update cppcheck command
don't implicitly downcast tagset_size()

Changes fileformat version for saved tagsets
lib/counting.{cc,hh},khmer/_khmermodule.cc: many downcasts removed
formatting only; astyle -A10 lib/counting.{cc,hh}
more downcast removal; scope reduction; prefix oper
labelhash downcast, no\!
this doesn't work, use git diff -w 96b2164f3e931f4bec20dc26ba7db6509c9db7f1 to review
