e84091cb52 For arguments declared as numbers always use expand_number(3).
This allows to use numbers in human-readable form in many geom(8)
utilities. Such a simple change and makes live so much nicer.
Some examples:

	gstripe label -s 16k
	gmirror label -s 4k
	gnop create -o 1g -s 128m -S 2k
	gjournal label -s 2g
	geli label -i 128k -s 4k

cf805fab87 Fix the construction of the gctl_req that got broken by my
previous commit and that introduced optional parameters.
Existing classes (like geli(8)) use empty strings by default
and expect the parameter to be passed to the kernel as such.
Also, the default value of a string argument can be NULL.
Fix both cases by making the optional parameter conditional
upon gc_argname being set and making sure to test for NULL
before dereferencing the pointer.

3cf55d3ab9 Add gpart(8).
In order to support gpart(8), geom(8) needs to support a named
argument. Also, optional string parameters are a requirement.
Both have been added to the infrastructure. The former required
all existing classes to be adjusted.

e770bc6bf5 First cut at GEOM based multipath. This is an active/passive{/passive...}
arrangement that has no intrinsic internal knowledge of whether devices
it is given are truly multipath devices. As such, this is a simplistic
approach, but still a useful one.

The basic approach is to (at present- this will change soon) use camcontrol
to find likely identical devices and and label the trailing sector of the
first one. This label contains both a full UUID and a name. The name is
what is presented in /dev/multipath, but the UUID is used as a true
distinguishor at g_taste time, thus making sure we don't have chaos
on a shared SAN where everyone names their data multipath as "Fred".

The first of N identical devices (and N *may* be 1!) becomes the active
path until a BIO request is failed with EIO or ENXIO. When this occurs,
the active disk is ripped away and the next in a list is picked to
(retry and) continue with.

During g_taste events new disks that meet the match criteria for existing
multipath geoms get added to the tail end of the list.

Thus, this active/passive setup actually does work for devices which
go away and come back, as do (now) mpt(4) and isp(4) SAN based disks.

There is still a lot to do to improve this- like about 5 of the 12
recommendations I've received about it,  but it's been functional enough
for a while that it deserves a broader test base.

eeefa1fa7e When the following conditions are meet:
- First configured key is based only on keyfile (no passphrase).
- Device is attached.
- User changes first key (setkey) from keyfile to passphrase and doesn't
  specify number of iterations (with -i option).
...geli(8) won't store calculated number of iterations in metadata.
This result in device beeing unaccesable after detach.

One can recover from this situation by guessing number of iterations
generated, storing it in metadata and trying to attach device.
Recovery procedure isn't nice, but one's data is not lost.

04c7da702f A GEOM cache can speed up read performance by sending fixed size
read requests to its consumer.  It has been developed to address
the problem of a horrible read performance of a 64k blocksize FS
residing on a RAID3 array with 8 data components, where a single
disk component would only get 8k read requests, thus effectively
killing disk performance under high load.  Documentation will be
provided later.  I'd like to thank Vsevolod Lobko for his bright
ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.

- Add some assertions.
- Bump version number, because G_TYPE_BOOL addition breaks API and ABI.

- after killing all attached providers, all providers are then detached
