[Libguestfs] [PATCH VERSION 3] Generic partition creation interface.



This adds a "part-disk" command which can be used to quickly partition
a whole disk into a single partition.  Updates the tests and a recipe
to use it.

Rich.

Subject: [PATCH] Generic partition creation interface.

The current sfdisk interface works, but is somewhat limited
since it can only deal with MBR-style partitions.  For disks
larger than 2TB, MBR partitions are unsuitable and we need
to provide access to other partition table types (eg. GPT).

This commit introduces a generic partition creation interface
which should be future-proof and extensible.

The implementation is based on parted.
