Add property and sysctl to control how ZVOLs are exposed to OS.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
geom -- existing fully functional behavior (default);
dev -- exposing volumes only as raw disk device file in devfs;
none -- not exposing volumes outside ZFS.
The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.
Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

Instead of rereading VPD pages on every device open, do it only on initial

it is more critical for operation and more probable to change in run time.

Add support for SCSI UNMAP commands to CTL.
This patch adds support for three new SCSI commands: UNMAP, WRITE SAME(10)
and WRITE SAME(16). WRITE SAME commands support both normal write mode
and UNMAP flag. To properly report UNMAP capabilities this patch also adds
support for reporting two new VPD pages: Block limits and Logical Block
Provisioning.
UNMAP support can be enabled per-LUN by adding "-o unmap=on" to `ctladm
create` command line or "option unmap on" to lun sections of /etc/ctl.conf.
At this moment UNMAP supported for ramdisks and device-backed block LUNs.
It was tested to work great with ZFS ZVOLs. For file-backed LUNs UNMAP
support is unfortunately missing due to absence of respective VFS KPI.

When the kernel is running in a virtual machine, it cannot rely upon the
processor family to determine if the workaround for AMD Family 10h Erratum
383 should be enabled. To enable virtual machine migration among a
heterogeneous collection of physical machines, the hypervisor may have
been configured to report an older processor family with a reduced feature
set. Effectively, the reported processor family and its features are like
a "least common denominator" for the collection of machines.
Therefore, when the kernel is running in a virtual machine, instead of
relying upon the processor family, we now test for features that prove
that the underlying processor is not affected by the erratum. (The
features that we test for are unlikely to ever be emulated in software
on an affected physical processor.)
