Change vp9_get_encoder_config.

Add vp9_dump_encoder_config for config comparison.

This function will generate the same VP9EncoderConfig used by the
vpxenc command given below.
The configs in the vpxenc command corresponds to parameters of
vp9_get_encoder_config() as follows.

WIDTH:   frame_width
HEIGHT:  frame_height
FPS:     frame_rate
BITRATE: target_bitrate

INPUT, OUTPUT, LIMIT will not affect VP9EncoderConfig

vpxenc command:
INPUT=bus_cif.y4m
OUTPUT=output.webm
WIDTH=352
HEIGHT=288
BITRATE=600
FPS=30/1
LIMIT=150
./vpxenc --limit=$LIMIT --width=$WIDTH --height=$HEIGHT --fps=$FPS
