linuxkpi: refcount: Use atomic_t directly

Simply use a typedef for refcount_t on atomic_t, this allow us
to use a nativ type and also changing struct kref to directly use
a refcount_t like Linux.

kref: switch internal type to atomic_t and bring back const to kref_read

This unbreak drm-kmod build.

the const is part of Linux API

Unfortunately drm-kmod uses hand-rolled refcount* calls on a kref
object. For now go the easy route of keeping it operational by casting
stuff internally.

The general goal here is to make FreeBSD refcount API use an opaque
type, hence the ongoing removal of hand-rolled accesses.

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.
