[FFmpeg-devel] [PATCH 13/16] avutil/internal: Remove unused FF_SYMVER

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

It is unused since d63443b9684fa7b3e086634f7b44b203b6d9221e.
Furthermore, it was always in the wrong header:
libavutil/internal.h is auto-included almost everywhere, but
FF_SYMVER would only ever be used at a few places, so a proper
header of its own would be appropriate for it.
