Add make help target. Add LVM_TEST_PARALLEL to support parallel runs of tests Work around the problem the dmsetup table/info may return error by using dmtable and dminfo function that will use 'should'. (Error happens when some concurently running process removes table entry while dmsetup command resolves table entries inside the loop.)
