To allow hardware to work around a broken memory bus where we need to

On arm64 PCI config memory is expected to be mapped with a non-posted
device type. To handle this use the new bus_map_resource support in
arm64 to map memory with the new VM_MEMATTR_DEVICE_NP attribute. This
memory has already been allocated and activated, it just needs to be
mapped.

This fixes an instapanic when restarting wpa_supplicant on my laptop's
iwlwifi device. After this change, iwlwifi enters a nonfunctional
state if wpa_supplicant is restarted, but "service netif restart wlan0"
is enough to get it working again.

When the kernel is built without capability mode support, or when
using an emulator like qemu-user-static that does not translate
system calls, these calls will return a negative number and set
the errno to ENOSYS. However, this error does not indicate a
real programming or runtime error and is generally ignored by
base system applications built with capability mode sandboxing.
Match this behavior by making xz(1) to ignore ENOSYS errors
when calling capability mode system calls too.

netlink(4) and associated features will exist in FreeBSD 14.0 but they
will also exist in 13.2, an older version, from commits such as 02b958b1
and b309249b.
This commit needs merging to stable/13 and releng/13.2.

Many pf tests use identical setup where one jail is a router and
optionally another jail is a server. Add functions to create such jails
for IPv6 and IPv4 and functions to perform tests on such setup.
Add tests using those functions: scrub actions, routing table, tcp
sequence number modulation.

For further use in linux_ioctl_socket add bsd_to_linux_ifflags() which

Split the linux_ioctl_socket() function on two counterparts, where
the linux_ioctl_socket_ifreq() intended to use in a code path which
requires the struct ifreq manipulation, i.e., translating in/out
values of the struct, while the linux_ioctl_socket() function is left
as is, it calls sys_ioctl() without touching in/out values.
Due to structures ifreq, sockaddr difference between FreeBSD and Linux
the linux_ioctl_socket_ifreq() calls kern_ioctl() directly, converting
in and out values to FreeBSD and to Linux accordingly.
Finally, modify the ifname_linux_to_bsd() to return error code, not
an unstable reference to the interface.

For now we are using mixed names to access struct ifreq members, some
of Linux (ifr_name, ifr_ifindex), others of FreeBSD. To avoid conflicts

Enter the net epoch when traversing a list of interfaces. For that
split the ifname_linux_to_bsd() function on two counterparts, where
the ifname_linux_to_ifp() intended to use in epoch, while the
ifname_linux_to_bsd() intended to be a self-contained.
Until the linux_ioctl_coket() function is refactored, the
ifname_linux_to_bsd() temporarily returns interface outside
of the net epoch.

If there is no source filter entry => block if that's SSM ("exclude"
mode per RFC 3678 clause 3). If there is an entry => check its action &
block if the action is "exclude".
It would be nice if the test case in this PR were converted into an ATF
test case, but not blocking on that.
