Evolve the ctlreq interface added to geom_gpt into a generic
partitioning class that supports multiple schemes. Current schemes supported are APM (Apple Partition Map) and GPT. Change all GEOM_APPLE anf GEOM_GPT options into GEOM_PART_APM and GEOM_PART_GPT (resp). The ctlreq interface supports verbs to create and destroy partitioning schemes on a disk; to add, delete and modify partitions; and to commit or undo changes made.
