The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

Some guest allow to configure themself by fw_cfg. E.g. Fedora CoreOs can
be provisioned by adding a JSON file as fw_cfg item.

This will be useful for writing device specific ACPI tables or DSDT

It'll be easier to add new properties to the ACPI device emulation if we
have a struct which holds all device specific properties. In some future
commits the acpi_device_emul struct will be expanded to include some
device specific functions to build ACPI tables.

It is illegal (UB?) to pass a shorter array to a function argument
that takes a fixed-length array. Do a runtime check for names that
are too long via strlen() instead.

Let the user decide if he wants to use bhyve's fwctl or qemu's fwcfg. He
can set the interface by adding a fwcfg option to bootrom:
-l bootrom,<path/to/rom>,fwcfg=bhyve
-l bootrom,<path/to/rom>,fwcfg=qemu

Fwcfg items without a fixed index are reported by the file_dir. They
have an index of 0x20 and above. This helper simplifies the addition of
such fwcfg items. It selects a new free index, assigns it to the fwcfg
items and creates an proper entry in the file_dir.

Qemu defines some common fwcfg items. We don't need to support all of
them. Only a subset needs to be present for fwcfg to work properly.
- signature
The signature is used by the guest to check if qemu's fwcfg is
available or not.
- id
The id is used by the guest to check which features are supported by
the fwcfg implementation of the hypervisor.
- file_dir
The file dir reports all fwcfg items which don't have a fixed index.
These are mostly user defined fwcfg items.

This helper makes it easier to add multiple fwcfg items. You can pass an
index and some data to the helper. The helper adds these information to
the fwcfg emulation so that the guest reads the given data on the
specified index.

qemu's fwcfg and bhyve's fwctl are both used to configure ovmf. qemu's
fwcfg is much more powerfull than bhyve's fwctl. For that reason, add
support for qemu's fwcfg.
