[PATCH v6 2/3] dm: export a table+mapped device to the ioctl interface

From: Will Drewry One function is added which allows for a programmatically created mapped device to be inserted into the dm-ioctl hash table. This binds the device to a name and, optional, uuid which is needed by udev and allows for userspace management of the mapped device.
