If init_get_bits fails the GetBitContext is invalid and must not be
used. Check the return value in dirac_header and propogate the error.

For example, the encoder may return MFX_WRN_INCOMPATIBLE_VIDEO_PARAM warning
i.e. ret==5 old loop implementation will repeat several times until output buffer
overflow. New implementation explicitly uses loop only for device busy case.

Avoid possible issues with memmapped hardware buffers in
case VDA is not doing a conversion on behalf of the user
and make the code more proper as working example.

Since the new PNS implementation has been merged and is no longer considered
proof of concept (as it's much more complex and better than the previous), change
the comments to reflect that. We need people testing it (since all AAC profiles
require it to be on by default) and having it tagged as proof of concept might drive some away.

When compiling libavutil/internal.h as C++11, clang warns that a space
is required between a string literal and an identifier. Put spaces
in concatenations of string literals and EXTERN_PREFIX.

Freeze picture release should be set to 1 when we're responding to a
fast update request. For simplicity we set it for all intra frames,
including those that starts a GOP.
Fixes issue where Tandberg MXP1700 does not recover from packet loss
state since it's waiting for the freeze picture relase indication.

Ref H.261 recommendation section 4.2.1.3, setting the still image flag
to 1 disables still image mode. Some decoders require this in order to
decode the bitstream as normal video.
Fixes H.261 calls to Cisco E20.
Also, reserved (aka spare) bits should be set to 1 unless specified
otherwise.
