describe the effective (usable) storage of that partition.

might do subsequent reads from other providers. This stopped geli (and
probably other classes using g_metadata_store as well) from being put on top
of gvinum raid5 volumes.
Note:
The reason it fails in the gvinum raid5 case is that gvinum will read back the
old parity stripe before calculating the new parity stripe to be written out
again. The write will then fail because the underlying disk to be read is
opened write only.

formatting a number in a human-friendly way.
Note that with this commit a megabyte changed from 1000000 to
1048576 and a 80G disk is now printed as being 75G in size.
This is deliberate. It's consistent with the core of geom(8).
However, the original choice for a megabyte being 1000000 was
on purpose and matches what disk vendors put on the box. The
consistency is considered more important.

Option '-B none' can by used to prevent backup. Option '-B path' can be
used to backup metadata to a different file than the default, which is
/var/backups/<prov>.eli.
The 'geli init' command also prints backup file location and gives short
procedure how to restore metadata.
The 'geli setkey' command now warns that even after passphrase change or keys
update there could be version of the master key encrypted with old
keys/passphrase in the backup file.
Add regression tests to verify that new functionality works as expected.
Update other regression tests so they don't create backup files.

RELEASE_CRUNCH builds use NO_MAN anyway, so this change is primarily
to avoid that developers have to set NO_MAN manually when they build
the static variant.
The -l option changes the output to show the partition label, if applicable
and when present. The -r option changes the output to show the raw (i.e.
scheme-specific) partition types.

by geom(8) itself and which should not be passed to the kernel.
o gctl_has_param() -- intended to check if optional parameters are
present.
Both are needed by gpart(8) to process the optional parameter for
writing bootcode to a partition (as part of the bootcode verb).
However, the kernel is itself not involved in this matter and the
parameter needs to be removed from the request destined for the
kernel.

geom can more easily be part of other crunched binaries, as it requires
