  avcodec/amfenc_h264: improve B-frame usability and simplify options
  
  - Query GPU caps for B-frame support and warn if unsupported.
  - Make `-max_b_frames` optional
  - Drop explicit `-pa_lookahead_buffer_depth` requirement in
  adaptive mode.

  avfilter/vf_libplacebo: implement rotation option
  
  Flipping can already be accomplished by setting the crop_w/h expressions to
  their negative values, so together these options can implement any of the
  common frame orientations.

  avcodec/mpeg12enc: Fix writing closed captions
  
  Broken in 6e225123d8583fdce55037b85eaef5453f201959, because
  ff_copy_bits() expects the amount of bits, not bytes to write.
  And because it relies on the buffer to be padded, using
  side_data->size * 8 is not possible. So partially revert
  said commit.
  
  Fixes ticket #11591.

  aarch64: increase default alignment for functions and constants
  
  Use 16-byte alignment (align=4) instead of 4-byte (align=2) in the function and
  const macros. This improves instruction fetch and NEON load performance on
  modern AArch64 CPUs.
