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).
