Evolve the ctlreq interface added to geom_gpt into a generic partitioning

(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.
Does this mean we can expect to see the disabling of GEOM exclusive-use
protections disappear from normal administrative activities soon, as there
will now be approved channels to incrementally change the layout of in-use
partition tables?
Yes, that's the idea. A tool will be developed first that uses these verbs
(though I already have a regression test suite capable of creating and
modifying APM and GPT partitions). After that the idea is to migrate other
partitioning schemes and slicers into this framework. The end-result being a
single tool for partitioning disks with any and all schemes supported by the
framework and using the ctlreq mechanism to work on live disks.
Sounds great!
