a92b7d4982 - Be more verbose when saying "foo" not found. 
- In gctl_get_geom(), don't issue error when we were not
   provided with an parameter, like gctl_get_provider() did.

41063f9380 Change gctl_set_param() to return an error instead of setting an 
error on the request.  Add a wrapper, gctl_set_param_err(), that
sets the error on the request from the error returned by
gctl_set_param() and update current callers of gctl_set_param()
to call gctl_set_param_err() instead.
This makes gctl_set_param() much more usable in situations where
the caller knows better what to do with certain (apparent) error
conditions and setting an error on the request is not one of the
things that need to be done.

40fcaded53 o Don't cause a panic when the control request lacks a verb. 
o  Don't set the error twice when the named class does not exist.
   It causes ioctl(2) to return with error EEXIST.

e8cde1ac6f Discontinue zero-length g_ctl arguments as "just give him this pointer" 
transfers.  The necessary context for calling copyin() isn't available
anyway and automatic code-validation chokes on this.

dc08ffec87 Device megapatch 4/6: 
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

70cd771337 The present defaults for the open and close for device drivers which 
provide no methods does not make any sense, and is not used by any
driver.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.

Change the defaults to be nullopen() and nullclose() which simply
does nothing.

Remove explicit initializations to these from the drivers which
already used them.

83d771de78 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 changed parameters
back when done.

afa2a5aab7 Remove some debugging in the new OAM[*] and add a debug flag for other 
parts of it.

[*] I've been asked what "OAM" means:  It's an acronym used in the
telecom industry, "Operations And Maintenance", and there it covers
anything from a single unlabeled led on the frontpanel the the full
nightmare of CMIP for SS7.

3f12caa180 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.
