in6.h: expose s6_addr* definitions to user level
The only element of of in6_addr that is specified in RFC 3493 or
in POSIX.1-2017 is s6_addr, implemented via a #define to a union
member. However, FreeBSD and other BSD systems have additional
definitions for the other union members, s6_addr{8,16,32} which
are defined for the kernel and loader. Some Linux applications
also use them, and they seem to be allowed by the RFC and POSIX.
Remove the current ifdefs, exposing the additional fields to user
level, and replace with #if __BSD_VISIBLE. Add an explanatory
comment expanding on the previous "nonstandard" comment.

kthread: Set *tdptr earlier in kproc_kthread_add()
See commit ae77041e0714 ("kthread: Set *newtdp earlier in
kthread_add1()") for details. That commit was incomplete since
g_init()'s first call to kproc_kthread_add() will cause
kproc_kthread_add() to take the `*procptr == NULL` branch, which avoids
kthread_create().
To ensure that the thread pointer is initialized before the thread
starts running, we have to start the kernel process with RFSTOPPED.
We could perhaps go further and use RFSTOPPED only when tdptr != NULL,
but it's probably better to have consistent behaviour.

arm64: Check DMAP address is valid in PHYS_IN_DMAP
When checking if a physical address is in the DMAP region we assume
all physical addresses between DMAP_MIN_PHYSADDR and DMAP_MAX_PHYSADDR
are able to be accesses through the DMAP. It may be the case that
there is device memory in this range that shouldn't be accessed through
the DMAP mappings.
Add a check to PHYS_IN_DMAP that the translated virtual address is a
valid kernel address. To support code that already checks the address
is valid add PHYS_IN_DMAP_RANGE.

krpc: Ref cnt the client structures for TLS upcalls
A crash occurred during testing, where the client structures had
already been free'd when the upcall thread tried to lock them.
This patch acquires a reference count on both of the structures
and these are released when the upcall is done, so that the
structures cannot be free'd prematurely. This happened because
the testing is done over a very slow vpn.
Found during a IETF bakeathon testing event this week.

guestrpc module to handle VMware backdoor port GuestRPC functionality
Convert existing FreeBSD vmware_hvcall function to take a channel
and parameter arguments.
Added vmware_guestrpc_cmd() to send GuestRPC commands to the VMware
hypervisor. The sbuf argument is used for both the command to send
and to store the data to return to the caller.
The following KPIs can be used to get and set FreeBSD-specific guest
information in key/value pairs:
* vmware_guestrpc_set_guestinfo
- set a value into the guestinfo.fbsd.<keyword> key
* vmware_guestrpc_get_guestinfo
- get the value stored in the guestinfo.fbsd.<keyword> key

bhyve: Move lock of uart frontend to uart backend
Currently, lock of uart in bhyve is placed in frontend. There are some
problems about it:
1. If every frontend should has a lock, why not move it inside backend
as they all have same uart_softc.
2. If backend needs to modify the information of uart after initialize,
it will be impossible as backend cannot use lock. For example, if we
want implement a telnet support for uart in backend, It should wait
for connection when initialize. After some remote process connect it,
it needs to modify rfd and wfd in backend.
So I decide to move it to backend.

vmrun.sh: Add arm64 support
For now, we enumerate disk devices before network devices. This is to
work around a problem wherein u-boot remaps BARs during boot in a way
that bhyve does not handle. Some discussion and experiments suggest
that this can be handled by having bhyve not map BARs during boot on
arm64; until a solution is implemented, however, this workaround is
sufficient for simple usage and doesn't have any real downsides.
The console and bootrom are specified slightly differently versus amd64,
and a few of vmrun.sh's command-line options are amd64-only.
