This is a userland-only pointer that isn't relevant to the kernel and
doesn't belong in the ioctl structure shared between userland and the
kernel. For the kernel, the old structure for the ioctl is still
supported under COMPAT_FREEBSD13.
This changes vm_snapshot_req() in libvmmapi to accept an explicit
vmctx argument.
It also changes vm_snapshot_guest2host_addr to take an explicit vmctx
argument. As part of this change, move the declaration for this
function and its wrapper macro from vmm_snapshot.h to snapshot.h as it
is a userland-only API.

This replaces the 'struct vm, int vcpuid' tuple passed to most API
calls and is similar to the changes recently made in vmm(4) in the
kernel.
struct vcpu is an opaque type managed by libvmmapi. For now it stores
a pointer to the VM context and an integer id.
As an immediate effect this removes the divergence between the kernel
and userland for the instruction emulation code introduced by the
recent vmm(4) changes.
Since this is a major change to the vmmapi API, bump VMMAPI_VERSION to
0x200 (2.0) and the shared library major version.
While here (and since the major version is bumped), remove unused
vcpu argument from vm_setup_pptdev_msi*().
Add new functions vm_suspend_all_cpus() and vm_resume_all_cpus() for
use by the debug server. The underyling ioctl (which uses a vcpuid of
-1) remains unchanged, but the userlevel API now uses separate
functions for global CPU suspend/resume.

This reverts the state to our old supplicant logic setting or clearing
IFF_UP if needed. In addition this adds logging for the cases in which
we do (not) change the interface state.
Depending on testing this seems to help bringing WiFi up or not log
any needed changes (which would be the expected wpa_supplicant logic
now). People should look out for ``(changed)`` log entries (at least
if debugging the issue; this way we will at least have data points).
There is a hypothesis still pondered that the entire IFF_UP toggling
only exploits a race in net80211 (see further discssussions for more
debugging and alternative solutions see D38508 and D38753).
That may also explain why the changes to the rc startup script [1]
only helped partially for some people to no longer see the
continuous CTRL-EVENT-SCAN-FAILED.
It is highly likely that we will want further changes and until
we know for sure that people are seeing ''(changed)'' events
this should stay local. Should we need to upstream this we'll
likely need #ifdef __FreeBSD__ around this code.

This entails:
- Marking some obvious candidates for __nosanitizeaddress
- Similar trap frame markings as amd64, for similar reasons
- Shadow map implementation
The shadow map implementation is roughly similar to what was done on
amd64, with some exceptions. Attempting to use available space at
preinit_map_va + PMAP_PREINIT_MAPPING_SIZE (up to the end of that range,
as depicted in the physmap) results in odd failures, so we instead
search the physmap for free regions that we can carve out, fragmenting
the shadow map as necessary to try and fit as much as we need for the
initial kernel map. pmap_bootstrap_san() is thus after
pmap_bootstrap(), which still included some technically reserved areas
of the memory map that needed to be included in the DMAP.
The odd failure noted above may be a bug, but I haven't investigated it
all that much.

It was previously possible for the fault address register to get
clobbered before it was saved. This small window occurred when an
additional exception was encountered inside the exception handler,
overwriting the previous value.
Commit f29942229d ("Read the arm64 far early in el0 exceptions")
patched this issue, but avoided changing the trapframe since this could
be considered a KBI change in FreeBSD 13.
Revert the above fix and save the fault address in the trapframe
instead. This saves the fault address even earlier in the exception
handling process, and is a more robust and simple fix.

Summary:
Sometimes an if_foreach() callback can be trivial, or need a lot of
outer context. In this case a regular `for` loop makes more sense. To
keep things hidden in the new API, use an opaque `if_iter` structure
that can still be instantiated on the stack. The current implementation
uses just a single pointer out of the 4 alotted to the opaque context,
and the cleanup does nothing, but may be used in the future.
