The code blindly trusted buffer offsets read from the file in the RLE
decoder. Explicitly check the offset. Also error out on other RLE
decoding errors.

The r10k and avrp decoders would previously store 12 bit precision
for the blue channel, which is inconsistent and probably not a
desirable behaviour.
Now the 2 unused extra bits are set to 0.
This is possibly not ideal either as RGBA1010102 format has the same
layout but stores alpha in these bits, thus explicitly setting them
to 1 might be preferable.

Since the VDPAU pixel format does not distinguish between different
VDPAU video surface chroma types, we need another way to pass this
data to the application.
Originally VDPAU in libavcodec only supported decoding to 8-bits YUV
with 4:2:0 chroma sampling. Correspondingly, applications assumed that
libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output.
However some of the new HEVC profiles proposed for addition to VDPAU
would require different depth and/or sampling:

...as would lossless AVC profiles:

To preserve backward binary compatibility with existing applications,
a new av_vdpau_bind_context() flag is introduced in a further change.

This can be used by the application to signal its ability to cope with
video surface of types other than 8-bits YUV 4:2:0.

This carries the pixel format that would be used if it were not for
hardware acceleration. This is equal to AVCodecContext.pix_fmt if
hardware acceleration is not in use.

This is to avoid proliferation of similar tables in following changes.
