Jouni Malinen 2b12b3602a P2P: Do not reply to GO Negotiation Request if peer is waiting for us 
This improves robustness of GO Negotiation in special cases where GO
Negotiation Request frames from the peer may end up getting delivered
multiple times, e.g., due to interference and retransmitted frames not
getting properly filtered out in duplicate detection (which is something
that number of drivers do not implement for pre-associated state).

If we have already replied with GO Negotiation Response frame with
Status 1 (not yet ready), do not reply to another GO Negotiation Request
frame from the peer if we have already received authorization from the
user (P2P_CONNECT command) for group formation and have sent out our GO
Negotiation Request frame. This avoids a possible sequence where two
independent GO Negotiation instances could go through in parallel if the
MAC address based rule on avoiding duplicate negotiations is not able to
prevent the case. This can allow GO Negotiation to complete successfully
whereas the previous behavior would have likely resulted in a failure
with neither device sending a GO Negotiation Confirm frame.

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).
