video frame crc generator patch

video frame crc generator patch aligned to master branch

This plugin computes 32 bit CRC of luma and chroma for every video frame.
The CRC values are posted to appication as message.
It uses standard CRC algorithm to compute CRC values for every video frame.
The default polynomial, CRC mask, used for CRC generation is 0X04c11db7U
Different 32 bit CRC mask can be set through a crc-mask property.
It accepts selected YUV planar formats NV12, I420 and YV12.
Its a separate plugin which can be used in a video playing pipeline.
It can be used to carry out SW or HW decoder validation like H.264 or HEVC
It can be also used to carry out Allegro test suite verification.
