Added a few corrections for sample size
...
* Meta data was not included in the calculation which determines if
sample should be send inline. This caused errors
* Meta data was not substracted from sample->length on receive side

Added meta data in transfer
...
ib_write() and ib_read() now point to the sequence, ts_origin, and format
members of struct sample in a separate scatter/gather element each.
ib_read() measures the time with time_now() (from villas/timing.h) and
sets all flags at receive side.

Merge branch 'ib-rearrange-qp' into develop
...
Closes #152 . As described in #182 , we will not rearrange the Queue Pairs
for connected mode. As soon as we test many-to-one connections for the
unrealiable connection, we will look again at this issue.

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.

Removed option to manually add QP type
...
The QP type is dependend on the port space of the RDMA CM ID. If the
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.

ib_read() now works for UDP
...
Node is now able to send data in RDMA_PS_UDP mode. Right now it creates
a new rdma_cm_id for every connection request. We could/should do this
differently
