b51ea35631 Use the M_CCD malloc bucket instead of M_DEVBUF. 
Don't keep a private freelist of a low number of trivially small structures.

four-clause BSD license in the file, one will do.

ddbf51af0c Find places to store the previously implicityly passed unit number in 
the three configuration ioctls which need a unit number.

Add a "ccd.ctl" device for config operations.

Implement ioctls on ccd.ctl which rely on the explicityly passed
unit numbers.

Update ccdconfig to use the new ccd.ctl interface.

Add code to the kernel to detect old ccdconfig binaries, and whine
about it.

Add code to ccdconfig to detect old kernels, and whine about it.

These two compatibility measures will be retained only for a limited
period since they are in the way of GEOM'ification of ccd.

d2128d818f Add a very simple but functional GEOM mirror class. 
This is committed more as an instructive tool than as a production
facility, but this will change over time.

d320fdbca7 Now that we have non-geom_disk based drivers, we need to cover for those, 
in case they return EOPNOTSUPP on an ioctl.

4b2f4ce94e Always issue ioctls as BIO_GEATTR requests. The direction of data copies on 
ioctls are no reliable indication of the ioctls "set" or "get" nature or if
such simplistic categories can even be applied.

51a5c572a6 BSD disklabels expose the controling label though the 'c' partition, and 
some trick is necessary to prevent further BSD geoms from attaching to
that.  Our old trick was to make sure we don't attach to a geom from
the "BSD" class, but this doesn't work if an intermediary geom obscures
this fact.  Instead, calculate the MD5 checksum of the label we target
and ask if anybody below us loves that label.  If they do we don't.

1e90b74683 Solve another bug in the mapping code: correctly skip lock sectors. 
Make sure sector zero is protected if it contains metadata.

Lower WARNS for gbde to 3 on non-i386 archs.  rijndael-fst is evil
but appearntly does the right thing and passes the test-vectors.

8ba4488cea Add support for the PC98 platform to the ATA driver. 
This mostly consists of functionality to serialize accesses to
the two ATA channels (which can also be used to "fix" certain
PCI based controllers).
Add support for Acard controllers.
Enable the ATA driver in PC98 GENERIC, and add device hints.
Update man page with latest support.

The PC98 core team has kindly provided me with a PC98
machine that made this all possible, thanks to all that
contributed to that effort, without that this would
probably newer have been possible..

19c61e97fb Conceiveably, there may exist an algorithm which can tell if a sequence of bytes 
are the output of AES/128/CBC or ARC4RANDOM.  Encrypt the random data with which
we wipe when we get a BIO_DELETE to make such an algorithm useful.
