Create ata_param_fixup
Create a common fixup routine to do the canonical fixup of the
ata_param fixup. Call it from both the ATA and the ATA over SCSI
paths.
Go ahead and completely fix the ata_params before calling the veto
function. This breaks nothing that uses it in the tree since
ata_params is ignored in storvsc_ada_probe_veto which is the only
in-tree consumer.

This commit has evolved from the original work to include Capsicum
integration. As part of that, it only opens the host audio devices once
and leaves them open, instead of opening and closing them on each guest
access. Thanks to Peter Grehan and Marcelo Araujo for their help in
bringing the work forward and providing some of the final techncial push.

NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

Summary:
Toolchain follow-up to r349350. LLVM patches will be submitted upstream for
9.0 as well.
The bsd.cpu.mk change is required because GNU ld assumes BSS-PLT if it
cannot determine for certain that it needs Secure-PLT, and some binaries do
not compile in such a way to make it know to use Secure-PLT.

Summary:
PowerPC has two PLT models: BSS-PLT and Secure-PLT. BSS-PLT uses runtime
code generation to generate the PLT stubs. Secure-PLT was introduced with
GCC 4.1 and Binutils 2.17 (base has GCC 4.2.1 and Binutils 2.17), and is a
more secure PLT format, using a read-only linkage table, with the dynamic
linker populating a non-executable index table.
This is the libc, rtld, and kernel support only. The toolchain and build
parts will be updated separately.

Add support for an HTTP "network filesystem" using the UEFI's HTTP
stack.
This also supports HTTPS, but TianoCore EDK2 implementations currently
crash while fetching loader files.
Only IPv4 is supported at the moment. IPv6 support is planned for a
follow-up changeset.
Note that we include some headers from the TianoCore EDK II project in
stand/efi/include/Protocol verbatim, including links to the license instead
of including the full text because that's their preferred way of
communicating it, despite not being normal FreeBSD project practice.

had been done years ago. I did. All this time we've only compiled a LINT
kernel for TARGET_ARCH=arm. Now separate LINT-V5 and LINT-V7 configs are
generated and built.
There are two new files in arm/conf, NOTES.armv5 and NOTES.armv7, containing
some of what used to be in the arm NOTES file. That file now contains only
the bits that are common to v5 and v7.
The makeLINT.mk file now creates the LINT-V5 and LINT-V7 files by concatening
sys/conf/NOTES, arm/conf/NOTES, and arm/conf/NOTES.armv{5,7} in that order.
Port the code to block on turnstile instead of yielding, to lock-less
delayed invalidation. The yield might cause tight loop due to priority
inversion.
Since it is impossible to avoid race between block and wake-up, arm
1-tick callout to wakeup when thread blocks itself.

into existing files for sugid processes.
Despite using real user id pronounces the intent, it actually breaks
suid coredumps, while not making any difference for non-sugid
processes. The reason for the breakage is that non-existent core file
is created with the effective uid (unless weird hacks like SUIDDIR are
configured).
Then, if user enabled kern.sugid_coredump, core dumping should not
overwrite core files owned by effective uid, but we cannot pretend to
use real uid for dumping.

Since SES specs do not define mechanism to map enclosure slots to SATA
disks, AHCI EM code I written many years ago appeared quite useless,
that always bugged me. I was thinking whether it was a good idea, but
if LSI HBAs do that, why I shouldn't?
This change introduces simple non-standard mechanism for the mapping
into both AHCI EM and SES code, that makes AHCI EM on capable controllers
(most of Intel's) a first-class SES citizen, allowing it to report disk
physical path to GEOM, show devices inserted into each enclosure slot in
`sesutil map` and `getencstat`, control locate and fault LEDs for specific
devices with `sesutil locate adaX on` and `sesutil fault adaX on`, etc.
I've successfully tested this on Supermicro X10DRH-i motherboard connected
with sideband cable of its S-SATA Mini-SAS connector to SAS815TQ backplane.
It can indicate with LEDs Locate, Fault and Rebuild/Remap SES statuses for
each disk identical to real SES of Supermicro SAS2 backplanes.
