This is a follow up commit for e03a41a60 which aimed to resolve
this same test failure. The core "problem" here is that it takes
very little space to perform a clone/snapshot/bookmark, which
means if we want these commands to reliably fail the pool must
truely have exhausted all free space.
This commit increases the number of fill iterations to try and
consume every block which we can. This still can't guarantee
the clone/snapshot/bookmark will fail, but it significantly
improves the odds. The exception was kept since it's still
not a sure thing.

On FreeBSD vnode reclamation is single-threaded, protected by single
global lock. Linux seems to be able to use a thread per mount point,
but at this time it creates more harm than good.
Reduce number of threads to 1, adding tunable in case somebody wants
to try more.

Issue #9966
Under Linux when rolling back a mounted filesystem negative dentries
may not be dropped from the cache. This can result in an ENOENT
being incorrectly returned on first access. Issuing a `df` before
the unmount results in the negative dentries being invalidated and
side steps the issue.
This is solely a workaround for the test case on Linux and not
correct behavior. The core issue of invalidating negative dentries
needs to be handled with a kernel side change. This is being
tracked as issue #6143.

With some minor tweaks several of rsend tests can be sped up
considerably without significantly reducing test coverage.
* send-c_verify_ratio: ~120s -> ~60s
* send_realloc_*_files: ~330s -> ~65s
For the send_realloc* tests this also has the advantage of removing
(most of) the linux/freebsd conditional logic. Note that for this
test more passes, and thus more incremental send/recvs, are preferable
to a larger number of files.
Total run time of the rsend test group was reduced from roughly 20 to
11 minutes in an environment similar to what's used by the CI.

The rsend_007_pos test reliably fails on Linux in the cleanup
function. This is caused by an unmount error when attempting to
recursively destroy the newly received datasets. Invoking `df`
prior to the `zfs destroy` interestingly avoids the unmont error.
Why this should matter is unclear and should be investigated.
However, this minor tweak may allow us to remove the ZTS rsend
exceptions. The subsequent rsend_010_pos and rsend_011_pos
failures were a result of this initial failure. The other
"maybe" failures I was unable to reproduce and have not been
recently observed in the master branch.

When restructuring the zvol_open() logic for the Linux 5.13 kernel
a lock inversion was accidentally introduced. In the updated code
the spa_namespace_lock is now taken before the zv_suspend_lock
allowing the following scenario to occur:
down_read <=== waiting for zv_suspend_lock
zvol_open <=== holds spa_namespace_lock
__blkdev_get
blkdev_get_by_dev
blkdev_open
...
mutex_lock <== waiting for spa_namespace_lock
spa_open_common
spa_open
dsl_pool_hold
dmu_objset_hold_flags
dmu_objset_hold
dsl_prop_get
dsl_prop_get_integer
zvol_create_minor
dmu_recv_end
zfs_ioc_recv_impl <=== holds zv_suspend_lock via zvol_suspend()
zfs_ioc_recv
...
This commit resolves the issue by moving the acquisition of the
spa_namespace_lock back to after the zv_suspend_lock which restores
the original ordering.
Additionally, as part of this change the error exit paths were
simplified where possible.

If sufficient memory (<2K, realistically) is available, libzfs_init()
can be significantly shorted by iterating over the correct sysfs
directory before registrations, we can turn 168 stats into 15/18
syscalls (3 opens (6 if built in), 3 fstats, 6 getdentses, and 3
closes), a tenfoldish reduction; this is probably a bit faster, too.
The list is always optional, and registration functions (and one-off
users) can simply pass NULL, which will fall back to the previous
mechanism
Also, don't allocate in zfs_mod_supported_impl, and use use access()
instead of stat(), since existence is really what we care about
