The hypervisor is aware of all system properties. For the guest bios
it's hard and complex to detect all system properties. For that reason,
it would be better if the hypervisor creates acpi tables instead of the
guest. Therefore, the hypervisor has to send the acpi tables to the
guest. At the moment, bhyve just copies the acpi tables into the guest
memory. This approach has some restrictions. You have to keep sure that
the guest doesn't overwrite them accidentally. Additionally, the size of
acpi tables is limited.
Providing a plain copy of all acpi tables by fwcfg isn't possible. Acpi
tables have to point to each other. So, if the guest copies the acpi
tables into memory by it's own, it has to patch the tables. Due to
different layouts for different acpi tables, there's no generic way to
do that. For that reason, qemu created a table loader interface. It
contains commands for the guest for loading specific blobs into guest
memory and patching those blobs.
This commit adds a qemu_loader class which handles the creation of qemu
loader commands. At the moment, the WRITE_POINTER command isn't
implement. It won't be required by bhyve's acpi table generation yet.

Rather than having a tool in the FreeBSD base system for obtaining

and then `git clone https://git.FreeBSD.org/ports.git /usr/ports`.
The portsnap servers will continue operating until FreeBSD 13 reaches
its End-of-Life, and portsnap is available from the ports tree as

When not doing tree walks, it is bad for sub-dirs to depend on

In usr.sbin/bsdinstall use SUBDIR_DEPEND_ so tree walking still works.

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.
