Implemented ib_reverse()
...
The only value that gets reversed is src- and dst address. Fixes #175 .

Added fallback which sets mode to listening mode
...
Before, the node would throw an error as soon as it cannot connect to
the remote host. Now, it will throw a warning and switch to listening
mode (in which it will wait for another node to connect).

Solved problem with blocking thread
...
In the case that a node was already disconnected but not stopped,
rdma_cm_get_event always blocked and we coulnd't join the threads. This
is solved in this commit by registering SIGUSR1 to the CM event thread.
This bug originated in issue #152

Added extra check for inline mode. Closes #164
...
The actual maximum size for inline mode is now returned to the user and
there is a check that inline_mode is either 0 or 1. Furthermore, this
commit includes a minor improvement in ib_write()

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.

ib_write and ib_read handle memory in a way that the pool doesn't underrun now. Sending data inline is broken in this commit

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

Removed bugs with regard to the zero-copy implementation. This commit is able to send -r 5000 -l 50000 with villas pipe. With a higher -r, the source throws errors that there aren't any receive WRs, so probably pipe doesn't fill up the WRs fast enough
