wsc_pin_is_valid allows two types of PINs through:
1. 4 digit numeric PIN
2. 8 digit numeric PIN
The current code always calls wsc_pin_is_checksum_valid to determine
whether a DEFAULT or USER_SPECIFIED PIN is used. However, this function
is not safe to call on 4 digit PINs and causes a buffer overflow.
Add simple checks to treat 4 digit PINs as DEFAULT PINs and do not call
wsc_pin_is_checksum_valid on these.

EAP-WSC handles 4 digit, 8 digit and out-of-band Device passwords. The
latter in particular can be anything, so drop the mandatory minimum
password length check here.
This also has the effect of enabling 4-digit PINs to actually work as
they are intended.
The struct allows to support multiple types of the tunneled methods.
Previously, EAP-TTLS was supporting only the eap based ones.
This patch is also starts to move some of the phase 2 EAP
functionality into the new structure.
This test was copied from testFT-PSK-roam, but for SAE. The test behaves
as follows:
- Connect to SAE network (full authentication)
- Fast transition to another SAE AP
- Fast transition to a PSK/WPA2 AP
Boiled down, FT over SAE is no different than FT over PSK, apart from
the different AKM suite. The bulk of this change fixes the current
netdev/station logic related to SAE by rebuilding the RSNE and adding
the MDE if present in the handshake to match what the PSK logic does.
A common function was introduced into station which will rebuild the
handshake rsne's for a target network. This is used for both new
network connections as well as fast transitions.
To prepare for FT over SAE, several case/if statements needed to include
IE_RSN_AKM_SUITE_FT_OVER_SAE. Also a new macro was introduced to remove
duplicate if statement code checking for both FT_OVER_SAE and SAE AKM's.
All the watchlist notify macros were broken in that they did not check
that the watchlist item was still valid before calling it. This only
came into play when a watchlist was being notified and one of the notify
functions removed an item from the same watchlist. It appears this was
already thought of since watchlist_remove checks 'in_notify' and will
mark the item's id as stale (0), but that id never got checked in the
notify macros.

This is a temporary fix to address the recent split of
the Device interface. This patch contains a workaround that
re-enables the auto-tests while the test framework is being
reworked to satisfy the need of the new API and should not
be considered as a permanent solution.
In the case of the open networks with hidden SSIDs
the settings object is already created.

Station, WSC, Ad-Hoc and AP family_arg_completion functions were
identical except for which commands they were referencing and the
interface type they were interested in. Combine all these into a single
function.
