psci_attach is way too late to provide the intended semantics for
psci_present. psci calls can be made immediately after psci_init(),
called way earlier at SI_SUB_CPU + SI_ORDER_FIRST, and we need it to
be valid as early as we can possibly call a psci function.
This fixes booting RPi3+4 with the in-review spintable patch;
rpi3-psci-monitor patches the FDT to add a PSCI node, but it doesn't
patch each cpus' enable-method. Because of this, we would stall the
boot while enabling CPU 1 as we saw a valid looking enable-method and
"no" functional PSCI and attempted to use the spintable rather than
simply not starting secondary APs.

Refactor the symlink and mountpoint traversal logic to avoid
repeatedly checking the vnode type; a symlink cannot be a mountpoint
and vice versa. Avoid repeatedly checking cn_flags for NOCROSSMOUNT
and simplify the check which determines whether the vnode is a
mountpoint.

These are of limited use since the crossmp vnode locking ops have not
actually used a lock since commit
a2d3554542. We in fact require that
these operations are always issued with LK_SHARED. Additionally,
these directives can produce a false positive in certain VV_CROSSLOCK
cases which require upgrading of the covered vnode lock from shared
to exclusive.
While here, replace the runtime check of LK_SHARED with a KASSERT and
expand the check to include LK_NOWAIT, which all callers pass.

When a lookup operation crosses into a new mountpoint, the mountpoint
must first be busied before the root vnode can be locked. When a
filesystem is unmounted, the vnode covered by the mountpoint must
first be locked, and then the busy count for the mountpoint drained.
Ordinarily, these two operations work fine if executed concurrently,
but with a stacked filesystem the root vnode may in fact use the
same lock as the covered vnode. By design, this will always be
the case for unionfs (with either the upper or lower root vnode
depending on mount options), and can also be the case for nullfs
if the target and mount point are the same (which admittedly is
very unlikely in practice).
In this case, we have LOR. The lookup path holds the mountpoint
busy while waiting on what is effectively the covered vnode lock,
while a concurrent unmount holds the covered vnode lock and waits
for the mountpoint's busy count to drain.
Attempt to resolve this LOR by allowing the stacked filesystem
to specify a new flag, VV_CROSSLOCK, on a covered vnode as necessary.
Upon observing this flag, the vfs_lookup() will leave the covered
vnode lock held while crossing into the mountpoint. Employ this flag
for unionfs with the caveat that it can't be used for '-o below' mounts
until other unionfs locking issues are resolved.

Older binaries that do not request IPI exits to userspace do not
start user threads for other vCPUs until a STARTUP IPI triggers a
VM_EXITCODE_SPINUP_AP exit to userland. This means that those vcpus
are not yet active (in terms of vm_active_cpus) when the INIT and
STARTUP IPIs are delivered to the vCPUs.
The changes in commit 0bda8d3e9f changed the INIT and STARTUP IPIs
to reuse the existing vlapic_calcdest() function. This function
silently ignores IPIs sent to inactive vCPUs. As a result, when using
an old bhyve binary, the INIT and STARTUP IPIs sent to wakeup APs were
ignored.
To fix, restructure the compat code for the INIT and STARTUP IPIs to
ignore the results of vlapic_calcdest() and manually parse the APIC ID
and resulting vcpuid. As part of this, make the compat code always
conditonal on the ipi_exit capability being disabled.

If the system has been up more longer than a minute, we add 30 seconds to
the uptime so that subsequent calculations will round to the nearest minute
rather than truncate. However, since the introduction of libxo, we output
the raw value after performing the adjustment. Rewrite so that we output
the raw value first, then perform the adjustment and recalculate before
outputting the humanized value.
While there, reduce stack usage and avoid needless allocations.

Avoid an out-of-bounds access when trying to set the space_char using an
international currency format (%i) and the C/POSIX locale.
The current code tries to read the SPACE from int_curr_symbol[3]:
currency_symbol = strdup(lc->int_curr_symbol);
space_char = *(currency_symbol+3);
But on C/POSIX locales, int_curr_symbol is empty.
Three implementations have been examined: NetBSD[1], Darwin[2], and
Illumos[3]. Only NetBSD has fixed it[4].
Darwin and NetBSD also trim the mandatory final SPACE character after
reading it.
