Michael Braun c5fee1604b FT: Schedule wpa_ft_rrb_rx() through eloop in intra-process communication 
With AP-AP communication, when hapd0 sends a packet, hapd1 can receive
it immediately and send a response. But hapd0 will only read and process
the response after it has returned from the sending context, that is
entered eloop again. So one does not need to consider the RX function of
the reply to run for the request sending hapd before the send calling
function has returned.

Previously, with intra-process communication, the packet is not
scheduled through eloop. Thus the RX handler of the reply might be run
while the sending context of the original request has not returned.
This might become problematic, e.g., when deferring a management frame
processing until an RRB response is received and then have the request
restarted and finished before the original request handling has been
stopped.

I'm not aware of any concrete bug this is currently triggering but came
across it while thinking of FT RRB AP-AP sequence numbering.

I think the non-eloop scheduling approach might be error-prone and thus
propose to model it more closely to the way the message would be
received from a socket. Additionally, this ensures that the tests model
AP-AP communication more closely to real world.

Solution: queue these packets through eloop.

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).
