1825fd7ab7 auto-t: iwd.py: fix namespaces on StationDebug
Passing the full argument list to StationDebug was removed
because any existing properties (for Device) were being
included and causing incorrect behavior.

This neglected to handle namespaces which should also be
passed to StationDebug. Unfortunately the arguments are not
named when Device() is initialized so they cannot easily be
sorted. Instead just define Device() arguments to match the
DBus abstraction and pass only the path and namespace to
StationDebug

ba040219ce client: add DPP client commands
Two commands were added:

dpp <iface> start-enrollee
dpp <iface> start-configurator
dpp <iface> stop

In addition there is support for using the qrencode utility for displaying
the QR code after DPP is started (enrollee or configurator. If qrencode is
found on the system the QR code will be displayed. Otherwise only the URI
will be printed to the console.

1a9734d704 dpp: implement configurator role
This implements a configurator in the responder role. Currently
configuring an enrollee is limited to only the connected network.
This is to avoid the need to go offchannel for any reason. But
because of this a roam, channel switch, or disconnect will cause
the configuration to fail as none of the frames are being sent
offchannel.

ec0f4e8826 dpp: add role definitions
Added both enrollee and configurator roles, as well as the needed
logic inside the authentication protocol to verify role compatibility.
The dpp_sm's role will now be used when setting capability bits making
the auth protocol agnostic to enrollees or configurators.

8f711078b8 dpp: add timeout for auth/config protocols
This also allows the card to re-issue ROC if it ends in the middle of
authenticating or configuring as well as add a maximum timeout for
auth/config protocols.

IO errors were also handled as these sometimes can happen with
certain drivers but are not fatal.

c42080fe28 dpp: use frame data directly in unwrap for config response
Rather than hard coding ad0, use the actual frame data. There really
isn't a reason this would differ (only status attribute) but just
in case its better to use the frame data directly.

926c8bb9bd dpp: add support for configuration protocol
This is a minimal implementation only supporting legacy network
configuration, i.e. only SSID and PSK/passphrase are supported.

Missing features include:

 - DPP AKM support
 - 8021x/PKEX support

59a5cf3de4 dpp: add DPP authentication protocol
This implements the DPP protocol used to authenticate to a
DPP configurator.

Note this is not a full implementation of the protocol and
there are a few missing features which will be added as
needed:

 - Mutual authentication (needed for BLE bootstrapping)
 - Configurator support
 - Initiator role

683d3a3f04 dpp: send presence announcements on StartEnrollee
The presence procedure implemented is a far cry from what the spec
actually wants. There are two reason for this: a) the kernels offchannel
support is not at a level where it will work without rather annoying
work arounds, and b) doing the procedure outlined in the spec will
result in terrible discovery performance.

Because of this a simpler single channel announcement is done by default
and the full presence procedure is left out until/if it is needed.

abfd749335 json: introduce JSON module
This is a minimal wrapper around jsmn.h to make things a bit easier
for iterating through a JSON object.

To use, first parse the JSON and create a contents object using
json_contents_new(). This object can then be used to initialize a
json_iter object using json_iter_init().

The json_iter object can then be parsed with json_iter_parse by
passing in JSON_MANDATORY/JSON_OPTIONAL arguments. Currently only
JSON_STRING and JSON_OBJECT types are supported. Any JSON_MANDATORY
values that are not found will result in an error.

If a JSON_OPTIONAL string is not found, the pointer will be NULL.
If a JSON_OPTIONAL object is not found, this iterator will be
initialized but 'start' will be -1. This can be checked with a
convenience macro json_object_not_found();

d65aaf8740 dpp-util: check return of l_ecc_scalar_get_data
Static analysis was not happy since this return can be negative and
it was being fed into an unsigned argument. In reality this cannot
happen since the key buffer is always set to the maximum size supported
by any curves.

bc36aca98e offchannel: introduce new offchannel module
This module provides a convenient wrapper around both
CMD_[CANCEL_]_REMAIN_ON_CHANNEL APIs.

Certain protocols require going offchannel to send frames, and/or
wait for a response. The frame-xchg module somewhat does this but
has some limitations. For example you cannot just go offchannel;
an initial frame must be sent out to start the procedure. In addition
frame-xchg does not work for broadcasts since it expects an ACK.

This module is much simpler and only handles going offchannel for
a duration. During this time frames may be sent or received. After
the duration the caller will get a callback and any included error
if there was one. Any offchannel request can be cancelled prior to
the duration expriring if the offchannel work has finished early.

7ecdee6eaa autotests: p2p: Make waiting for dhclient more reliable
Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply.  Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start.  Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.
