Fail decoding if strict compliance is requested.

The specification does not allow multiple bits to be set,
but some encoders do it anyway.
Applying it only to the first seems to give better results.

Avoid overwriting the bitstream buffer data before we
have ended processing the frame.
This is necessary to fix hwaccels which might try to use
the buffer during the end_frame call.
I am not sure but it is possible this could even trigger
a use-after-free if the av_fast_malloc allocated a new buffer.
This would require that decode_slice did not wind the bitstream
forward all the way to the end, which does not currently happen in
normal streams.

The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data.
(e.g., for 1080p white frame compared to a black frame can give sum of 255*255*1080*1920 > 2^32).

Previously this did a double free (and returned an error).

Prior to this on msvc/icl there was no handling of deprecated functions
and the deprecated warning was disabled.

After enabling there are a number of warnings relating to the CRT and
the use of the non-secure versions of several functions.  Defining
_CRT_SECURE_NO_WARNINGS silences these warnings.
