940b8b5861 h264: avoid pointless copying of ref lists 
ref_list is constructed from other fields per slice when needed, so do
not copy it for both frame and slice threading.
default_ref_list is constructed per frame and still needs to be copied
to per-slice contexts for slice threading, but a copy is not needed for
frame threading.

f07ef2d9c9 lavr: call mix_function_init() in ff_audio_mix_set_matrix() 
This is needed if a custom matrix is set by the user after opening the
AVAudioResampleContext because the matrix channel count can change if
different mixing coefficients are used.

The mask `x && (1 << y)' is incorrect and always yields true.

The correct form should be `x & (1 << y)'.

e33db35b4a theora: Skip zero-sized headers 
This fixes a regression since d9cf5f51 with theora over RTP
(possibly with other variants of theora as well).

In theora over RTP, the second of the 3 headers turns out to be
0 bytes long, which prior to d9cf5f51 worked just fine. After
d9cf5f51, reading from the bitstream reader fails (since the reader
wasn't initialized but returned an error if initialized with 0 bits).
