KASSERT against multiple orphanings of providers.

Re-arrange and consolidate some random debugging stuff

Introduce a per provider wither flag

Simplify the ioctl handling in GEOM.

This replaces the current ioctl processing with a direct call path
from geom_dev() where the ioctl arrives (from SPECFS) to any directly
connected GEOM class.

Simplify the ioctl handling in GEOM.

This replaces the current ioctl processing with a direct call path
from geom_dev() where the ioctl arrives (from SPECFS) to any directly
connected GEOM class.

The inverse of the above is no longer supported. This is the
situation were you have one or more intervening GEOM classes, for
instance a BSDlabel on top of a MBR or PC98. If you want to issue
MBR or PC98 specific ioctls, you will need to issue them on a MBR
or PC98 providers.

This paves the way for inviting CD's, FD's and other special cases
inside GEOM.

Add the new g_dev_getprovider() function, the swap_pager needs it now.

Improve the root-dev prompt facility for printing devices which could
possibly be a root filesystem.

Drop a memory-corruption debugging test-tool.

Introduce g_provider_by_name() function, and use it.

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

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

constify g_sanity()

Introduce a init and fini member functions on a class.

Use ->init() and ->fini() to handle the mutex in geom_disk.c

Remove the g_add_class() function and replace it with a standardized
g_modevent()

Remove the g_add_class() function and replace it with a standardized
g_modevent() function.

This adds the basic infrastructure for loading/unloading GEOM classes

Remove the G_CLASS_INITIALIZER, we do not need it anymore.

Add gctl_set_param() function.

Rework the "withering" mechanism:

Introduce g_wither_geom() to do the work in one single place.

Remove the now obsolete geomidorname hack.

Introduce a g_waitfor_event() function which posts an event and waits for
it to be run (or cancelled) and use this instead of home-rolled versions.

Rename g_call_me() to g_post_event(), and give it a flag
argument to determine if we can M_WAITOK in malloc.

Make gctl_error() take printfline varargs.

Remove unused event pointers in object structures.
Remove KASSERTS which checked that they were unused.

Implement handling of CONFIG_GEOM OAM request.

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.

Remove all references to BIO_SETATTR. We will not be using it.

Remove geom_enc.c, a superset of these functions are now available in
<sys/endian.h>

Add handling for cancelled events in the g_call_me() methods.
