Fix build w/o core library
Merge branch 'master' of https://github.com/BlueBrain/DisplayCluster
Implement interleaved compressed/send for pixel streaming.

Results in a 10% improvement in performance for the local test. The
image segmenter now calls a function for each generated segment. The
stream lib uses this to send out the segment directly, while the tests
still collect the segments to test their content.
