If all the pieces of iwlwifi are built into the kernel
then there's no need for it to export its symbols to
other modules, so prevent that.

7000.c was released as GPL only by mistake: it should be
dual licensed - GPL / BSD.
The file that contains the license in the kernel is COPYING
and not LICENSE.GPL.

This is not needed since notif_wait_lock is never accessed
from IRQ.

This code is a library to be used by multiple
opmodes, so move it into the iwlwifi module.

Sometimes, for example when we ask the uCode
for calibration, we wait for the "complete"
response while we also need the results that
are sent in other, interim, notifications.
Currently we handle this by installing an RX
handler globally, but that isn't needed as
this is the only time we want to use these
notifications.
So in order to be able to simplify at least
future code that does the same, extend the
notification wait framework to allow you to
wait for multiple commands and decide based
on the command whether the wait finished.
While at it, also fix a race that can then
become relevant -- if the wait function has
returned true once it shouldn't be called
again, today this can happen due to races
between the triggering and the wakeup.

This will be sharable, but needs to live in the
op_mode as it is dependent on command processing.
Make a library out of the notification wait code.
Since I wrote all of the code originally and only
Intel employees changed it, we can also relicense
it to dual BSD/GPL.
