3a3fcd72dd Make this a true GEOM class:
Attach to the component devices using GEOM semantics.
        Create a GEOM provider instead of using disk_create()
        Use the GEOM OAM api for configuration.

I saw approx ~1% speedup in througput and ~7% in latency in a
simple minded test of a two-disk striped device.

This file was repo-copied from src/sys/dev/ccd/ccd.c.

This is not yet linked into the build.

0f557e0ac0 Further devilification of CCD:
Change the list interface to simplify things.
Remove old list ioctls which bogusly exported the softc to userland.
Move the softc and associated structures from the public header to
the source file.

189337d81f Begin deevilification of CCD:
Make CCD a GEOM class.

For now only use this for implementing a OAM config method which
can return a list of configured CCD devices in the format which
"ccdconfig -g[v]" would normally output.

83d771de78 Simplify the GEOM OAM api: Drop the request type, and let everything
hinge on the "verb" parameter which the class gets to interpret as
it sees fit.

Move the entire request into the kernel and move changed parameters
back when done.

6c87f8d5ea Introduce a init and fini member functions on a class.

4da6e74ce4 When a GEOM (/dev-)device is closed and we find that I/O requests are
still outstanding, give them a chance to complete.

If after 10 seconds we still find outstanding I/O requests, complete
the close with a console warning that the system is likely to panic
later on.

This is a workaround for umount -f not quite doing the right thing.

56dde750d5 Make bsd_disklabel_le_enc calculate the checksum and fill it in.
(If there is a legitimate need to correctly encode and pack a
disklabel with an invalid checksum custom tools can be built for
that.)

Make bsd_disklabel_le_dec() validate the magics, number of partitions
(against a new parameter) and the checksum.

Vastly simplify the logic of the GEOM::BSD class implementation:

Let g_bsd_modify() always take a byte-stream label.

This simplifies all users, except the ioctl's which now have to
convert to a byte-stream first.  Their loss.

g_bsd_modify() is called with topology held now, and it returns
with it held.

Always update the md5sum in g_bsd_modify(), otherwise the check
is no use after the first modification of the label.  Make the
MD5 over the bytestream version of the label.

Move the rawoffset hack to g_bsd_modify() and remove all the
inram/ondisk conversions.

Don't configure hotspots in g_bsd_modify(), do it in taste instead,
we do not support moving the label to a different location on the
fly anyway.

This passes all current regression tests.
