The purpose of this change is to reduce the amount of dmesg(8) noise when
VT switching after a panic.

BUILD_BUG_ON() can be used inside functions where the definition to
CTASSERT() (_Static_assert()) seems to not work.
Go back to an old-style CTASSERT() implementation but also add a
variable dclaration to avoid "unsued typedef" errors and dummy-use
the variable to avoid "unusued variable" errors. Given it is all
self-contained in a block and not used outside this should be
optimised away.

Add linux/stringify.h as directly included by drivers. Remove the
definitions from compiler.h and include the new header in places
where the stringify macros are already used without linuxkpi.
I have adjusted the Copyright of the new file according to the commit
originaly adding the macros (99e690772a).

The upcoming in-kernel implementations for LinuxKPI based on work on
iwlwifi (and other wireless drivers) conflicts in a few places with
the drm-kmod graphics work outside the base system.
In order to transition smoothly extract the conflicting bits.
This included "unaligned" accessor functions, sg_pcopy_from_buffer(),
IS_*() macros (to be further restricted in the future), power management
bits (possibly no longer conflicting with DRM), and other minor changes.

list.h includes a number of FreeBSD headers as a workaround for the
LIST_HEAD name collision. To reduce pollution, avoid including list.h
in commonly used headers when it is not explicitly needed.

A set of helper functions have been added to manage the life of the
LinuxKPI task struct. When an external system call or task is invoked,
a check is made to create the task struct by demand. A thread
destructor callback is registered to free the task struct when a
thread exits to avoid memory leaks.
This change lays the ground for emulating the Linux kernel more
closely which is a dependency by the code using the LinuxKPI APIs.
Add new dedicated td_lkpi_task field has been added to struct thread
instead of abusing td_retval[1].

- Move all files related to the LinuxKPI into sys/compat/linuxkpi and
its subfolders.
- Update sys/conf/files and some Makefiles to use new file locations.
- Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn
adds the LinuxKPI to all LINT builds.
- The LinuxKPI can be added to the kernel by setting the
COMPAT_LINUXKPI option. The OFED kernel option no longer builds the
LinuxKPI into the kernel. This was done to keep the build rules for
the LinuxKPI in sys/conf/files simple.
- Extend the LinuxKPI module to include support for USB by moving the
Linux USB compat from usb.ko to linuxkpi.ko.
- Bump the FreeBSD_version.
- A universe kernel build has been done.
