  libavutil: Undeprecate the AVFrame reordered_opaque field
  
  This was marked as deprecated (but only in the doxygen, not with an
  actual deprecation attribute) in 81c623fae05 in 2011, but was
  undeprecated in ad1ee5fa7.

  arm: Emit .thumb_func directives
  
  Prior to Xcode 9.3, the clang built-in assembler didn't support
  altmacro, and gas-preprocessor was used for assembling for arm/darwin.
  
  For thumb functions, gas-preprocessor took care of adding the .thumb_func
  directives, but when now being able to assemble without gas-preprocessor,
  we need to add these directives ourselves.

• libx264 : Pass the reordered_opaque field through the encoder

  11 octobre 2018, par Martin Storsjö

  libx264: Pass the reordered_opaque field through the encoder
  
  libx264 does have a field for opaque data to pass along with frames
  through the encoder, but it is a pointer, while the libavcodec
  reordered_opaque field is an int64_t. Therefore, allocate an array
  within the libx264 wrapper, where reordered_opaque values in flight
  are stored, and pass a pointer to this array to libx264.
  
  Update the public libavcodec documentation for the AVCodecContext
  field to explain this usage, and add a codec capability that allows
  detecting whether an encoder handles this field.
