Jouni Malinen b1f122964e Add generic GAS request mechanism
The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or
with other (including vendor specific) advertisement protocols.

gas_request <BSSID> <AdvProtoID> [Query]
gas_response_get <addr> <dialog token> [offset,length]

For example, ANQP query for Capability list in interactive wpa_cli
session:

> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0
status_code=0 resp_len=32
> gas_response_get 02:00:00:00:01:00 00
01011c00010102010501070108010c01dddd0c00506f9a110200020304050607
> gas_response_get 02:00:00:00:01:00 00 0,10
01011c00010102010501
> gas_response_get 02:00:00:00:01:00 00 10,10
070108010c01dddd0c00
> gas_response_get 02:00:00:00:01:00 00 20,10
506f9a11020002030405
> gas_response_get 02:00:00:00:01:00 00 30,2
0607

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

All Rights Reserved.

These programs are licensed under the BSD license (the one with
advertisement clause removed).

If you are submitting changes to the project, please see CONTRIBUTIONS
file for more instructions.


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).
