...
Both RC and UC are connected. So the check I changed should check for
NOT UDP (UD), instead of TCP (RC)

...
Before, it waited until it is really connected. That caused problems,
because the send side will start immediately sending if it is connected.
Especially at high rates (>100k) this was a problem.

As discussed in issue #186 and on IM. This function check every 2048th

Performance improvement for UDP

after it got ah_attr.

ib_read() measures the time with time_now() (from villas/timing.h) and
sets all flags at receive side.

Replace sleep by a better check
...
Prior to this commit, we called rdma_disconnect() and waited for a fixed
amount of time. This check was kind of arbitrary. Now, we keep polling
the receive Completion Queue until ib->conn.available_recv_wrs is zero
and all receive samples are thus given back to the framework.

RDMA CM ID is set to TCP, the QP has to be set to a RC. If it is set to
UDP, it has to be set to UD.
