Jouni Malinen d55fc03ef6 P2P: Handle unexpected GO Neg Req reject message more cleanly
The mechanism of using Status attribute in GO Negotiation Request was
used in some early specification drafts, but it is not compliant with
the current P2P specification where GO Negotiation Request is used only
for the purpose of initiating a new GO Negotiation. However, some
deployed devices use it to indicate rejection of GO Negotiation in a
case where they have sent out GO Negotiation Response with status 1. The
P2P specification explicitly disallows this.

To avoid unnecessary interoperability issues and extra frames, mark the
pending negotiation as failed and do not reply to this GO Negotiation
Request frame. Previously, GO Negotiation Response frame with status=4
was sent back as an indication of the GO Negotiation Request frame being
invalid. This response is not sent anymore and the status code for the
P2P-GO-NEG-FAILURE event is changed from 4 (invalid parameters) to 11
(rejected by user) for this specific workaround case.

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).
