Diego Biurrun 88bd7fdc82 Drop DCTELEM typedef
It does not help as an abstraction and adds dsputil dependencies.

Anton Khirnov f7d15d2f42 4xm: operate with pointers to AVFrames instead of whole structs.

Aneesh Dogra 9b55b4bb3a 4xm: Prevent buffer overreads.
4xm decoder while decoding i2 frames can overread the buffer if proper checks

Ronald S. Bultje 3fa646e859 Revert "4xm: Prevent buffer overreads."
This reverts commit 295a7c0238. The
patch breaks decoding of regular files (e.g. fate-4xm-2).

Aneesh Dogra 4b84f68223 4xm: pass the correct remaining buffer size to decode_i2_frame().
frame_size is the number of bytes left in the packet, so if we are passing
buf-4 we can safely read frame_size+4 bytes.
