linuxkpi: move kobject_create to .c file

kobject_create knows the size of struct kobject. Move it to
linux_compat.c so this knowledge is confined to the loadable module and
not the clients.

LinuxKPI: upstream a collection of drm-kmod conflicting changes

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.

Minor LinuxKPI code cleanup:
- Declare some static functions in linux_compat.c instead if inside

- Prefix FreeBSD local functions in the LinuxKPI with "linux_" to
avoid symbol name conflicts in the future and to make debugging
easier.
- Make the "struct kobj_ktype" declaractions constant to shave off a

Finish process of moving the LinuxKPI module into the default kernel build.

- 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.
