a16514516b Add "GET tls_library" to provide information on TLS library and version
This new wpa_supplicant and hostapd control interface command can be
used to determine which TLS library is used in the build and what is the
version of that library.

a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

If the RADIUS server includes deauthentication request in Access-Accept,
send a WNM-Notification frame to the station after 4-way handshake and
disconnect the station after configurable timeout.

A new control interface command, WNM_DEAUTH_REQ, is added for testing
purposes to allow the notification frame to sent based on local request.
This case does not disconnect the station automatically, i.e., a
separate control interface command would be needed for that.

5bbf590a58 hostapd: Android: Force group access to ctrl_iface directory
Same fix as d49ea68284 in
wpa_supplicant.

From original commit:

wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.
