Add configuration of Spectrum Management subfield in the Capability

Confirm-before-commit validation step allowed execution to continue on
error case. This could result in segfault in sae_check_confirm() if the
temporary SAE data was not available (as it would not be, e.g., in case
of an extra SAE confirm message being received after successful
exchange). Fix this by stopping SAE processing immediately after
detecting unexpected state for confirm message. In addition, make the
public sae.c functions verify sae->tmp before dereferencing it to make
this type of bugs less likely to result in critical issues.

When GAS is used with PMF negotiated, Protected Dual of Public Action
frames are expected to be used instead of Public Action frames, i.e.,
the GAS/ANQP frames are expected to be encrypted. Add support for this
different category of Action frames being used for GAS. The payload
after the Category field is identical, so the only change is in using
the Category field based on what was received in the request frames. For
backwards compatibility, do not enforce protected dual to be used on the
AP side, i.e., follow what the station does.

Due to misplaced parenthesis, unprotected not-Robust Action frames
(e.g., Public Action frames) were dropped in handle_assoc() when such
frames were received during an association that had negotiated use of
PMF. This is not correct since only unprotected Robust Action frames
were supposed to be handled in this way.
This would have broken any Public Action frame use during PMF
association, but such frames were not really supposed to be used
currently (ANQP as the only possible use case should really use
protected dual option in such case).

This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

Commit 88b32a99d3 added support for using
some Action frame processing in hostapd for drivers that handle most of
SME/MLME internally (it added FT, this has since be extended for SA
Query and WNM). However, this was added in a way that ended up getting
both the hostapd_rx_action() and hostapd_action_rx() called for Action
frames. This could result in an attempt to process FT, SA Query, and WNM
Action frames twice.
There is need for more significant cleanup in Action frame processing in
hostapd depending on the driver type, but as a simple step to avoid
issues, skip the hostapd_action_rx() call if hostapd_rx_action()
processed the frame.

This enables more convenient protocol testing of station side

Currently, hostapd_get_vlan_id_ifname() is used to determine if a given
vlan is valid *and* to actually determine the interface. This leads to
wpa_set_keys() sometimes setting the key on the wildcard interface name,
which does not make sense.
This patch therefore adds hostapd_vlan_id_valid() and makes
hostapd_get_vlan_id_ifname() not return a wildcard interface.

GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.
