636631d9db Remove unnecessary libavutil/(avutil|common|internal).h inclusions
Some of these were made possible by moving several common macros to
libavutil/macros.h.

While just at it, also improve the other headers a bit.

005d058f42 lavfi/loudnorm: add an internal libebur128 library
Also contains the following changes to the library:
- add ff_ prefix to functions
- remove cplusplus defines.
- add FF_ prefix to contants and some structs
- remove true peak calculation feature, since it uses its own resampler, and
  af_loudnorm does not need it.
- remove version info and some fprintf(stderr) functions
- convert to use av_malloc
- always use histogram mode for LRA calculation, otherwise LRA data is slowly
  consuming memory making af_loudnorm unfit for 24/7 operation. It also uses a
  BSD style linked list implementation which is probably not available on all
  platforms. So let's just remove the classic mode which not uses histogram.
- add ff_thread_once for calculating static histogram tables
- convert some functions to void which cannot fail
- remove intrinsics and some unused headers
- add support for planar audio
- remove channel / sample rate changer function, in ffmpeg usually we simply
  alloc a new context
- convert some static variables to defines
- declare static histogram variables as aligned
- convert some initalizations to mallocz
- add window size parameter to init function and remove window size setter
  function
- convert return codes to AVERROR
- fix indentation
