./run-all.sh can now take an optional argument to select whether to run
all test cases as before (default), to run these under valgrind
("valgrind"), to run P2P test cases with concurrent station interface
("concurrent"), or the concurrent P2P test cases under valgrind
("concurrent-valgrind").
valgrind cases report errors if a test case fails or valgrind reports an
error.
