Earlier, the OCE flags were checked during hostapd initialization. This
doesn't address few cases like for example when the interface is added
from control interface. Move the OCE flag checks to the functions that
are forming the MBO/OCE IEs to cover all the different paths for
enabling a BSS. Also use macros as appropriate for readability.

The new acs_exclude_dfs=1 parameter can be used to request hostapd to
exclude all DFS channels from ACS consideration. This is mainly of use
for cases where the driver supports DFS channels, but for some reason a
non-DFS channel is desired when using automatic channel selection.
Previously, the chanlist parameter could have been used for this, but
that required listing all the acceptable channels. The new parameter
allows this to be done without such a list.

IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS. hostapd used
to use the actual BSSID value for all such frames regardless of whether
the destination STA is a member of the BSS.
Fix this by using the wildcard BSSID in cases the destination STA is not
a member of the BSS. Leave group addressed case as-is (i.e., the actual
BSSID), since both values are accepted. No such frames are currently
used, though.
This version is still using the AP BSSID value in the Address 3 field
for GAS response frames when replying to a GAS request with AP BSSID
instead of Wildcard BSSID. This is left as a workaround to avoid
interoperability issues with deployed STA implementations that are still
using the non-compliant address and that might be unable to process the
standard compliant case.

Add support for drivers that support full AP client state, i.e., can
handle adding stations that are not associated yet. For such drivers,
add a station after processing the authentication request, instead of
adding it in the association response callback.
Doing so is beneficial in cases where the driver cannot handle the add
station request, in which case it is useless to perform the complete
connection establishment.

When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.
In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.
Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.

Commit 95b6bca66d ('Add rsn_pairwise bits
to set_ieee8021x() driver_ops') modified cipher configuration to use
unconditionally wpa_pairwise | rsn_pairwise. While that works for many
cases, it does not handle the case of dynamic configuration changes over
the control interface where wpa_pairwise or rsn_pairwise values may not
get cleared when the wpa parameter is modified. Fix this inconsistency
by configuring the driver with only the bits that are valid for the
currently enabled WPA/WPA2 version(s).

This fixes an issue where a driver using the deprecated set_ieee8021x()
callback did not include rsn_pairwise bits in the driver configuration
even if mixed WPA+WPA2 configuration was used. This could result, e.g.,
in CCMP not being enabled properly when wpa_pairwise=TKIP and
rsn_pairwise=CCMP was used in the configuration. Fix this by using
bitwise OR of the wpa_pairwise and rsn_pairwise values to allow the
driver to enable all pairwise ciphers.
In addition, make the newer set_ap() driver_ops use the same bitwise OR
design instead of picking between rsn_pairwise and wpa_pairwise. This
makes the code paths consistent and can also fix issues with mixed mode
configuration with set_ap().
