PROTON-2375: Small connection_driver API change
Make connection_driver API more efficient when finishing writes
This allows epoll proactor to efficiently avoid delving directly into
the transport buffers.
Also small small clean ups.

> Key: PROTON-2375
> URL: https://issues.apache.org/jira/browse/PROTON-2375
> Project: Qpid Proton
> Issue Type: Improvement
> Components: cpp-binding, proton-c
> Affects Versions: proton-c-0.34.0
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
>
> This is a small ABI preserving change to the connection_driver API which
> makes the process of informing the connection_driver that writes have been
> completed and the buffer can be returned more efficient.
> {{pn_connection_driver_write_done()}} is changed to return any new bytes that
> may have been generated up to this point so that the proactor (or other event
> loop) doesn't have to immediately query for them.
> Note this is ABI preserving because previously there was no return value so
> code couldn't be using it. If old code ignores the return value then this is
> no change in behaviour.
