UEFI booting requires an EFI System Partition (ESP). On most storage devices
this will be in a specific partition type. To allow booting from CD/ISO
filesystems, UEFI will look for an ESP in the form of a FAT filesystem image
embedded in the image. Historically FreeBSD has added one of these to its
amd64 ISO images but marked it as simply another i386 boot image. Luckily for
us most UEFI implementations are rather forgiving and work this out for us.
This change adds the ability to mark a boot image as being a UEFI image. It
also modifies our ISO generation to use this marking for the UEFI image we
embed.

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.

Two PRs (152084 & 210187) request allowing the "@" and/or "!"
characters in the passwd file GECOS field. The man page for pw does
not mention that those characters are disallowed, Linux supports those
characters in this field, and the "@" character in particular would be
useful for storing email addresses in that field.

Added the ability to:
* Create virtual interfaces
* Create vlan interfaces
* Get interface fib
* Get interface groups
* Get interface status
* Get nd6 info
* Get media status
* Get additional ifaddr info in a convenient struct
* Get vhids
* Get carp info
* Get lagg and laggport status
* Iterate over all interfaces and ifaddrs
And add more examples, too.
Note that this is a backwards-incompatible change. But that's ok, because it's
a private library.

When attempting to mount a non-directory which exists, return ENOTDIR instead
of ENOENT. If stat() or statfs() failed, don't pass part of the invalid
(struct statfs) to ex_search(). In that same case, preserve the value of "bad"
rather than overwriting with EACCES.

Detect ancient GCC specifically, rather than using target architecture as a
crude heuristic.
Side note: compilers should really ignore -Wno- and -Wno-error= flags they
don't recognize. Seems like modern compilers produce warnings instead of
errors. Though, with -Werror they turn into errors. Clang's error can be
disabled with -Wno-error=unknown-warning-option, but GCC doesn't seem to
have a named method to disable the specific warning.

Specifically reading is done if ffs_sbget() and writing is done
in ffs_sbput(). These functions are exported to libufs via the
sbget() and sbput() functions which then used in the various
filesystem utilities. This work is in preparation for adding
subperblock check hashes.
No functional change intended.
