The feature enables us to pass through physical PCIe devices to FreeBSD VM
running on Hyper-V (Windows Server 2016) to get near-native performance with
low CPU utilization.

The patch implements a PCI bridge driver to support the feature:

1) The pcib driver talks to the host to discover device(s) and presents
the device(s) to FreeBSD's pci driver via PCI configuration space (note:
to access the configuration space, we don't use the standard I/O port
0xCF8/CFC method; instead, we use an MMIO-based method supplied by Hyper-V,
which is very similar to the 0xCF8/CFC method).

2) The pcib driver allocates resources for the device(s) and initialize
the related BARs, when the device driver's attach method is invoked;

3) The pcib driver talks to the host to create MSI/MSI-X interrupt
remapping between the guest and the host;

4) The pcib driver supports device hot add/remove.

vcpu_id is host's representation of guest CPU.
We get the mapping between vcpu_id and FreeBSD kernel's cpu id when VMBus
driver is loaded. Later, when a driver, like the coming pcib driver, talks
to the host and needs to refer to a guest CPU, the driver must use the
vcpu_id.

Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages.  This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.

Core kernel is always compiled with -msoft-float on all of our platforms,
make sure we follow the suit with trampoline as well.

Rather than printing a warning for every time we receive a fileid > 2^32
from the NFS server, count warnings and print at most one of each warning
type per minute, e.g.,

Nov 15 05:17:34 ip-172-30-1-221 kernel: NFSv4 fileid > 32bits (24730 occurrences)
Nov 15 05:17:56 ip-172-30-1-221 kernel: NFSv4 mounted on fileid > 32bits (178 occurrences)
Nov 15 05:18:53 ip-172-30-1-221 kernel: NFSv4 fileid > 32bits (7582 occurrences)
Nov 15 05:18:58 ip-172-30-1-221 kernel: NFSv4 mounted on fileid > 32bits (23 occurrences)

A buildworld with an NFS mounted /usr/obj can otherwise result in
hundreds of thousands of lines being printed, which seems unnecessarily
verbose.

When ino_t becomes a 64-bit type, these printfs will no longer be needed
(and the problems associated with truncating 64-bit fileids to generate
32-bit inode numbers will also go away).
