We can now change the vlan ID of an if_vlan interface without
disassociating it from the parent interface.
Test that this works.

The setvlantag() and setvlanproto() functions are used in two scenarios:
when we create a new vlan interface and when we update an existing
interface.
These are distinguished by the getvlan() at the end of the functions. If
this fails we assume that is because the interface doesn't exist (so
we're creating a new one). We only update the 'params' struct, and
expect the settings to be applied when we vlan_create().
However, if we're updating an existing interface we do not retrieve the
current settings, and can end up invalidating settings.
Fix this by using the settings we retrieved while checking which
scenario we're in.
Note that we do not address this for setvlandev(), because if_vlan does
not allow the vlan parent device to be changed without disassociating it
first (with ifconfig vlanX -vlandev).

It's currently not possible to change the vlan ID or vlan protocol (i.e.
802.1q vs. 802.1ad) without de-configuring the interface (i.e. ifconfig
vlanX -vlandev).
Add a specific flow for this, allowing both the protocol and id (but not
parent interface) to be changed without going through the '-vlandev'
step.

libnv and libnvpair have aliased symbols, and as a result a single process which
dlopens a shared object that is dynamically linked to libnv and another to
libnvpair will wind up with a single set of resolved symbols for those in
conflict. A source file also cannot include both libnv and libnvpair headers
because of aliased identifiers. To resolve the situation, libnv types and
functions are namespaced via nv_namespace.h, and libnv symbols are
versioned. The msgio functions are not namespaced or exported as they are not
part of the external API.

Commit efe58855f3 allowed the net.inet.ip.loopback_prefix value
to be 32. However, with a 32-bit mask, 127.0.0.1 is not included
in the reserved loopback range, which should not be allowed.
Change the max prefix length to 31.

In the extremely unlikely case that the iommu_gas_map_region() call in
bus_dma_iommu_load_ident() failed, we would attempt to unmap the failed
entry twice, first in iommu_gas_map_region(), and a second time in the
caller. Once is enough, and twice is problematic because it leads to a
second RB_REMOVE call on the same tree node. Like it or not, RB_TREE
does not handle that possibility.

A better fix to commit 9e1f44d044. Rather than coping with the case
where a backup superblock is used, catch the case when the superblock
is being read in and ensure that the standard one is used rather than
the backup one.
Only the UFS2 filesystem has support for storing information needed
to find alternate superblocks. If that information is inadvertently
left in place when building a UFS1 filesystem, fsck_ffs may stumble
across it and attempt to use it to recover the UFS1 filesystem
which can only end poorly.
This fixes the build of at least i386 MINIMAL which was failing with
the error:

Allow cuse(3) to make allocations that span multiple banks at the expense
of any fragmentation issues that may arise. Typically mmap(2) buffers are

We periodically ingest entropy from pollable entropy sources, but only
8 bytes at a time and only occasionally enough to feed all of Fortuna's
pools once per second. This can result in Fortuna remaining unseeded
for a nontrivial amount of time when there is no entropy passed in from
the boot loader, even if RDRAND is available to quickly provide a large
amount of entropy.
Detect in random_sources_feed if we are not yet seeded, and increase the
amount of immediate entropy harvesting we perform, in order to "fill"
Fortuna's entropy pools and avoid having
random: randomdev_wait_until_seeded unblock wait
stall the boot process when entropy is available.
This speeds up the FreeBSD boot in the Firecracker VM by 2.3 seconds.

As Hanyong/Hancha keys are generally greater than 0x80, which is
generally considered a release key, add extra preceding press key event
to generate press/release pair.
