If a signal was delivered while the main thread was not in poll(2) and after
check was performed, we could reenter poll and never detect termination. Fix
this with the pipefd trick. (This race was introduced very recently, in
r327482.)

foundation for invoking efibootmgr as part of new-style EFI booting on
x86. On PS3 and PowerNV, which are booted using Linux kexec from petitboot
rather than by loader(8), install the kernel and the rest of /boot to a
FAT partition and set up the appropriate petitboot configuration file
there.
The new bootconfig installer stage can do platform-dependent modifications
more complex than partition layout and installation of boot blocks and can
be used to (as here) set up some special configuration files, run efibootmgr,
or boot0cfg.

one of the directories in the filesystem hierarchy is a FAT mountpoint,
settings its times will fail, which would cause installation to abort.
Instead, make this a best-effort thing.
Handling this error is a hack and a better internal scheme for handling
this should be added to libarchive.
Add missed unistd.h include. Not sure where it was lost; I believe it
compiled before I submitted the change.

o Use open + fstat rather than stat + open to avoid any races for a
file that's static for the life of the system. This will prevent any
problems should someone insert a new device while installing a
kernel in the future.
o Use strlcpy instead of strcpy as a failsafe to knowing that the
strings can't possibly be larger than the buffer due to data
source limits (though in the future these limits might be more
dynamic).
o If we can't find the hints file, return rather than dereference
a NULL pointer.
o Check for lastmod before calling strcmp in case a PNP entry
comes before a module entry. That's not allowed, but within the
realm of crazy things programmers do.
o Free lastmod before exiting search_hints() to avoid a leak.

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.
This squashes the warning gebnerated by GCC 6.x. Since
variables that are now removed had come documentation
value, put relevant bits in comment, so they can be
resurrected from there when actually needed.
After consultation with SPDX experts and their matching guidelines[1],
the licensing doesn't exactly match the BSD-2-Clause. It yet remains to be
determined if they are equivalent or if there is a recognized license that
matches but it is safer to just revert the tags.
Let this also be a reminder that on FreeBSD, SPDX tags are only advisory
and have no legal value (but IANAL).

When building the command to execute for compression, newsyslog was modifying
the generic arguments array instead of its own copy.
Meaning on the second file to compress with the same arguments, the command line
was not the one expected.
Fix it by creating one copy of the arguments per execution and modifying that
copy.
While here, print the command line executed in verbose mode.

We may need to initialize multiple inode blocks before writing a given
inode. makefs(8) was only initializing a single block at a time, so
certain inode allocation patterns could lead to a situation where it
wrote an inode to an uninitialized block. That inode might be clobbered
by a later initialization, resulting in a filesystem image containing
directory entries that point to a seemingly unused inode.
