Add the ability to ignore time-based CRL errors from OpenSSL by
specifying a new configuration parameter, check_crl_strict=0.
This causes the following:
- This setting does nothing when CRL checking is not enabled.
- When CRL is enabled, "strict mode" will cause CRL time errors to not
be ignored and will continue behaving as it currently does.
- When CRL is enabled, disabling strict mode will cause CRL time
errors to be ignored and will allow connections.
By default, check_crl_strict is set to 1, or strict mode, to keep
current functionality.

handle_dhcp() was first trying to learn the IP address of an associated
STA before doing broadcast-to-unicast conversion. This could result in
not converting some DHCPACK messages since the address learning part
aborts processing by returning from the function in various cases.
Reorder these operations to allow broadcast-to-unicast conversion to
happen even if an associated STA entry is not updated based on a
DHCPACK.

IEEE Std 802.1X-2010, 11.11 describes that the ICV is separate from the
parameter sets before it. Due to its convenient layout the ICV Indicator
'body part' is used to encode the ICV as well.
IEEE Std 802.1X-2010, 11.11.3 describes the encoding of MKPDUs. In
bullet e) is desribed that the ICV Indicator itself is encoded when the
ICV is not 16 octets in length. IEEE Std 802.1Xbx-2014, Table 11-7 note
e) states that it will not be encoded unless the Algorithm Agility
parameter specifies the use of an ICV that is not 16 octets in length.
Therefore the length calculation for the ICV indicator body part must
take into account if the ICV Indicator is to be encoded or not. The
actual encoder of the ICV body already takes care of the rest.
In practice, this change will remove the ICV Indicator parameter set (4
octets before the ICV value itself) since the only defined algorithm
agility value uses an ICV of 16 octets. IEEE Std 802.1X-2010 MKPDU
validation and decoding rules in 11.11.2 and 11.11.4 require the
receipient to handle both cases of ICV Indicator being included or not.

The ap_open_tdls_vht* test cases could leave some pending regulatory
Beacon hints waiting to be cleared during the following test case. This
would result in a failure if the following test case expected specific
regdom event behavior. For example, this caused "ap_open_tdls_vht160
dbus_country" sequence to result in failure in dbus_country. Fix this by
using more robust sequence in clearing regdom state at the end of the
TDLS test cases that have the AP advertising a country code.

It was possible for a participant to first be elected as a key server
and schedule a new SAK to be generated and distributed just to be
followed by another participant being elected as the key server. That
did not stop the participant that disabled key server functionality to
stop generating the new SAK and then trying to distribute it. That is
not correct behavior, so make these steps conditional on the participant
still being a key server when going through the timer.

This pointer needs to be cleared when the matching SAK is being removed
from the SAK list. The previous implementation was doing something
pretty strange in the loop by clearing the pointer for any non-matching
key that happened to be iterated through before finding the matching
key. This could probably result in incorrect behavior, but not clearing
the pointer for the matching key could do more harm by causing freed
memory to be referenced.

While IEEE Std 802.1X-2010 talks about arbitrary authorization data that
could be passed to the CP from sources like RADIUS server, there is not
much point in trying to implement this as an arbitrary memory buffer in
wpa_supplicant. Should such data be supported in the future, it would
much more likely use more detailed data structures that encode the
received data in easier to use form.

from its live peers list but the server still thinks that the peer is
alive (e.g., high packet loss in one direction). In such a case, the Key
