Fetch FreeBSD-LoaderEnv UEFI enviornment variable. If set, read in
loader environment variables from it. Otherwise read in
/efi/freebsd/loader.env. Both are read relative to the device
loader.efi loaded from (they aren't full UEFI device paths)
Next fetch FreeBSD-NextLoaderEnv UEFI environment variable. If
present, read the file it points to in as above and delete the UEFI
environment variable so it only happens once.
This lets one set environment variables in the bootloader.
Unfortunately, we don't have all the mechanisms in place to parse the
file, nor do we have the magic pattern matching in place that
loader.conf has. Variables are of the form foo=bar. No quotes are
supported, so spaces aren't allowed, for example. Also, variables like
foo_load=yes are intercepted when we parse the loader.conf file and
things are done based on that. Since those aren't done here, variables
that cause an action to happen won't work.

It was reported that without #ifdef INET6 around the declaration of "nbuf",

stdin is closed and ncat initiates a graceful shutdown of the SCTP
association. This is not expected by the client. Therefore, the
ncat-based discard server is replaced by a perl-based one.
In addition, to remove the dependency from ncat, which needs to be
installed via the nmap port, also the code testing for a free SCTP port
is changed to use the perl-based client.
Finally, remove some debug output from the report generated.

Add support to enable, save, and restore the following facilities:
* Target Address Register (bctar) -- seemingly just another register to
branch to.
* Event-based branching -- an interrupt-like userspace event handler
subsystem.
* Load-monitored facility -- A facility that allows monitoring a range of
physical memory, and triggering an event on access. Targeted to garbage
collection software features.
The Data Stream Control Register (DSCR) is privileged on POWER7, but
unprivileged (different register) on POWER8 and later. However, it's now
guarded by a new register, the Facility Status and Control Register, instead of
the MSR like other pre-existing facilities (FPU, Altivec). The FSCR must be
managed explicitly, since it's effectively an extension of the MSR.

Since the non-volatile registers are restored at the end of cpu_switchin (of
the new thread) they're free for us to use for our own purposes. Load the
PCB_FLAGS into a non-volatile register so it's preserved across the C
function calls that manage FPU and altivec state. This removes 4 loads from
each file. Might be a trivial performance improvement (~12 clock cycles per
context switch).

Add map-vdisk and unmap-vdisk commands to create virtual disk interface on top of file. This will allow to use disk image from file system to load and start the kernel.
By mapping file, we create vdiskX device, the device will be listed by lsdev [-v] and can be accessed directly as ls vdisk0p1:/path or can be used as value for currdev variable.
vdisk strategy function does not use bcache as we have bcache used with backing file. vdisk can be unmapped when all consumers have closed the open files.
In first iteration we do not support the zfs images because zfs pools do keep the device open (there is no "zpool export" mechanism). Adding zfs support is relatively simple, we just need to run zfs disk probe after mapping is done.

When the CPU Topology was added to bhyve in r332298 the SMBIOS table was

By default, cores are now assigned to queues in a sequential
manner rather than all NICs starting at the first core. On a four-core
system with two NICs each using two queue pairs, the nic:queue -> core
mapping has changed from this:
0:0 -> 0, 0:1 -> 1
1:0 -> 0, 1:1 -> 1
To this:
0:0 -> 0, 0:1 -> 1
1:0 -> 2, 1:1 -> 3
Additionally, a device can now be configured to use separate cores for TX
and RX queues.
Two new tunables have been added, dev.X.Y.iflib.separate_txrx and
dev.X.Y.iflib.core_offset. If core_offset is set, the NIC is not part
of the auto-assigned sequence.
