The Multi-AP specification adds a new subelement to the WFA extension
element in the WPS exchange. Add an additional parameter to
wps_build_wfa_ext() to add this subelement. The subelement is only added
if the parameter is nonzero. Note that we don't reuse the existing
MULTI_AP_SUB_ELEM_TYPE definition here, but rather define a new
WFA_ELEM_MULTI_AP, to make sure the enum of WFA subelement types for WPS
vendor extension remains complete.
For now, all callers set the multi_ap_subelem parameter to 0.

Add P2PS config flag only when config_methods are set. This restores the
pre-P2PS behavioer for the cases where Display or Keypad config method
is specified for a peer (i.e., do not add the new P2PS method in that
case).

When sending a GO Negotiation Request, advertise the preferred frequency
list in a new vendor specific IE. This can be used to extend the
standard P2P behavior where a single preferred channel can be advertised
by allowing a priority list of channels to be indicated.

Fix a condition when Advertised Service Info Attribute is added to
a probe response in p2p_buf_add_service_instance(). The issue is
that a 'found' value is increased even if 'test' and 'adv->hash' hashes
are different. As result 'found' may have a non-zero value when an
attribute data length is 0. In this cause an empty attribute is about to
be added. Fixing it by eliminating 'found' and checking 'total_len'
containing a real number of bytes added to Advertised Service Info
Attribute.
This fixes an issue from commit 50a9efe713
('P2PS: Fix Probe Response frame building in error cases').

org.wi-fi.wfds service is not a replacement for non-WFA service matches.
Do not try to replace the results with that if there is not sufficient
room for the response. Instead, reply with all the matching services
that fit into the message. org.wi-fi.wfds is the first entry in the list
(if matching request/service is present), so it won't get overridden by
other services.

The service hash for org.wi-fi.wfds is supposed to match only if the

Quoting P2PS specification: "If multiple Service Hash values are
included in the Probe Request frame, then the ASP shall find a match for
each Service Hash, and it shall send a Probe Response frame with the
information listed in this section for all matched Service Hashes." This
commit changes handling of wildcard hash matching by adding a
wildcard 'org.wi-fi.wfds' info together with the other hash matches.

Avoid using p2p_data::query_hash for both Probe Request frame processing
and for hashes specified by p2p_find. It's resolved by use of local
query_hash and query_count variables in p2p_reply_probe().
Since p2p_data::query_hash is used only for seek hash values rename
p2p_data::query_hash to p2ps_seek_hash.
Delete p2p_data::query_count since it's not needed anymore.

Previously, both this and combination of OUI_WFA and P2P_OUI_TYPE were
used. Using the full 32-bit value as a single operation saves a bit in
code size, so start moving towards using it more consistently when
writing or finding the P2P vendor specific element.

Use Device Password ID in WSC IE of Probe Request and Probe Response
frames to advertise immediate availability of WPS credentials per P2P
specification sections 3.1.2.1.1 (Listen State), 3.1.2.1.2 (Scan Phase),
and 3.1.2.1.3 (Find Phase).
For now, the Device Password ID is set only for the case where we are
active GO Negotiation with a specific peer. In practice, this means that
the Probe Response frames during pending GO Negotiation (whenever in
Listen state) indicate availability of the credential.

The default config methods was hardcoded to claim support for
PushButton, Display, and Keypad. While these are supported by
most P2P devices, there may be some cases where it is convenient
to be able to disable a specific config method. Use config_methods
configuration parameter to set the default values for Config Methods
in the P2P Device Info attribute.
The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label
config method.
When building IE from an empty string and CONFIG_WPS_STRICT is
not defined, redundant 2 bytes are being added to the string.
We have to return right after building the "dummy" string.

If the peer is not authorized for GO Negotiation, wps_method is not
actually set. In that case, it is better to fill in our default
config methods rather than end up leaving the field to be zero.
