Data in EbmlBin objects is never changed after being read from the
input file (save for two specific cases with encoded CodePrivate), so
using AVBufferRef we can prevent unnecessary copy of data by instead
creating new references to said constant data.

This seems to confuse Github users into thinking that we may accept pull
requests. We do not accept pull requests.

Sending patches to the ffmpeg-devel mailing list is our preferred method

The pseudo palette allocation is optional now. But if it's still
allocated (like the internal get_buffer2 implementation does, for
compatibility), it shouldn't print a warning.

This is shared test and this simplifies code a bit. Follow up
commit will have additional tests for this function.
