07107de9bc Introduce the concept of "magic spaces", and implement them in most of
the relevant classes.

Some methods may implement various "magic spaces", this is reserved
or magic areas on the disk, set a side for various and sundry purposes.
A good example is the BSD disklabel and boot code on i386 which occupies
a total of four magic spaces: boot1, the disklabel, the padding behind
the disklabel and boot2.  The reason we don't simply tell people to
write the appropriate stuff on the underlying device is that (some of)
the magic spaces might be real-time modifiable.  It is for instance
possible to change a disklabel while partitions are open, provided
the open partitions do not get trampled in the process.

of the device magic stuff might occupy.

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.

132f08d017 Teach GEOM about Sun disklabel formats.
The detection code in this method is written so that it should work on
all architectures which means that you can plug a Sun disk into a i386
now and access the partitions.

We still need an endian-agnostic ufs/ffs before this is really
interresting, but the main focus was to get sparc64 onto the GEOM
trail.
