The new TEST_FAIL and GET_FAIL control interface commands can be used
similarly to the earlier TEST_ALLOC_FAIL/GET_ALLOC_FAIL design. The new
version is more generic framework allowing any function to be annotated
for failure testing with the TEST_FAIL() macro. This mechanism is only
available in builds with CONFIG_WPA_TRACE_BFD=y and
CONFIG_TESTING_OPTIONS=y. For other builds, the TEST_FAIL() macro is
defined to return 0 to allow the compiler to remove the test code from
normal production builds.
As the first test site, allow os_get_random() to be marked for failing
based on call backtrace.

Do not allow 40 MHz co-ex PRI/SEC switch to force us to change our PRI
channel if we have an existing connection on the selected PRI channel
since doing multi-channel concurrency is likely to cause more harm than
using different PRI/SEC selection in environment with multiple BSSes on
these two channels with mixed 20 MHz or PRI channel selection.

Fix a condition when Advertised Service Info Attribute is added to
a probe response in p2p_buf_add_service_instance(). The issue is
that a 'found' value is increased even if 'test' and 'adv->hash' hashes
are different. As result 'found' may have a non-zero value when an
attribute data length is 0. In this cause an empty attribute is about to
be added. Fixing it by eliminating 'found' and checking 'total_len'
containing a real number of bytes added to Advertised Service Info
Attribute.
This fixes an issue from commit 50a9efe713
('P2PS: Fix Probe Response frame building in error cases').

In p2p_find command line processing a loop searching for multiple
'seek=' parameters modifies cmd buffer adding '\0' terminators.
The 'freq=' parameter is handled after that and can be
lost if a 'freq=' follows 'seek=' in a command line.
Fix it by moving a handling of 'freq=' parameter to be processed
before 'seek=' handling loop.

The cwmin/cwmax parameters were limited more than is needed. Allow the
full range (0..15 for wmm_ac_??_{cwmin,cwmax} and 1..32767 for
tx_queue_data?_{cwmin,cwmax}) to be used.

The current P802.11 description of SAE uses "1 < element < p" as the
required range. However, this is not correct and does not match the
Dragonfly description of "1 < element < p-1". SAE definition will need
to change here. Update the implementation to reject p-1 based on the
correct rule here.

It was possible for the P2PS Probe Response frame to go out on the
channel on which a Probe Request frame was reported even when we are
just about to start Listen mode on another channel. This could result in
the peer device using incorrect channel for us. Fix this by skipping the
response in this special case while waiting for Listen mode to start.
This showed up as a hwsim test failure with test sequence "gas_fragment
p2ps_connect_display_method_nonautoaccept" in cases where the dev[0]
Listen channel was not same as the AP operating frequency in the GAS
test.

IEEE Std 802.11-2012 description of SAE does not require this, i.e., it
describes the requirement as 0 < scalar < r for processing the Commit
message. However, this is not correct and will be changes to 1 < scalar
< r to match the Dragonfly description so that a trivial secret case
will be avoided explicitly.
This is not much of an issue for the locally generated commit-scalar
since it would be very unlikely to get the value of 1. For Commit
message processing, a peer with knowledge of the password could
potentially force the exchange to expose key material without this
check.

wpa_supplicant has stub functions if the external p2p symbols are
unavailable, but the build still fails if the
wpa_driver_nl80211_driver_cmd symbol is missing. Fix this by leaving the
function pointer NULL. This is safe because wpa_drv_driver_cmd() performs
a NULL check.

If BOARD_HOSTAPD_PRIVATE_LIB is not used on an Android build, we will
need to replace both the p2p functions *and* wpa_driver_nl80211_driver_cmd
in order to successfully link. Let's make the name more generic so it is
more obvious what it is used for.

Even though this OpenSSL function is documented as returning "1 if point
if on the curve and 0 otherwise", it can apparently return -1 on some
error cases. Be prepared for that and check explicitly against 1 instead
of non-zero.

This replaces the earlier IEEE Std 802.11-2012 algorithm with the design
from P802.11-REVmc/D4.0. Things brings in a blinding technique for
determining whether the pwd-seed results in a suitable PWE value.
