Mpegvideoenc now uses a private field in Picture for its internal
computations.
