libavutil/stereo3d: fix prefix matching in *_from_name() functions
The three *_from_name() functions used av_strstart() for prefix matching,
which returns incorrect results when one name is a prefix of another.
av_stereo3d_from_name("side by side (quincunx subsampling)") matched
"side by side" at index 1 and returned AV_STEREO3D_SIDEBYSIDE instead of
AV_STEREO3D_SIDEBYSIDE_QUINCUNX. Similarly,
av_stereo3d_primary_eye_from_name("nonexistent") matched "none" and
returned AV_PRIMARY_EYE_NONE instead of -1.
Switch all three functions from av_strstart() to strcmp() for exact
matching. No in-tree callers rely on prefix matching.
