Use CAM_DEV_NOT_THERE instead of CAM_SEL_TIMEOUT to report nonexistent
LUNs for the virtual processor device. This removes lots of CAM warnings,
and follows similar recent changes to tws(4) and twa(4) drivers.
Also fix case where CAM_REQ_CMP was getting OR'd with CAM_DEV_NOT_THERE
in the nonexistent LUN case, resulting in different CAM status (CAM_UA_TERMIO)
getting reported to CAM. This issue existing previously, but was more subtle
because it changed CAM_SEL_TIMEOUT to CAM_CMD_TIMEOUT.

Fix an old bug in devd, where it uses std::sort() to sort the various
lists it reads from its configuration files on the priority field.
Because some items in the lists have the same priority, and std::sort()
is not stable, the exact order in which the items are enumerated does
not have to correspond to the order they appear in the configuration
files.
Apparently this was never noticed with libstdc++, but with libc++ it
could cause the "uhid" entry from /etc/devd/usb.conf to be used instead
of the "ums" entry (which is earlier in the file). This caused the
problem described in the PR: the USB mouse module was never loaded, and
the other actions (such as starting moused) were not executed.
To fix the problem, make devd use std:stable_sort() instead.

Note that the manual page of less(1) says:
Note that a preprocessor cannot output an empty file, since that
is interpreted as meaning there is no replacement, and the origi-
nal file is used. To avoid this, if LESSOPEN starts with two ver-
tical bars, the exit status of the script becomes meaningful. If
the exit status is zero, the output is considered to be replace-
ment text, even if it empty. If the exit status is nonzero, any
output is ignored and the original file is used. For compatibil-
ity with previous versions of less, if LESSOPEN starts with only
one vertical bar, the exit status of the preprocessor is ignored.
Use two pipe symbols for zless, so that zless'ing a compressed empty
file will give output rather than being interpreted as its compressed
form, which is typically a binary.

Don't call bus_dmamap_load in CAM_DIR_NONE case, since there is nothing

Functionally, it works OK (at least on x86) to call bus_dmamap_load with
a NULL data pointer and zero length, so this is primarily for correctness
and consistency with other drivers.
While here, remove check in isci_io_request_construct for nseg==0.
Previously, bus_dmamap_load would pass nseg==1, even for case where
buffer is NULL and length = 0, which allowed CAM_DIR_NONE CCBs
to get processed. This check is not correct though, and needed to be
removed both for the changes elsewhere in this patch, as well as jeff's

For C1 and C2 states use cpu_ticks() to measure sleep time instead of much

less important there as wake up latency is high any way.
For C1 and C2 states do not check/clear bus mastering activity status, as
it is important only for C3. As side effect it can make CPU enter C2 instead
of C3 if last BM activity was two sleeps back (unlike one before), but
that may be even good because of collecting more statistics. Premature BM
wakeup from C3, entered because of overestimation, can easily be worse then
entering C2 from both performance and power consumption points of view.
