fate: make lavfi tests output only md5
Instead of saving huge raw files, use the md5: output pseudo-protocolto calculate the checksum of the file directly. This is especiallyuseful when testing on remote targets as it avoids transferring 3.6GBover the network.
Sort lavfi pixdesc tests.
Increase readability and robustness, as the test result is not goingto differ if the order of the pixfmts codes changes.

Fix lavfi pixdesc test
This test verifies the pixdesc code by comparing the output with andwithout a filter which should have no effect on the image. Since theavailable pixel formats depend on the byte order of the machine, asimple reference checksum is not possible....
