avcodec/codec_internal: Include avcodec.h for enum AVCodecConfig

Forward-declaring an enum is not legal C (the underlying type of
the enum may depend upon the enum constants, so this may cause
ABI issues with -fshort-enums); compilers warn about this
with -pedantic.

This essentially reverts 7e84865cff2d174beede69a2018c0d81c8cc3b02.
Notice that almost* all files that include codec_internal.h also
need to include avcodec.h, so this does not lead to unnecessary
rebuilds.

This addresses part of #22684.

*: The only file I am aware of that defines an FFCodec and does not
need AVCodecContext as complete type is null.c (but even it already
includes it implicitly); the avcodec.c test tool seems to be the only
file where this commit actually leads to an unnecessary avcodec.h
inclusion.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
