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
1ce07411fa.

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.

The ESXi NFSv4.1 client bogusly sends the wrong value
for the csa_sequence argument for a Create_session operation.
RFC8881 requires this value to be the same as the sequence
reply from the ExchangeID operation most recently done for
the client ID.
Without this patch, the server replies NFSERR_STALECLIENTID,
which is the correct response for an NFSv4.0 SetClientIDConfirm
but is not the correct error for NFSv4.1/4.2, which is
specified as NFSERR_SEQMISORDERED in RFC8881.
This patch fixes this.
This change does not fix the issue reported in the PR, where
the ESXi client loops, attempting ExchangeID/Create_session

The NVMe 1.4 spec simply says that Model and Serial numbers are
ASCII strings. Unlike SCSI, it doesn't prohibit non-printable
characters or say that the strings should be padded with spaces.
Since 2014, we have had cam_strvis_sbuf(), which gives additional
options for handling non-ASCII characters. That behavior hasn't
been available for non-sbuf consumers, so users of cam_strvis()
were left with having octal ASCII codes inserted.
So, to avoid having garbage or octal chracters in the strings, use
cam_strvis_sbuf() to create a new function, cam_strvis_flag(), and
re-implement cam_strvis() using cam_strvis_flag().
Now, for the NVMe drives, we can use cam_strvis_flag with the
CAM_STRVIS_FLAG_NONASCII_SPC flag. This transforms non-printable
characters into spaces.
sys/cam/cam.c:
Add a new function, cam_strvis_flag(), that creates an sbuf
on the stack with the user's destination buffer, and calls
cam_strvis_sbuf() with the given flag argument.
Re-implement cam_strvis() to call cam_strvis_flag with the
CAM_STRVIS_FLAG_NONASCII_ESC argument. This should be the
equivalent of the old cam_strvis() function, except for the
overhead of creating the sbuf and calling sbuf_putc/printf.
sys/cam/cam.h:
Declaration for cam_strvis_flag.
sys/cam/nvme/nvme_all.c:
In nvme_print_ident, use the NONASCII_SPC flag with
cam_strvis_flag().
sys/cam/nvme/nvme_da.c:
In ndaregister(), use cam_strvis_flag() with the
NONASCII_SPC flag for the disk description and serial
number we report to GEOM.

In nvme_probe_done(), use cam_strvis_flag with the

The optimization of sysctlbyname() in commit d05b53e0ba had the
side-effect of not going through the fix-up for the user.* variables
in the previously called sysctl() function.
This lead to 0 or an empty strings being returned by sysctlbyname()
for all user.* variables.
An alternate implementation would store the user variables in the
kernel during system start-up. That would allow to remove the fix-up
code in the C library that is currently required to provide the actual
values.
This update restores the previous code path for the user.* variables
and keeps the performance optimization intact for all other variables.

In GNU ld and ld.lld, -dc is used with -r to allocate space to COMMON
symbols. It is presumably to work around legacy code which cannot
handle COMMON symbols in relocatable output. ld.lld may remove -dc or
make it a no-op for the 15.0.0 release.
As of 7420b323a0 crunch/crunchide does not require -dc, as the symbol
hiding technique no longer relied on making symbols local.
In addition -fno-common is now the default in Clang and GCC, so -dc
serves no purpose as the compiler does not generate COMMON symbols
anyway.
