• avcodec/hqx : Don't zero in small chunks, don't zero twice

  avcodec/hqx: Don't zero in small chunks, don't zero twice
  
  Up until now, decode_block() zeroed every block (of 128 bytes)
  before decoding a block; yet this is suboptimal for all modes,
  because all modes need to reset all the blocks they use anyway
  and so it should be done in one go for all blocks.
  
  For the alpha modes (where blocks need not be coded) all blocks
  are zeroed initially anyway, because decode_block() might not
  be doing it, so zeroing there again for the coded blocks is
  a waste.

• avcodec/hqxvlc : Make dc9, dc10 VLC tables static

  13 mars, par Andreas Rheinhardt

  avcodec/hqxvlc: Make dc9, dc10 VLC tables static
  
  It allows to share them between frame threads.
  dc11 can unfortunately not be made static without increasing
  LOCALBUF_ELEMS in vlc.c.
