This is an updated version of: [PATCH v4 1/1] avutils/hwcontext: When
deriving a hwdevice, search for existing device in both directions

There has been an objection that the earlier patchset would change API
behavior, and that this change should be limited to ffmpeg cli.

To achieve this, the API behavior is left unchanged now and a new function
av_hwdevice_ctx_get_or_create_derived() is added and used by the hwupload
and hwmap filters.

softworkz (3):
  avutils/hwcontext: add derive-device function which searches for
    existing devices in both directions
  lavu: bump minor version and add doc/APIchanges entry for
    av_hwdevice_ctx_get_or_create_derived()
  avfilter/hwmap,hwupload: use new av_hwdevice_ctx_get_or_create_derived
    method
