Merge support for SATA NCQ (Native Command Queueing) from jdolecek-ncq branch

ATA subsystem was changed to support several outstanding commands, and use
NCQ xfers if supported by both the controller and the disk, including NCQ
error recovery. Set NCQ high priority for BPRIO_TIMECRITICAL xfers
if supported. Added FUA support.

Done some work towards MP-safe, all ATA code tsleep()/wakeup() replaced
by condvars, and switched most code from spl* to mutexes (separate
wd(4) and ata channel lock).

Introduced new option WD_CHAOS_MONKEY to facilitate testing of error
handling, fixed several uncovered issues. Also fixed several problems
with kernel dump to wd(4) disk.

Tested with ahcisata(4), mvsata(4), siisata(4), piixide(4) on amd64,
with and without port multiplier, both disk and ATAPI devices; other
drivers and archs mechanically adjusted and compile-tested. NCQ is
supported for ahcisata(4) and siisata(4) for any controller, for
mvsata(4) only Gen IIe ones for now. Also enabled ATAPI support in
mvsata(4).

Thanks to Matt Thomas for initial ATA infrastructure patch, and
Jonathan A.Kollasch for siisata(4) NCQ changes and general testing.

Also fixes PR kern/43169 (wd(4)); and PR kern/11811, PR kern/47041,
PR kern/51979 (kernel dump)

This is what was posted here:

with minor cleanup, and the global switch replaced by a mount option.

Add some more elements to struct ataparams.

These mostly concern the new Long Physical Sectors
and Long Logical Sectors feature sets.

Information from a draft of ACS-2, with some additional
in-between members and bits being borrowed from OpenBSD.

There's lots more in ACS-2 we could add, but for the most
part it would be superfluous.

XXX: Some elements marked as reserved no longer are,
and some elements we still reference are now obsolete.

Correct an error in previous commit.

Convert to C99 types. Make whitespace more consistent.

Provide atacmd_to48() in case of #if defined(_STANDALONE) too
because standalone wdc driver in cobalt bootloader requires it
for LBA48 support.

Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen
for the booring work !

Improved SATA support, from Jonathan A. Kollasch in PR bin/36772:
* use full 5-bit command queue depth that SATA supports
* decode SATA bits

__unused removal on arguments; approved by core.

A little effort against kernel bloat....
Exclude ATA DMA support if no ATA DMA capable drivers are compiled in.

Typo: WCDD_SECURITY_FREEZE -> WDCC_SECURITY_FREEZE

Noticed by Sergey Svishchev.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

add definition for "security freeze"
