62bae5d421 The LinuxKPI atomics do not have acquire nor release semantics unless
specified. Fix code to use READ_ONCE() and WRITE_ONCE() where appropriate.

29cbb3bef2 LinuxKPI atomic fixes:
- Fix implementation of atomic_add_unless(). The atomic_cmpset_int()
  function returns a boolean and not the previous value of the atomic
  variable.
- The atomic counters should be signed according to Linux.
- Some minor cosmetics and styling while at it.

8d59ecb214 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.
