Babeltrace 1.1. Since then, babeltrace-log is broken when it needs to

Fix: handle new streams in get_data_packet()
- don't skip ask_new_streams() if new metadata _and_
new streams are available.
- goto retry after getting new streams.
- Add missing "ret = 0" assignment at the end of the function. Takes
care of "possible use of uninitialized variables" warnings in the
caller given by gcc.

Fix: accept empty metadata on append
"Append" should accept receiving metadata packets that contain exactly 0
byte of metadata payload. This kind of flush can happen on trace
teardown.
