gr-zeromq: Big rework for performance and correctness
- Use class hierarchy trying to maximize code re-use.
- Dont' drop samples on receive if the output buffer doesn't have
enough space.
- Don't drop tags on receive by putting tags in the future.
- Better metadata creation/parsing avoiding copying lots data.
- Always do as much work as possible in a single call to work()
to avoid scheduler overhead as long as possible.
- Allow setting the high watermark to avoid older version of
zeromq's default of buffering infinite messages and causing a
paging thrash to/from disk when the flow graph can't keep up.
