af509f9957 avcodec/proresenc_anatoliy: do not write into chroma reserved bitfields 
The layout for the frame flags is as follow:

   chroma_format  u(2)
   reserved       u(2)
   interlace_mode u(2)
   reserved       u(2)

chroma_format has 2 allowed values:
   0: reserved
   1: reserved
   2: 4:2:2
   3: 4:4:4

interlace_mode has 3 allowed values:
   0: progressive
   1: tff
   2: bff
   3: reserved

0x80 is what we expect for "422 not interlaced", and the extra 0x2 from
0x82 is actually writing into the reserved bits.

21f7a814ea avcodec/proresenc_anatoliy: do not write into alpha reserved bitfields 
This byte represents 4 reserved bits followed by 4 alpha_channel_type bits.

alpha_channel_type currently has 3 differents defined values: 0 (no
alpha), 1 (8b alpha), and 2 (16b alpha), all the other values are
reserved. The 4 initial reserved bits are expected to be 0.

6d35911667 avcodec/proresenc_kostya: do not write into alpha reserved bitfields 
This byte represents 4 reserved bits followed by 4 alpha_channel_type bits.

alpha_channel_type currently has 3 differents defined values: 0 (no
alpha), 1 (8b alpha), and 2 (16b alpha), all the other values are
reserved. This part is correctly written (alpha_bits>>3 does the correct
thing), but the 4 initial bits are reserved.

aa7ccd0ce9 avcodec/proresenc_kostya: use a compatible bitstream version 
Quoting SMPTE RDD 36:2015:
  A decoder shall abort if it encounters a bitstream with an unsupported
  bitstream_version value. If 0, the value of the chroma_format syntax
  element shall be 2 (4:2:2 sampling) and the value of the
  alpha_channel_type element shall be 0 (no encoded alpha); if 1, any
  permissible value may be used for those syntax elements.

So if we're not in 4:2:2 or if there is alpha, we are not allowed to use
version 0.
