Dont call READCAPACITY from every single test.
Remove two arguments from the test signatures and turn them into globals.
remove the ret++ silliness. Tests return 0 : all ok, -2, skipped or -1 : test failed
Harmonize the signatures for READ10/WRITE10 to match the ones for READ12/16 and WRITE12/16
This breaks the API/ABI so this forces the next version of the library to bump the major version to 2.0
