linuxkpi: Introduce a properly typed jiffies

Now that we have a long-sized tick counter, we can migrate to using
properly typed timeout parameters in various bits of the LinuxKPI. This
fixes a subtle incompatibility that is otherwise difficult to paper over
and leads to bugs when ticks values are sign-extended.

- Introduce a "jiffies" symbol in subr_ticks.S, declared only in the
LinuxKPI as an unsigned long.
- Remove all references to "ticks" from the LinuxKPI.
- Convert interfaces to match Linux's type signatures where it makes
sense.

Revert: LinuxKPI: switch jiffies and timer->expire to unsigned long

There are possible problems when jiffies (ticks) which still are int
wrap around. Also given this did not touch every single place some
checks may be broken now.

LinuxKPI: switch jiffies and timer->expire to unsigned long

It seems these functions work with unsigned long and not int in Linux.
Start simply replacing the int where I came across it while debugging
a wireless driver timer modification. Also sprinkle in some "const".

linuxkpi: Fix mod_timer and del_timer_sync

mod_timer is supposed to return 1 if the modified timer was pending, which
is exactly what callout_reset does so return the value after checking
that it's a correct one in case the api change.
del_timer_sync returns int so add a function and handle that.

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.
