Change the bounds_check_with_label API to also take a cpu_disklabel
reference for making transferral of meta-information possible from readdisklabel to bounds_check_with_label. The first (and maybe only) thing that will use this is the multi-disklabel-format code on the alpha where the labelsector is passed via cpu_disklabel so the label write-protection can work correctly no matter what label was found. Also use a new macro DKBAD to get at the dkbad field of the cpu_disklabel implementations that contain it. This too is for multi-disklabel architectures where the "bad" field can be inside a union. Use this macro as a means for a driver to check if an architecture supports dkbad constructs. Remove proto of bounds_check_with_label from all MD disklabel.h as it is in sys/disklabel.h. I have not been able to test the changes everywhere, if I break anything I apologize, and promise to fix it as soon as I become aware of it.
