pmc: Add new sub-command structured "pmc" utility

This will manage pmc functionality with a more
manageable structure of subcommands rather than the
gradually accreted spaghetti logic of overlapping flags
that exists in pmcstat.

This is intended to ultimately have all the same functionality
as pmcannotate+pmccontrol+pmcstat. Currently it just has
"stat" and "system-stat" - counters for the process itself and counters
for the system as a whole respectively (i.e. system-stat includes kernel
threads). Note that the rusage results (page faults/context switches/
user/sys) for stat-system will not account for the system as a whole -
only for the child process specified on the command line.

Implementing stat was suggested by mjg@ and the output is based on that
from Linux's "perf stat".

Add kernel and userspace code to dump the firmware state of supported
ConnectX-4/5 devices in mlx5core.

The dump is obtained by reading a predefined register map from the
non-destructive crspace, accessible by the vendor-specific PCIe
capability (VSC). The dump is stored in preallocated kernel memory and
managed by the mlx5tool(8), which communicates with the driver using a
character device node.

The utility allows to store the dump in format
<address> <value>
into a file, to reset the dump content, and to manually initiate the
dump.

A call to mlx5_fwdump() should be added at the places where a dump
must be fetched automatically. The most likely place is right before a
firmware reset request.

Match unattached devices on the system to potential kernel modules.

devmatch(8) matchs up devices in the system device tree with drivers
that may match them. For each unattached device in the system, it
tries to find matching PNP info in the linker hints and prints modules
to load to claim the devices.

In --unbound mode, devmatch can look for drivers that have attached to
devices in the device tree and have plug and play information, but for
which no PNP info exists. This helps find drivers that haven't been
converted yet that are in use on this system.

In addition, the ability to dump out linker.hints is provided.

Future commits will add hooks to devd.conf and rc.d to fully automate
using this information.

efibootmgr manages the UEFI BootXXXX variables that implement the UEFI
Boot Manager protocol defined in the UEFI standards. It is modeled
after the Linux program of the same name with a mostly compatible set
of command line options. Since there's a fair amount of OS specifioc
code due to differeing names and methods of doing things, the
compatibility isn't 100%.

Basic functionality is implemented, though the more advanced next boot
functionality that's been defined elsewhere is unimplemented.
