Fix setting/getting users/groups in quota properties through
numeric identifier. This support was accidentally disabled
in the original port by applying the HAVE_IDMAP wrapper macro
too broadly.
Fix obtained by moving #ifdef HAVE_IDMAP to exclude only
the part of code that really needs IDMAP. Now zfs (get|set)
(user|group)quota@1000 works as expected.

This commit modifies the user to kernel space ioctl ABI. Extra
care should be taken when updating to ensure both the kernel
modules and utilities are updated. This change has reordered
all of the new ioctl()s to the end of the list. This should
help minimize this issue in the future.

FreeBSD #xxx: Dramatically optimize listing snapshots when user
requests only snapshot names and wants to sort them by name, ie.
when executes:
# zfs list -t snapshot -o name -s name
Because only name is needed we don't have to read all snapshot
properties.
Below you can find how long does it take to list 34509 snapshots
from a single disk pool before and after this change with cold and
warm cache:
before:
# time zfs list -t snapshot -o name -s name > /dev/null
cold cache: 525s
warm cache: 218s
after:
# time zfs list -t snapshot -o name -s name > /dev/null
cold cache: 1.7s
warm cache: 1.1s
NOTE: This patch only appears in FreeBSD. If/when Illumos picks up
the change we may want to drop this patch and adopt their version.
However, for now this addresses a real issue.

Issue #450
When failing to remove a zvol device link because it's busy, wait
a bit and retry in a loop instead of giving up immediately. This
technique is similar to the loop in zpool_label_disk_wait(), with
the same goal: waiting for the asynchronous udev processes to finish
their work.

While setting/getting userquota and groupquota properties, the input
was not treated as a possible username or groupname if it had a
leading digit. While useradd in linux recommends the regexp
[a-z_][a-z0-9_-]*[$]? , it is not enforced. This causes problem for
usernames with leading digits in them. We need to be able to support
getting and setting properties for this unconventional but possible
input category
I've updated the code to validate the username or groupname directly
via the API. Also, note that I moved this validation to the beginning
before the check for SID names with @. This also supports usernames
with @ character in them which are valid. Only when input with @ is
not a valid username, it is interpreted as a potential SID name.

Add a "REFRATIO" property, which is the compression ratio based on
data referenced. For snapshots, this is the same as COMPRESSRATIO,
but for filesystems/volumes, the COMPRESSRATIO is based on the
data "USED" (ie, includes blocks in children, but not blocks
shared with the origin).
This is needed to figure out how much space a filesystem would
use if it were not compressed (ignoring snapshots).

Issue #340
The .get_sb callback has been replaced by a .mount callback
in the file_system_type structure. When using the new
interface the caller must now use the mount_nodev() helper.
Unfortunately, the new interface no longer passes the vfsmount
down to the zfs layers. This poses a problem for the existing
implementation because we currently save this pointer in the
super block for latter use. It provides our only entry point
in to the namespace layer for manipulating certain mount options.
This needed to be done originally to allow commands like
'zfs set atime=off tank' to work properly. It also allowed me
to keep more of the original Solaris code unmodified. Under
Solaris there is a 1-to-1 mapping between a mount point and a
file system so this is a fairly natural thing to do. However,
under Linux they many be multiple entries in the namespace
which reference the same filesystem. Thus keeping a back
reference from the filesystem to the namespace is complicated.
Rather than introduce some ugly hack to get the vfsmount and
continue as before. I'm leveraging this API change to update
the ZFS code to do things in a more natural way for Linux.
This has the upside that is resolves the compatibility issue
for the long term and fixes several other minor bugs which
have been reported.
This commit updates the code to remove this vfsmount back
reference entirely. All modifications to filesystem mount
options are now passed in to the kernel via a '-o remount'.
This is the expected Linux mechanism and allows the namespace
to properly handle any options which apply to it before passing
them on to the file system itself.
Aside from fixing the compatibility issue, removing the
vfsmount has had the benefit of simplifying the code. This
change which fairly involved has turned out nicely.
