The test script now resolves the device node into a <label,minor> pair, so that the blocktest driver itself no longer has to. This removes blocktest's dependency on VFS' internal data structures. Also allow blocktest to be linked using with gcc/clang.
Instructions on how to use blocktest: 1) compile it by running 'make' 2) read test.sh 3) edit and uncomment one line from test.sh 4) run './test.sh' 5) read the output in /var/log/messages
