vmd(4): Major driver refactoring

- Re-implement pcib interface to use standard pci bus driver on top of
vmd(4) instead of custom one.
- Re-implement memory/bus resource allocation to properly handle even
complicated configurations.
- Re-implement interrupt handling to evenly distribute children's MSI/
MSI-X interrupts between available vmd(4) MSI-X vectors and setup them
to be handled by standard OS mechanisms with minimal overhead, except
sharing when unavoidable.

Successfully tested on Dell XPS 13 laptop with Core i7-1185G7 CPU (VMD
device ID 0x9a0b) and single NVMe SSD, dual-booting with Windows 10.

Successfully tested on Supermicro X11DPI-NT motherboard with Xeon(R)
Gold 6242R CPUs (VMD device ID 0x201d), simultaneously handling NVMe
SSD on one PCIe port and PLX bridge with 3 NVMe and 1 AHCI SSDs on
another. Handles SSD hot-plug (except Optane 905p for some reason,
which are not detected until manual bus rescan) and enabled IOMMU
(directly connected SSDs work, but ones connected to the PLX fail
without errors from IOMMU).

This controller supports 2.5G/1G/100MB/10MB speeds, and allows

The driver was derived from code contributed by Intel, and modified
by Netgate to fit into the iflib framework.

Thanks to Mike Karels for testing and feedback on the driver.

Introduce DXR as an IPv4 longest prefix matching / FIB module

DXR maintains compressed lookup structures with a trivial search
procedure. A two-stage trie is indexed by the more significant bits of
the search key (IPv4 address), while the remaining bits are used for
finding the next hop in a sorted array. The tradeoff between memory
footprint and search speed depends on the split between the trie and
the remaining binary search. The default of 20 bits of the key being
used for trie indexing yields good performance (see below) with
footprints of around 2.5 Bytes per prefix with current BGP snapshots.

Rebuilding lookup structures takes some time, which is compensated for by
batching several RIB change requests into a single FIB update, i.e. FIB
synchronization with the RIB may be delayed for a fraction of a second.
RIB to FIB synchronization, next-hop table housekeeping, and lockless
lookup capability is provided by the FIB_ALGO infrastructure.

DXR works well on modern CPUs with several MBytes of caches, especially
in VMs, where is outperforms other currently available IPv4 FIB
algorithms by a large margin.

Build VirtIO modules on all architectures

Currently only amd64, i386 and powerpc build VirtIO modules, yet all other
architectures have at least one kernel configuration that includes the

statically compile into the kernel. Instead, enable the build everywhere so all
architectures have the full set of device drivers available.

Add driver for Synopsys Designware Watchdog timer.

This driver supports some arm and arm64 boards equipped with
"snps,dw-wdt"-compatible watchdog device.
Tested on RK3399-based board (RockPro64).
Once started watchdog device cannot be stopped.
Interrupt handler has mode to kick watchdog even when software does not do it
properly.
This can be controlled via sysctl: dev.dwwdt.prevent_restart.
Also - driver handles system shutdown and prevents from restart when system
is asked to reboot.

Bring DPDK route lookups to FreeBSD.

This change introduces loadable fib lookup modules based on
DPDK rte_lpm lib targeted for high-speed lookups in large-scale tables.
It is based on the lookup framework described in D27401.

IPv4 module is called dpdk_lpm4. It wraps around rte_lpm [1] library.
This library implements variation of DIR24-8 [2] lookup algorithm.
Module provide lockless route lookups and in-place incremental updates,
allowing for good RIB performance.

IPv6 module is called dpdk_lpm6. It wraps around rte_lpm6 [3] library.
Implementation can be seen as multi-bit trie where the stride or number of bits
inspected on each level varies from level to level.
It can vary from 1 to 14 memory accesses, with 5 being the average value
for the lengths that are most commonly used in IPv6.
Module provide lockless route lookups for global unicast addresses
and in-place incremental updates, allowing for good RIB performance.

Implementation details:
* wrapper code lives in `sys/contrib/dpdk_rte_lpm/dpdk_lpm[6].c`.
* rte_lpm[6] implementation contains both RIB and FIB code.
. RIB ("rule_") code, backed by array of hash tables part has been commented out,
as base radix already provides all the necessary primitives.
* link-local lookups are currently implemented as base radix lookup.
This part should be converted to something like read-only radix trie.

Usage detail:
Compile kernel with option FIB_ALGO and load dpdk_lpm4/dpdk_lpm6
module at any time. They will be picked up automatically when
amount of routes raises to several thousand.
