BUG/MINOR: stream_sock: don't remove BF_EXPECT_MORE and BF_SEND_DONTWAIT on partial writes
The flags are one-shot but should be maintained over all send() operations
as long as send_max is not flushed. The flags were incidentely cleared once
a complete send() was performed, regardless of the fact that the send()
might have been on the first half of a buffer before a wrapping. The result
is that on wrapping data (eg: which happens often with chunked encoding),
many incomplete segments are transmitted instead of being aggregated.
The fix consists in only flushing the flags only once send_max is empty,
which was the expected behaviour.
This fix should be backported to 1.4 though it is not critical, just sub-optimal.
