8cc5eb98ad Fix a stupid logic bug introduced in geom_vinum_drive.c rev 1.18: 
When a drive is newly created, it's state is initially set to 'down',
so it won't allow saving the config to it (thus it will never know of
itself being created).  Work around this by adding a new flag, that's
also checked when saving the config to a drive.

4ed854e8d4 Use root_mount KPI for RAID3 to delay root file system mount. 
Actually, one cannot setup root file system on RAID3 device, but when
other file system exist in /etc/fstab which are placed on RAID3 device,
boot process will be interrupted when these devices are missing.

8827c821de By design I left a tiny race in updating the I/O statistics based on 
the assumption that performance was more important that beancounter
quality statistics.

As it transpires the microoptimization is not measurable in the
real world and the inconsistent statistics confuse users, so revert
the decision.

565bc10111 Add a very simple and small GEOM class - ZERO. 
It creates very huge provider (41PB) /dev/gzero.
On BIO_READ request it zero-fills bio_data and on BIO_WRITE it does nothing.
You can also set kern.geom.zero.clear sysctl to 0 to do nothing even for
BIO_READ.

I'm using it for performance testing where it is very helpful.

d5e3d722df The size of a filesystem may be less than the size of the provider it 
resides on.  Fix the special case of the filesystem fragment size not
evenly dividing the size of the provider.  Fixing the general case
probably requires better superblock validation (left as an exercise to
the reader).

d1c712ede2 Call g_waitidle() instead of GEOM using the root_mount_hold() KPI. 
GEOM could (and will) get events as a result of drivers coming in
late so a one-shot method is not good enough for GEOM.

73fbaa74e5 Add a named reference-count KPI to hold off mounting of the root filesystem. 
While we wait for holds to be released, print a list of who holds us
back once per second.

Use the new KPI from GEOM instead of vfs_mount.c calling g_waitidle().

Use the new KPI also from ata.

With ATAmkIII's newbusification, ata could narrowly miss the window
and ad0 would not exist when we tried to mount root.

811787079b Protect against recursive labels creation in simlar way as it is done 
in BSD and MBR classes, ie. if provider below us uses the same metadata,
don't create labels based on the metadata.
This allows to create labels on geoms with rank != 1 without hacks.
