This fixes connection errors for some initiators not starting CmdSN
from zero.
While there, fix wrong status details reported for couple errors.

The services db is created as a temporary file that is moved over the
existing file after completion. Thus there is no need to immediately
flush all created db records to the temporary file.
This speeds up creation of the services db by a factor of 500 on my
ZFS based /var/db filesytem (from 110 seconds to 0.235 seconds).

This makes runnig f_substr() faster than it was when running under bash,
but both sh and dash are still faster when using the non-bash recipe which
features dynamically unrolled loops.
sysrc(8) supports key+=value and key-=value, but can be told what the
delimiter is by being passed as char1 (e.g., "sysrc key+=",value" to use a
comma as the delimiter instead of space). For convenience, if the first char
is alpha-numeric, it is assumed you wanted whitespace as the delimiter.
However, if you naively (as I just did) execute:
sysrc rc_conf_files+=/etc/rc.conf.other
the result is unexpected.
This commit makes `.' and `/' in-addition to alpha-numeric first-characters
to cause the default of whitespace to be used as the delimiter. This also
means that you can no longer use these as a delimiter.
When using col(1) piped to vim(1) as pager for man(1), the former sequence
of (Qo \ Qc) renders as "" without the space. Replace with (Qo (space) Qc)
which renders properly in more (all?) pagers.
bash lacks the ksh93 optimization that makes sub-shells fast if they do
not alter io. bash 3.1-alpha1 introduced printf -v var_to_set which is not
as fast but is still significantly faster than var_to_set=$( printf ) when
using any version of bash. If we find our interpreter to somehow be bash
by invocation or inclusion, use the feature that provides fastest results.
Enable repeated line compression for lines of any length, instead of only
short lines. AFAICT repeated line compression was limited to short lines as
a RAM optimization, which made sense when karels added it in 1988, but no
longer. The penalty is a paltry 904B of RAM per file logged.

If the bootpool does not start at the first sector of the BSD partition
then zfsldr seeks to the wrong offset inside the ZFS vdev label, and is
unable to find zfsboot, so the system does not boot
If 4k alignment is requested, align the BSD partition in the MBR table,
and align the swap and data pool, but the bootpool must start at sector 1
While here, if 4k alignment is requested, disable MBR CHS alignment, as
this results in not-4k aligned partitions.

The Dell Precision Tower 5810 fails to boot from GPT in Legacy/BIOS mode
without the Active flag in the Protective MBR. Suggest the workaround
during installation.
Since an increasing number of Dell systems exhibit this behavior,
I imagine all Dells past a certain date will do so. I would like
to suggest the workaround for all Dells with a BIOS date of, say,
2014 or later, but I would need to test a variety of systems before
committing such a change.

Relnotes: We should probably suggest using GPT+Active on "recent" Dells.
