Dave Wallace d85075e6e4 make test: VCL extended test cases 
- Add VCL cut thru uni-direction test over multiple sockets
- Add VCL cut thru bi-direction test over multiple sockets
- Add LDP cut thru uni-directional test over multiple sockets
- Add LDP cut thru bi-directional test over multiple sockets
- Add VCL thru host stack uni-direction test over multiple sockets
- Add VCL thru host stack bi-direction test over multiple sockets
- Add LDP thru host stack uni-directional test over multiple sockets
- Add LDP thru host stack bi-directional test over multiple sockets
- Fix validateResults to ensure worker_server process is killed if
  it still exists after running the test.
