3483cf5337 Don't force class to give a valid softc to g_slice_new(), it is not always 
needed.

124977fbb6 Remove the absolute count g_access_abs() function since experience has 
shown that it is not useful.

Rename the relative count g_access_rel() function to g_access(), only
the name has changed.

Change all g_access_rel() calls in our CVS tree to call g_access() instead.

Add an #ifndef BURN_BRIDGES #define of g_access_rel() for source
code compatibility.

926fff03bf Add a destroy_geom method to the slice "library". 
If a slice class has no destroy_geom method, use this one.

This should allow all slicers to kldload.

db4d21ffaf Make more of the "hotspot" stuff generic: 
Give the class a way to specify the necessary action for read/delete/write:
ALLOW, DENY, START or CALL.

03b1ca36ba Time has run from the "run GEOM in userland" harness, and the new regression 
test is built to test GEOM as running in the kernel.

This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.

fd7ea6d48a Better names for struct disk elements: d_maxsize, d_stripeoffset 
and d_stripesisze;

Introduce si_stripesize and si_stripeoffset in struct cdev so we

Add stripesize and stripeoffset to providers.

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,

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

4509f96cc5 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.
