and examples/resize_util.c. These functions were added in:
3cd37dfeb Adds a non-normative resize library to vp9 encoder
but never used meaningfully in the library.
This mirrors the change in libaom:
d10029bb4b Restore function prototype of av1_resize_frame420
except that vp9_resize_frame420() was never exported in the shared
library, so can be deleted along with the rest.
The reasoning for removing examples/resize_util.c is the same: it is not
useful and examples should use the public functions of the libvpx
library.
