3ce48c440e HS 2.0: Fix PMF-in-use check for ANQP Venue URL processing
The previous implementation did not check that we are associated with
the sender of the GAS response before checking for PMF status. This
could have accepted Venue URL when not in associated state. Fix this by
explicitly checking for association with the responder first.

This fixes an issue that was detected, e.g., with these hwsim test case
sequences:
gas_anqp_venue_url_pmf gas_anqp_venue_url
gas_prot_vs_not_prot gas_anqp_venue_url

aca4d84e3d DPP: Use wildcard BSSID in GAS query frames
Force use of the wildcard BSSID address in GAS query frames with DPP
regardless of how the gas_address3 configuration parameter is set. DPP
specification mandates this and the use of GAS here is really outside
the context of a BSS, so using the wildcard BSSID makes sense even for
the corner case of Configurator running on a known AP (where IEEE 802.11
standard would allow the BSSID of the AP to be used).

d6e93d3e09 GAS: Remove unused gas_query_cancel()
This function was added with the initial GAS implementation, but there
was no user for it at the time and no clear use now either, so remove
the unused function and the related GAS query reason code.

c5a64e2d51 GAS client: Use Protected Dual of Public Action frames with PMF
When GAS is used with PMF negotiated, Protected Dual of Public Action
frames are expected to be used instead of Public Action frames, i.e.,
the GAS/ANQP frames are expected to be encrypted. Conver Public Action
GAS queries to use Dual of Public Action frame if PMF has been
negotiated with the AP to which the frame is being sent.

b9e6d7001d Use radio work for GAS requests
Avoid concurrent GAS operations with any other exclusive use of the
radio by using the radio work queuing mechanism. This replaces some of
the earlier constraints on concurrent operations with the more generic
wpa_radio work concept.

cbc5484892 GAS: Do not start new scan operation during an ongoing GAS query
These operations can have conflicting offchannel requirements, so wait
with a new scan trigger until a pending GAS query has been completed.

04ea7b7947 GAS: Add a generic GAS query module
This implements GAS request mechanism that is aimed at being used to
replace use case specific GAS/ANQP implementations in the future.
Compared to the earlier implementation in P2P SD, this implementation
includes support for multiple concurrent requests and more thorough
validation of frames against the pending query data.

GAS header processing, including comeback and reassembly, are handled
within gas_query.c and the users of this module will only need to
provide the Query Request and process the (possibly reassembled)
Query Response.
