Perform more complex verification and validation. - signature.sh : extract and optionally compare Bench/Signature/Node count. - perft.sh : verify perft counts for a number of positions. - instrumented.sh : run a few commands or uci sequences through valgrind/sanitizer instrumented binaries. - reprosearch.sh : verify reproducibility of search. These script can be used from directly from the command line in the src directory. Update travis script to use these shell scripts. No functional change.
