Symbiotic 3: New Slicer and Error-Witness Generation(Competition Contribution)

Symbiotic 3 is a new generation of a bug-detection tool for C programs. The tool sticks to the combination of program instrumentation, slicing, and symbolic execution. Large parts of the tool are rewritten, in particular the managing and instrumentation scripts and slicer (including points-to analysis). Further, the symbolic executor Klee has been modified to produce error-witnesses. The changes are commented in the description of the tool workflow.
