add bitrate calculation to yami-utils

Add decoder and encoder latency log to yamidecode and yamitranscode(for performance test)

add latency information to yami-utils

yamitranscode will copy input to output if it can can't decide output format.

when yamitranscode cannot determine the output codec and the input is a yuv (I420 or NV12) it will apparently hang when in reality is just copying the input YUV to...

It introduces overhead, https://github.com/01org/libyami/blob/apache/encoder/vaapiencoder_h264.cpp#L2003. Send it when params changed will save cpu.

This will help us get pure encoder performance.

Fix function encoder capability mismatched with driver's table.

Instead of maintaining a local copy of capability. could we point to driver capability? thank you
