Mp4: fixed reading 64-bit atoms.

Previously there was no validation for the size of a 64-bit atom
in an mp4 file.  This could lead to a CPU hog when the size is 0,
or various other problems due to integer underflow when calculating
atom data size, including segmentation fault or worker process
memory disclosure.
