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.

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

Node can determine if data should be send inline
...
The user can set the maximum size of the inline data and the node checks
if a sample can be send inline. This commit doesn't contain a info
message to the user about what the final max inline size will be. (The
HCA will probably change the value set by the user.)

Added buffer to ib_write()
...
Now, ib_write() reads every cycle cnt values from the Completion Queue.
If it is not able to return them to the framework immediately, it
temporarily saves them on a stack.
ib_write() checks every cycle if the stack is non-empty and if it is
possible to return values from the stack to the framework.

Fixes #166 , all node interfaces are modified
...
The functions now look like this
int node_read(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);
int node_write(struct node *n, struct sample *smps[], unsigned cnt, unsigned *release);
This commit enables nodes to control how many samples will
be released by the framework through *release

Events are now monitored in a separate thread. The segmentation faults we saw earlier were caused because we exited ib_start before we created a protection domain, which is used by memory_allocation
