For diff reduction against NetBSD's makefs. Based on NetBSD git mirror
commit 00991aee8248.
With this change our makefs cd9660 support should be in sync up to
NetBSD commit bdae6c9dc792 ("makefs(8): Nix trailing whitespace.").

Refactor daemon to use kqueue/kevent instead of signals.
This changes allows to simplify the code in several ways:
- the execution flow is now linear, no async events.
- several variables became redundant and got removed.
- all event handling is now concentrated inside of the event loop, which
makes code reading and comprehension easier.
- new kqueuex(2) call is used for CLOEXEC, but maintained closing the
kq fd prior to execve() to ease later MFC
No UX/API changes are intended.

Most register of the PCI header are either constant values or require
emulation anyway. The command and status register are the only exception which
require hardware access. So, we're adding an emulation handler for all
other register.
As this emulation handler will be reused by some future features like
GPU passthrough, we directly export it.

GPU passthrough requires a special handling of some PCI config register.
Therefore, we need a flexible approach for implementing it. Adding an
array of handler meets this condition.
Start by using the default handler for all accesses to the PCI config
space. In upcoming commits, we can start to split the default handler
into several handler for each register that requires emulation.

Some SAS JBODs support zoning. This feature allows individual SAS
targets to be accessible by only some initiator ports. One application
would be connecting two servers to the same JBOD, but they wouldn't be
able to see each other's disks.
A zoned JBOD should also prohibit initiators from accessing SES elements
corresponding to inaccessible SAS targets. It reports that by setting
the element's status code to 0x8 (No Access Allowed).
The bug is that when doing "sesutil (fault|locate) all ...", sesutil
will attempt a ENCIOC_SETELMSTAT ioctl for every single element, even
the inaccessible ones. The enclosure will reject the command, the
kernel will return EINVAL, and sesutil will exit.
The solution is to check the element's status, and skip trying to set it
if the status is 0x8. But if the user actually supplied a ses ID, then
assume that he knows what he's doing and try to set it anyway.

The Intel GOP driver checks the LPC IDs to detect the platform it's
running on. The GOP driver only works on the platforms it's written for.
Maybe other Intel driver have the same behaviour. For that reason, we
should use the LPC IDs of the FreeBSD host for GPU passthrough to work
properly.
We don't know if setting different LPC IDs have any side effect.
Therefore, don't use the host LPC IDs by default on Intel system. Give
the user the opportunity to modify the LPC IDs.

Changing the PCI IDs is valuable in some situations. The Intel GOP
driver requires that some PCI IDs of the LPC bridge are aligned with the
physical values of the host LPC bridge. Another use case are oracles
virtio driver. They require different subvendor ID than the default one.
For that reason, create a helper which makes it easy to read PCI IDs
from bhyve config. Additionally, this helper ensures that all emulation
devices are using the same config keys.

We previously attempted to emit Rock Ridge NM records only when the name
represented by the Rock Ridge extensions would actually differ. We would
omit the record for an all-upper-case directory name, however Linux (and
perhaps other operating systems) map names with no NM record to
lowercase.
This affected only directories, as file names have an implicit ";1"
version number appended and thus always differ. To solve, just emit NM
records for all entries other than DOT and DOTDOT .
We could continue to omit the NM record for directories that would avoid
mapping (for example, one named 1234.567) but this does not seem worth
the complexity.

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.
