[RFC 00/56] Initial NAN R2 module support

[Andrei Otcheretianski]

This series is an RFC initial proposal for NAN R2 module implementation.
This includes an implementation for NDP and NDL state machines including
the security negotiation.

These patches should be applied on top of the rebased "Add initial
support for NAN synchronized discovery" patch series.

In this submission, we only include the NAN data path module
implementation, without any layer which connects it to wpa_supplicant
and driver APIs. Testing coverage is done using module tests.

Design summary:
NDP establishment is triggered using nan_handle_ndp_setup() function
which is called both for triggering NDP request and replying to an
incoming ndp request. nan_action_rx(), nan_tx_status() and send_naf()
callback are used to send and receive NAFs and their statuses in the NAN
module. ndp_action_notif() callback is used to notify about the incoming NDP
request/counter response events. ndp_[dis]connected() callbacks are
called upon completion of NDP and NDL establishment.

In the current design, NDP and NDL state machines are managed in the NAN
module. Note that NDL SM doesn't manage actual device scheduling and it
is assumed that the schedule is configured outside of NAN module and
provided as part of nan_ndp_params struct. Having said that, NAN module
manages NDL state transitions and decides internally whether to
accept/counter or reject the NDL establishment based on the configured
schedule, NDC, QoS parameters etc.

Upper layers (wpa_supplicant, ctrl_iface, driver) are expected to be
able to configure the underlying device with the provided schedule and
configure the corresponding peer schedule. The derived NDP parameters
(peer NDI address and keys) are either provided as part of NDP
notifications or can be queried via provided APIs. wpa_supplicant should
be able to configure this information to the underlying device.

Wpa_supplicant, ctrl_iface and driver corresponding implemenation will
be submitted separately.
