Start named as auth and recursive server in pairwise

Browse Source 
The script will start the named process configured as both an
authoritative and recursive server for each pairwise ./configure
configuration. The test is considered successful if the named process
runs until the 5-second timeout is triggered, and there is no named.lock
file present, indicating that named did not crash on shutdown.
