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

comedi: implement ADC and DAC directions, only DAC tested
...
The write / DAC direction has been tested with two output signals, see
etc/comedi.conf for reference. For now, the buffer size may not be
(considerably) smaller than 32kB, Comedi stops working for unknown
reasons. To compensate for the latency (always approx. one buffer size)
if only small sample rates are required, configure the path for
upsampling (sample-and-hold via rate parameter) at the same rate as
the out direction of the comedi node.
