This patch splits out the ibss code and data from managed (station) mode.
The reason to do this is to better separate the state machines, and have
the code be contained better so it gets easier to determine what exactly
a given change will affect, that in turn makes it easier to understand.
This is quite some churn, especially because I split sdata->u.sta into
sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that
way. I've also shuffled around some code -- null function sending is only
applicable to managed interfaces so put that into that file, some other
functions are needed from various places so put them into util, and also
rearranged the prototypes in ieee80211_i.h accordingly.

This passed my, fairly rigorous, testing:
* associate to AP
* create IBSS
* create different IBSS
* down
* up
* create another IBSS
* associate to AP
without any trouble. Now even with network manager (after Dan kindly
helped me figure out why NM wasn't working in IBSS for me)
It somewhat paves the way to making managed mode entirely optional
should that ever be desired. I didn't do it because that would add
a lot of #ifdefs especially in the wext code.
