Jouni Malinen de88430311 nl80211: Fix del_ifidx() with mixed parent interface cases 
It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.

This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.

Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.

This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
