sparse struct initializations before we extend the struct with
new OAM related member functions.

af63f9546a Now that the sectorsize and mediasize are properties of the provider,
don't take the detour over the I/O path to discover them using getattr(),
we can just pick them out directly.

Do note though, that for now they are only valid after the first open
of the underlying disk device due compatibility with the old disk_create()
API.  This will change in the future so they will always be valid.

bd4b849139 Add the new g_slice_config() call, which can add/delete/change a slice,
with support for trying, doing and forcing.

This will eventually replace g_slice_addslice() which gets changed from
grabbing topology to requing it in this commit as well.

d41562720e Add a proof-of-concept encryption class.
"The only hard problem in cryptography is key-management."

All sectors are encrypted with AES in CBC mode using a constant key,
currently compiled in and all zero.

To activate this module, write the magic header on the partition:

	echo "<<FreeBSD-GEOM-AES>>" | dd conv=sync of=/dev/md98

The encrypted device will be one sector shorter and have ".aes"
appended to its name.
