Zdenek Kabelac a59c3731c3 Improve test suite
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.)
