runtime: fixed case where tagged stream blocks produce zero length tags
blocks: allow extra header chunks in wav_file_source
qa_fir_filter_with_buffer.cc : Fix incorrect use of sizeof().

Addresses CID 1046078. sizeof the product of two numbers is wrong.
The intent is to set the actual_output vector to zero. This appears
to break QA, the test numbers need updating.

dc_blocker_cc_impl.cc, dc_blocker_ff_impl.cc : Fix uninitialized pointer.

Addresses CID 1043254, 1043255.

As long as the code properly follows the d_long_form state, existing code
is fine. However by forcing the unused pointers to NULL, we should catch
mistakes as core dumps, not mysterious failures.
