Normally, WNM-Sleep Mode exit with management frame protection
negotiated would result in the current GTK/IGTK getting added into the
WNM-Sleep Mode Response frame. Some station implementations may have a
vulnerability that results in GTK/IGTK reinstallation based on this
frame being replayed. Add a new hostapd configuration parameter that can
be used to disable that behavior and use EAPOL-Key frames for GTK/IGTK
update instead. This would likely be only used with
wpa_disable_eapol_key_retries=1 that enables a workaround for similar
issues with EAPOL-Key. This is related to station side vulnerabilities
CVE-2017-13087 and CVE-2017-13088. To enable this AP-side workaround,
set wnm_sleep_mode_no_keys=1.

When strict group rekeying is in effect, every station that leaves will
cause a rekeying to happen 0.5 s after leaving. However, if a lot of
stations join/leave, the previous code could postpone this rekeying
forever, since it always re-registers the handling with a 0.5 s timeout.
Use eloop_deplete_timeout() to address that, only registering the
timeout from scratch if it wasn't pending.

Previously, Initiator decided whether to use mutual authentication on
its own based on having own and peer bootstrapping info. This prevented
Responder from selecting not to use mutual authentication in such a
case. Fix this by allowed Initiator to fall back to non-mutual
authentication based on Responder choice if the bootstrapping mechanism
allows this (PKEX does not; it mandates use of mutual authentication).

This cleans up old dpp_auth_build_resp() (now dpp_auth_build_resp_ok())
a bit by separating initialization steps for a DPP authentication
session from the code needed to build the frame. This allows
dpp_auth_build_resp_status() to share the helper function instead of
having to maintain a duplicated message construction implementation. In
addition, this makes it easier to remove some of the attributes for
protocol testing purposes.

Add a generic mechanism for configuring the DPP implementation to behave
in particular different (mostly incorrect) ways for protocol testing

Seems like some test cases, e.g., ap_wpa2_psk_ext_retry_msg_3c, require
larger buffer than 256 bytes.
In other case I fail such test cases when run on real HW and using:
