fa56dddd67 mac80211: ieee80211_ibss_commit() cleanup
Don't call ieee80211_sta_find_ibss() directly, like it's done in STA
mode, so that the commit() call is more harmless respectively has
less site-effects.

707c1b4e68 mac80211: Update IBSS beacon timestamp properly
In IBSS mode, the beacon timestamp has to be filled with the
BSS's timestamp when joining, and set to zero when creating
a new BSS.

4a332a385a mac80211: Give it some time to do the TSF sync
Give slow hardware some time to do the TSF sync, to not run into an
IBSS merging endless loop in some rarely situations.

34e8f08231 mac80211: Don't merge with the same BSSID
It was not a good idea to do a TSF reset on strange IBSS merges to the same BSSID. For example it will break the TSF sync of ath9k completely and it is unnecessary as all hardware I have tested do a TSF sync to a higher value automatically and IBSS merges are only done to higher TSF values. It only need a TSF reset to accept a lower value, when the IBSS network is changed manually.

79f6440c52 mac80211: Introduce a generic commit() to apply changes
This patch introduces a generic commit() function which initiate a
new network joining process. It should be called after some interface
config changes, so that the changes get applied more cleanly. Currently
set_ssid() and set_bssid() call it. Others can be added in future
patches.

In version 1 the header files was forgotten, sorry.

469002983f mac80211: split IBSS/managed code
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.
