enc->streams->end_granule used uninitialized in encode_buffer() if the
stream contains no audio (opusenc_example /dev/null out.opus).

enc->frame_size_request used uninitialized in encode_buffer() if the
frame size was not explicitly set.

enc->callbacks used uninitialized if the encoder is created with
ope_encoder_create_callbacks() and callbacks is NULL.

If the stream is drained without writing any audio and the frame size is
smaller than the encoder latency, the assertion (enc->streams == NULL)
would fail because pad_samples was computed using an incorrect value of
enc->global_granule_offset before it was set in init_stream(), causing
the padding to be insufficient to drain the stream.

These are only used by doxygen to speed up regeneration of existing
output after source changes, which isn't something that's going to
happen on a snapshot of installed documentation.

And yes, I've really had enough swap files in a single dir to need this.

Thanks to Dmitry for reporting the bug.
