/etc/rc.d/securelevel is supposed to run /etc/rc.d/sysctl lastload
late at boot time to apply /etc/sysctl.conf settings that fail
to apply early. However, this does not work in default configuration
because of kern_securelevel_enable="NO" by default.
Add new script /etc/rc.d/sysctl lastload that starts unconditionally.

Currently ipfw has multiple components that are not parts
of GENERIC kernel like dummynet etc. They can bring in important
sysctls if enabled with rc.conf(5) and loaded with ipfw startup script
by means of "required_modules" after initial consult
with /etc/sysctl.conf at boot time. Here is an example of one
increasing limit for dummynet hold queues that defaults to 100:
net.inet.ip.dummynet.pipe_slot_limit=1000
This makes it possible to use ipfw/dummynet rules such as:
ipfw pipe 1 config bw 50Mbit/s queue 1000
Such rule is rejected unless above sysctl is applied.
Another example is a group of net.inet.ip.alias.* sysctls
created after libalias.ko loaded as dependency of ipfw_nat.
This is not a problem if corresponding code compiled in custom kernel
so sysctls exist when sysctl.conf is read early or kernel modules
loaded with a loader. This change makes it work also for GENERIC
and modules loaded by means of rc.conf(5) settings.

rtld preserves its current error message around calls to user init/fini
lists, to not override original error with potential secondary errors
caused by user code recursing into rtld. After 4d9128da54,
the preservation of the string itself is not enough, the 'seen'
indicator must be preserved as well. Otherwise, since new code does not
clear string (it cannot), call to _rtld_error() from errmsg_restore()
revived whatever message was consumed last.
Change errmsg_save() to return structure recording both 'seen' indicator
and the message, if any.

It was unused since 405c3050f1, which removed iBCS support.
This also moves the 'linux' rc script slightly earlier, which
might help in some setups. The original version of this patch
moved it even more, before 'mountcritlocal', which would fixe
mount(8) errors due to missing /dev/shm in setups with entries
for /path/to/chroot/dev/shm without the "late" flag; however,
in the end 'kldxref' turned out to depend on 'mountcritlocal'
anyway.

Right now, libthr does not initialize RtldLockInfo.rtli_version when calling
_rtld_thread_init(), which makes versioning the interface troublesome.
Add a workaround: if the calling object of _rtld_thread_init() exports
the "_pli_rtli_version" symbol, then consider rtli_version initialized.
Otherwise, forcibly set it to RTLI_VERSION_ONE, currently defined as
RTLI_VERSION.
Export "_pli_rtli_version" from libthr and properly initialize rtli_version.

If the root file system is composed from multiple devices, wait for
devices to be ready before running zpool and dumpon rc scripts.
An example of this is if the bulk of the root file system exists on a
fast device (e.g. NVMe) but the /var directory comes from a ZFS dataset
on a slower device (e.g. SATA). In this case, it is possible that the
zpool import may run before the slower device has finished being probed,
leaving the system in an intermediate state.
Fix is to add root_hold_wait to the zpool and dumpon (which has a
similar issue) rc scripts.

This may be used to optimize a loading process - in the case when
we already have a file descriptor to the library; we don't have
to look into multiple PATH to find it.
It may also be used in capability mode to load a single additional
library without the need to open a directory that contains it.
The last use of this functionality t may be a race-free method

Daniel reported that NFSv4 mounts were not working despite having
set "nfsv4_server_enable=YES" in /etc/rc.conf. Mountd was logging a
message that there was no /etc/exports file.
He noted that creating a /etc/exports file with a "V4:" line in it
was needed make NFSv4 mounts work.
At least one "V4:" line in one of the exports(5) file(s) is needed to
make NFSv4 mounts work. This patch fixes mountd.c so that it logs a
message indicting that there is no "V4:" line in any exports(5)
file when NFSv4 mounts are enabled.
To avoid this message being generated erroneously, /etc/rc.d/mountd
is updated to make sure vfs.nfsd.server_max_nfsvers is properly set
before mountd(8) is started.

77e1ccbee3 introduced a bug whereby
rc scripts in etc/rc.d and $local_startup failed to parse output
from called commands because IFS was set to " " instead of the
default " \t\n". This caused parsing of output that contains any
whitespace character, such as tabs and newlines, not matching just a
space to fail.

77e1ccbee3 introduced parallel execution
of rc. It separated groups with line feeds (\n) and elements within
groups using spaces. This is a natural separation due to rcorder
using spaces and lines to separate elements within groups with groups
of services separated by line feeds.
77e1ccbee3 parses the output from rcorder
by setting $IFS. However it failed to reset $IFS to default ' \t\n'
prior to calling find_local_scripts_new(), causing find_local_scripts_new()
to fail parsing $local_startup for site-specific local rc scripts, i.e.
${LOCALBASE}/etc/rc.d. This caused daemons from ports and packages such
as postfix, dovecot, nut, and others in ${LOCALBASE} not to be started.
