* qatar/master: (22 commits)
  arm: remove disabled function dct_unquantize_h263_inter_iwmmxt()
  Remove commented-out call to non-existing function print_pow1().
  Do not decode RV30 files if the extradata is too small
  flashsv: split flashsv_decode_block() off from flashsv_decode_frame().
  ppc: remove disabled code
  libspeexdec: Drop const qualifier to silence compiler warning.
  libopenjpeg: Drop const qualifier to silence compiler warning.
  alac: Remove unused dummy code.
  Remove unused structs and tables.
  vaapi: do not assert on value read from input bitstream
  flashsvenc: replace bitstream description by a link to the specification
  flashsvenc: drop unnecessary cast
  flashsvenc: improve some variable names and fix corresponding comments
  flashsvenc: merge two consecutive if-conditions
  flashsvenc: merge variable declarations and initializations
  flashsvenc: convert some debug av_log() to av_dlog()
  flashsvenc: whitespace cosmetics
  flashsvenc: drop some unnecessary parentheses
  flashsvenc: fix some comment typos
  aacps: skip some memcpy() if src and dst would be equal
