Some fixes:
- Maintain historical behavior more accurately w.r.t verbose_loading;
verbose_loading strictly prints "${module_name...}" and later "failed!"
or "ok" based on load success
- With or without verbose_loading, dump command_errbuf on load failure.
This usually happens prior to ok/failed if we're verbose_loading

Use userboot.so from the test directory if possible, fall back to .OBJDIR.
This avoids a problem that we've had since userboot coexistence was added,
where userboot.so alone no longer exists in the .OBJDIR but is instead just
a link installed later.
There are multiple ways to wait for any child process to return a
status (e.g., waitpid(-1, ...), waitid(P_ALL, ...)), so don't be so
specific.

Previously, it used a hand-rolled round-robin iterator. This meant that
the minskip logic in r338507 didn't apply to UMA allocations, and also
meant that we would call vm_wait() for individual domains rather than
permitting an allocation from any domain with sufficient free pages.

Currently, a timeout in the menu autoboot sequence would effectively do
nothing. We would return from the autoboot handling, then begin processing
the menu without redrawing it.
This change makes the behavior a little more friendly. Returning the user to
the menu can't have any good effects, so abort the autoboot sequence and
drop to the loader prompt.

In the majority of cases, a kernel is not loaded before we hit the menu.
However, if a password is set, we'll trigger autoboot and have loadelf'd
beforehand. We also need to take into account one dropping to the loader
prompt and twiddling with things manually; if they try to toggle through
kernels, we'll assume they mean it.

ffs_subr.c requires calculate_crc32c() from libkern. Unfortunately we
cannot just add libkern/crc32.c to libstand because crc32.o is already
compiled from contrib/zlib/crc32.c. Use the include trick to rename
the source.
Note that libstand also provides crc32.c which seems to be unused.

Use bypass to catch any NFS VOP dispatch and route it through the
wrapper which does sigdeferstop() and then dispatches original
VOP. NFS does not need a bypass below it, which is not supported.
The vop offset in the vop_vector is added since otherwise it is
impossible to get vop_op_t from the internal table, and I did not
wanted to create the layered fs only to wrap NFS VOPs.
VFS_OP()s wrap is straightforward.

check hash to the superblock. If a check hash fails when an attempt
is made to mount a filesystem, the mount fails with EINVAL (Invalid
argument). This avoids a class of filesystem panics related to
corrupted superblocks. The hash is done using crc32c.
Check hases are added only to UFS2 and not to UFS1 as UFS1 is primarily
used in embedded systems with small memories and low-powered processors
which need as light-weight a filesystem as possible.

Before this change we had two flavours of vm_domainset iterators: "page"
and "malloc". The latter was only used for kmem_*() and hard-coded its
behaviour based on kernel_object's policy. Moreover, its use contained
a race similar to that fixed by r338755 since the kernel_object's
iterator was being run without the object lock.
In some cases it is useful to be able to explicitly specify a policy
(domainset) or policy+iterator (domainset_ref) when performing memory
allocations. To that end, refactor the vm_dominset_* KPI to permit
this, and get rid of the "malloc" domainset_iter KPI in the process.

In current tftp code we drop out-of-order packets; however, we should play

ingress address checking subsystem isn't VNET specific. And thus
callback can make access to already freed memory. To prevent this,
