078c6f01f9 Make specific provisions for the kernel simulator used in the regression 
tests, other userland programs may need to include <geom/geom.h>.

as early as possible.

95c24b31df Make kernel dumps work with GEOM. 
Notice that if the device on which the dump is set is destroyed for
any reason, the dump setting is lost.  This in particular will
happen in the case of spoilage.  For instance if you set dump on
ad0s1b and open ad0 for writing, ad0s* will be spoilt and the dump
setting lost.  See geom(4) for more about spoiling.

b1876192f0 Eliminate some thread pointers which do not make sense anymore. 
Split private parts of geom.h into geom_int.h.  The latter should
never be included in class implemtations.

3773a65c0b Be more systematic about conversion of on-disk formats in a endian/width 
agnostic way.

Collapse the MBR and MBREXT methods into one file and make them endian/width
agnostic.

a5b2e75d32 Add a generic and general ioctl pass-through mechanism. 
It should now be posible to issue ioctls to SCSI CD drives.

dd84a43c1d First commit of the GEOM subsystem to make it easier for people to 
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.
