Highlights:
- Exit early if we're not disabling unused regulators; there's no need to
take the regulator topology lock and re-evaluate this every iteration, as
it's not going to change.
- Don't emit a notice that we're shutting down a regulator if it's not
enabled, to reduce noise.
- Mention the outcome of the shutdown, to aide debugging and easily let
developer/user collect list of regulators we actually shutdown to
determine problematic one.

This creates a dedicated routine (vn_alloc) to allocate vnodes.
As a side effect code duplicationw with getnewvnode_reserve is eleminated.
Add vn_free for symmetry.
Having a reserved vnode count does not guarantee that getnewvnodes wont
block later. Said blocking partially defeats the purpose of reserving in
the first place.
Preallocate instaed. The only consumer was always passing "1" as count
and never nesting reservations.

actually broke child resource allocation, due to typos in

In the code we used NumClusters as the upper (non-inclusive) boundary
of valid cluster number, so the actual value was 2 (CLUST_FIRST) more
than the real number of clusters. This causes a FAT16 media with
65524 clusters be treated as FAT32 and might affect FAT12 media with
4084 clusters as well.
To fix this, we increment NumClusters by CLUST_FIRST after the type
determination.

Explicitly setting WITHOUT_KERBEROS implies WITHOUT_KERBEROS_SUPPORT,
but previously other cases that forced KERBEROS off (such as
WITHOUT_CRYPT) did not also set KERBEROS_SUPPORT off. Because the
_SUPPORT dependent options (KERBEROS/KERBEROS_SUPPORT) are processed
before other dependencies (CRYPT/KERBEROS) it's not easy to make this
happen automatically. Instead just explicitly set KERBEROS_SUPPORT
off where we set KERBEROS off.

The patch could be simplier, using only the second chunk to
vtnet_rxq_eof(), that passes full mbufs to pfil(9). Packet
filter would m_free() them in case of returning PFIL_DROPPED.
However, we pretend to be a hardware driver, so we first try
to pass a memory buffer via PFIL_MEMPTR feature. This is mostly
done for debugging purposes, so that one can experiment in bhyve
with packet filters utilizing same features as a true driver.

We use to handle each message separately in i2c_transfer but that cannot
work with message with NOSTOP as it confuses the controller that we disable
the interrupts and start a new message.
Handle every message in the interrupt handler and fire a new start condition
if the previous message have NOSTOP, the controller understand this as a
repeated start.
This fixes booting on Allwinner A10/A20 platform where before the i2c controller
used to write 0 to the PMIC register that control the regulators as it though that
this was the continuation of the write message.

When either makesyscalls.lua or syscalls.master changes, all of the
${GENERATED} targets are now out-of-date. With make jobs > 1, this means we
will run the makesyscalls script in parallel for the same ABI, generating
the same set of output files.
Prior to r356603 , there is a large window for interlacing output for some
of the generated files that we were generating in-place rather than staging
in a temp dir. After that, we still should't need to run the script more
than once per-ABI as the first invocation should update all of them. Add
.ORDER to do so cleanly.

This makes makesyscalls.lua more parallel-friendly, or at least not as
hostile to the idea. We get into situations where we're running parallel if
we end up with MAKE_JOBS>1 entering any of the sysent targets, since each
output file is recognized a distinct build step that needs to be executed.
Another commit will add some .ORDER to further improve the situation.

It may be possible to make this completely lock free, but for now it's using

The newer versions of RPi FDT flipped the order of the interrupts
specification and added an 'interrupt-names' property for driver aide in
finding the correct interrupt, rather than assuming the positions. Use it if
it's available, or fallback to the old method if there is no interrupt-names
property with a usb value.
This has been tested with both old RPi3B FDT and new RPi3B FDT, USB again
works on the latter.

Some kernel subsystems, notably ZFS, will destroy UMA zones from a
shutdown eventhandler. This causes the zone to be drained. For slabs
that are mapped into KVA this can be very expensive and so it needlessly
delays the shutdown process.
Add a new state to the "booted" variable, BOOT_SHUTDOWN. Once
kern_reboot() starts invoking shutdown handlers, turn uma_zdestroy()
into a no-op, provided that the zone does not have a custom finalization
routine.

soft do floating point calcuations without using floating point
hardware. Pass arguments in integer registers.
FreeBSD 11 and newer assumes hard. 10 and earlier assumed softfp. We have no
real support, at the moment, for soft. It's untested, though, if softfp still
works.
Add a note here since this is a whack-a-doodle combination relative to all other
platforms.
softfp is likely to go away in the future because it was retained for people
using FreeBSD 10 + armv6 needing to transition more slowly from softfp -> hard
than the project. It likely is no longer needed, and may be getting in the
way of people needing 'soft' support.
Having metadata such as fibnum or vnet in the struct rib_head
is handy as it eases building functionality in the routing space.
