Merge remote-tracking branch 'qatar/master'
* qatar/master: wmalosslessdec: increase channel_coeffs/residues size wmalosslessdec: increase WMALL_BLOCK_MAX_BITS to 14. lagarith: check count before writing zeros. wmaprodec: check num_vec_coeffs for validity avidec: use actually read size instead of requested size avidec: return 0, not packet size from read_packet().
