Allow udp tunnel functions to indicate they have not taken ownership of
the packet, and that normal UDP processing should continue.
This is especially useful for scenarios where the kernel has taken
ownership of a socket that was originally created by userspace. It
allows the tunnel function to pass through certain packets for userspace
processing.
The primary user of this is if_ovpn, when it receives messages from
unknown peers (which might be a new client).

When FreeBSD is running as dom0 (initial domain) on a Xen system it
has access to the native ACPI tables and is the OSPM. However the
hypervisor is the entity in charge of the CPU idle and frequency
states, and in order to perform this duty it requires information
found the ACPI dynamic tables that can only be parsed by the OSPM.
Introduce a new Xen specific ACPI driver to fetch the Processor
related information and upload it to Xen. Note that this driver needs
to take precedence over the generic ACPI CPU driver when running as
dom0, so downgrade the probe score of the native driver to
BUS_PROBE_DEFAULT in order for the Xen specific driver to use
BUS_PROBE_SPECIFIC.
Tested on an Intel NUC to successfully parse and upload both the Cx and
Px states to Xen.

Little refactoring to complete the conversion to bsddialog(3),
not functional changes:
* Delete: remaining code for autosizing using BSDDIALOG_AUTOSIZE.
* Add: constants to delete magical numbers and to avoid unclear

* Delete: redundant 'conf.button.default_cancel=false', performed by
bsddialog_initconf().
* Add: a new function message_zoneinfo_file() to merge features.

X_ip_mrouter_done() was calling the interface ioctl routines via
if_allmulti() while holding a write lock. However, some interface
ioctl routines, including em/iflib and tap, use sxlocks, which are
not permitted while holding a non-sleepable lock, and this elicits
a warning from WITNESS. Fix the locking issue by recording the
affected interface pointers in a malloc'ed array, and call
if_allmulti() on each after dropping the rwlock.

Inactive Ethernet rules get cleaned by a net_epoch callback. This
callback may still be pending when we try to start a new (pf rules)
transaction, causing it to fail.
This is especially likely to occur in scripted scenarios, such as the
regression tests.
Drain the epoch callbacks before starting a new transaction, ensuring
we've had the opportunity to clean up the inactive rules.

For IPv4 use dst pointer as destination address in fib4_lookup().
It keeps destination address from IPv4 header and can be changed
when PACKET_TAG_IPFORWARD tag was set by packet filter.
For IPv6 override destination address with address from dst_sa.sin6_addr,
that was set from PACKET_TAG_IPFORWARD tag.

Matching for DSCP codes has used incorrect bits. Use IPV6_DSCP()
macro for matching opcodes to fix this. Also this leads to always
use value from a mbuf instead of cached value.
Previously different opcodes have used both cached in f_id value
and stored in the mbuf, and it did not always work after setdscp
action, since cached value was not updated.
Update IPv6 flowid value cached in the f_id.flow_id6 when we do
modification of DSCP value in O_SETDSCP opcode, it may be used by
external modules.
Also added logging support for O_SETDSCP opcode.

The correct OID format for CTLTYPE_U64 is `QU` (`uquad_t`), not `A`
(text expressed via `char *`).
This issue was noticed while doing an sysctl tree walk using a
sysctl(9) consumer that relies on the OID format to intuit what the
type should be for a given sysctl.

The "void *stuff" (also called fstuff and dstuff) argument
was used by the Mac OSX port. For FreeBSD, this argument
is always NULL, so remove it to clean up the code.
This commit gets rid of "stuff" for nfscl_request().
Future commits will do the same for other functions.
On some hardware the EFI system table is not in memory mapped in the
