Both struct ip and struct udphdr both have an aligment of 2, but the
cast from struct ip to a uint32_t pointer confused GCC 9 into raising
the required alignment to 4 and then raising a
-Waddress-of-packed-member error when casting to struct udphdr.

When a thread exits, _Unwind_ForcedUnwind() is used to walk up stack
frames executing pending cleanups pushed by pthread_cleanup_push().
The cleanups are popped by thread_unwind_stop() which is passed as a
callback function to _Unwind_ForcedUnwind().
LLVM's libunwind uses a different function type for the callback on
32-bit ARM relative to all other platforms. The previous unwind.h
header (as well as the unwind.h from libcxxrt) use the non-ARM type on
all platforms, so this has likely been broken on 32-bit arm since it
switched to using LLVM's libunwind.
For now, just disable stack unwinding on 32-bit arm to unbreak the
build until a proper fix is tested.
It is unused on FreeBSD and complicates some efforts to modify the CTF
format to permit wider type IDs, so remove it. No functional change
intended.

The layout of the structure ends up depending on whether the including
file includes opt_inet.h and opt_inet6.h, so different compilation units
can end up seeing different versions of the structure. Fix this by
unconditionally defining the address fields.
As a side effect, this eliminates some duplication in the kernel's CTF
type graph.

The df command provides a -l option to exclude all non-local file
systems and a -t option with a (positive or negative) list of file
system types to display.
This commit adds support for a combination of -l and -t. If both are
specified, the parameter list of the -t option is applied on top of
the selection of öocal file systems (independently of the order of
the -l and -t options).
E.g., "df -t noprocfs,sysfs -l" will select all local file systems
except those of type procfs and sysfs.

NanoBSD or, more generally, systems with root_rw_mount="NO" are not able
to remove the firstboot_sentinel file, typically /firstboot, because the
logic in /etc/rc is currently inverted.
When checkyesno root_rw_mount tests on a read-only file system, the
return is 1, hence avoiding the option to mount the system read-write.
Restore the ability to remove the firstboot_sentinel file on read-only
mounted file systems.
This change was introduced in 40adda8665, and partially fixed in

Namely:
- main was using two-space indentation
- re-sort local variables
- explicit braces for loop scope
- make flag bit comparison explicit
The first line of this commit message is unfortunately a lie, as it
introduces a minor functional change on non-FreeBSD systems. Namely,
the first branch is now explicitly compared against `0` and the choice
was made to compare it as greater than 0 to avoid issues on other
systems where `argc != 0` on entry isn't guaranteed (negative when
checked there).

This reverts commit 3de96d664a.
Problem is that it is possible to reach the state with ref_count ==
1 for the mapped non-anonymous object. For instance, anonymous posix
shmfd or linux shmfs object could be mapped, and then corresponding
file descriptor closed, dropping the object reference owned by the
shmfd/shmfs file. Then the check in inactive scan assumes that the
object and page are not mapped and frees the page, while they are not.

This was missed in 74d6c131cb where other geom modules were annotated
with MODULE_VERSION. Again, the problem is the same: we can't detect
that geom_md is loaded into the kernel without it.
This was noticed in release builds on the cluster; mdconfig attempts to
load geom_md because it can't detect it in the kernel, but the cluster
config includes md(4) and does not build the kmod. This problem would
have been masked on hosts with the kmod built, as the kmod attempts to
register the g_md module and fails. With this commit, mdconfig would
not even try to load it again.
