This avoid incorrect errors from some static analyzers that do not like
memmove with pointers just after the end of a buffer even if the number
of bytes to move is zero.

Some drivers do not handle concurrent remain-on-channel operation
requests, so run p2p_stop_find() prior to starting p2p_listen. This
addresses some issues with P2P_LISTEN command being issues again
while already in Listen state.

If a P2P client associates with the group while it is
already associated, two member entries may be added to
the group which also confuses num_members counting.
Deal with this by removing the existing entry first
before adding a new one.
I think the way Reinette ran into this was due to our
tx_sync implementation in iwlagn, mac80211 might have
queued two association frames thinking the first one
just failed, but both only went out after the sync was
really successful (which tx_sync doesn't wait for).

In AP mode, authentication algorithm is reset in
hostapd_config_defaults_bss() and never set to the configured one. This
would pass the default auth_algs (OPEN|SHARED) to driver regardless of
what the wpa_supplicant configuration is requesting.

Use a temporary PTK buffer during 4-way handshake when rekeying PTK
so that the new EAPOL-Key frame MIC values are checked against the
new PTK and frames are decrypted using the old PTK. Take the new
PTK into use once msg 4/4 is processed and clear RSC counters at
that point (including moving of RSC update to avoid setting RSC
based on the msg 4/4).
In addition, add a workaround to handle supplicant implementations that
set Secure bit to one during PTK rekeying 4-way handshake in msg 2/4.
This was previously assumed to be msg 4/4, but the key data contents
can be used to figure out whether this is msg 2/4 even if the Secure
bit is set to one.

This function can fail in theory since the SHA-1 functions are
allowed to return an error. While this does not really happen in
practice (we would not get this far if SHA-1 does not work), it is
cleaner to include the error handling here to keep static analyzers
happier. [Bug 421]

Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
