Refactored ib_write in the same way as ib_read (described in #153). Merged separate completion queue polls to ib_write. Closes #167

Refactored the way ib_read() handles the refence counts for the samples it uses. This is based on the algorithm described in issue #153

Solved some state problems. This commit also solves #154, which was caused by a non-terminated thread. (This thread will be removed in a later commit anyway

Source and target successfully connect and node changes status from STATE_STARTED to STATE_CONNECTED in this commit. Next step will be to fix ib_stop and ib_disconnect to make the target able to accept new connections.

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

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

Basic implementation of zero-copying is done. The is still a problem with rread = hook_read_list. It doesn't return anything after the fourth read

ib_write() now takes data directly from the super pool instead of copying it. ib_read() still copies data and the code needs cleanup after zero-copy is implemented

Implemented disconnect function on source and target side. The cleanup function doesn't go through completely yet, probably because rdma_destroy_id blocks because not everything in the rdma_cm_id is destroyed yet.

This commit should be able to create a connection between two nodes.
This commit isn't checked for bugs and no memory management is done.
Furthermore, no poll threads are implemented.
