Wake On LAN packets sent by wake(8) via BPF are lost if txcsum is
enabled. These fall into the "other protocol" case where gen_parse_tx
did nothing. Add code to shift up to gen_tx_hdr_min bytes of the
packet along with the Ethernet header in this case.
Maintain a pointer to an element in the domain map that is left of any
sufficiently large free gap in the tree and start the search for free
space there, rather than at the root of the tree. On find_space, move
that pointer to the leftmost leaf in the subtree of nodes with
free_down greater than or equal to the minimum allocation size before
starting the search for space from that pointer. On removal of a node
with address less than that pointer, update that pointer to point to
the predecessor or successor of the removed node.
In experiments with netperf streaming, this reduces by about 40% the
number of map entries examined in first-fit allocation.

744bfb2131 ("Import the WireGuard driver from zx2c4.com") re-imported
the WireGuard driver with the intention that wg(8) will be used to
manage WireGuard interfaces, as on other platforms, now that wg(8) has
been dual-licensed MIT specifically to allow our use in base (thanks!).
This is a copy of wireguard-tools/src, with files that we don't need
.gitignore'd out to make it more clear that we're only building files
that are either MIT or dual-licensed MIT. We may go with a different
structure later (e.g., if we end up needing to include outside of src/),
but an upstream restructure seems unlikely in the foreseeable future.
Some architectures will pretty-print a system call trap in the
backtrace. Rather than printing the symbol, use the syscallname()
function to pull the string from the sv_syscallnames array corresponding
to the process. This simplifies the function somewhat.
Mostly, this will result in dropping the "sys" prefix, e.g. "sys_exit"
will now be printed simply as "exit".
Make two minor tweaks to the function signature: use a u_int for the
syscall number since this is a more correct type (see the 'code' member
of struct syscall_args), and make the thread pointer the first argument.
The latter is more natural and conventional.

The change extends vmimage.subr to handle a new parameter, VMFS, which
should be equal to either "ufs" or "zfs". When it is set to ZFS, we use
makefs to create a bootable pool populated using the same dataset layout
as bsdinstall and "poudriere image" use. The pool can be grown using
the growfs rc.d script, just as in UFS images.
This will make it easy to provide VM and cloud images with ZFS as the
root filesystem. So far I did not do extensive testing of cloud images;
I merely verified that creation of ZFS-based AWS AMIs works and allows
me to create amd64 and arm64 EC2 instances with ZFS as the root
filesystem.

This code was originally written under the assumption that the ISA
string would only contain single-letter extensions. The RISC-V
specification has extended its description of the format quite a bit,
allowing for much longer ISA strings containing multi-letter extension
names.
Newer versions of QEMU (7.1.0) will append to the riscv,isa property
indicating the presence of multi-letter standard extensions such as
Zfencei. This triggers a KASSERT about the expected length of the
string, preventing boot.
Increase the size of the isa array significantly, and teach the code
to parse (skip over) multi-letter extensions, and optional extension
version numbers. We currently ignore them completely, but this will
change in the future as we start supporting supervisor-level extensions.

Add hostfs for the Linux environment. We can't use the userboot one
that's kinda similar because the Linux system calls we have in kboot are
not quite POSIX compliant (Linux takes care of providing the POSIX

area.
