When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.
There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the
joining mesh STA. However, a STA that is already a member of existing
mesh BSS should not retry connection because if the joining mesh STA
used wrong password, all the existing STA should do something from UI to
retry connection.

Send MESH-SAE-AUTH-BLOCKED event if SAE authentication is blocked. The
BLOCK state will finish when a new peer notification event is sent for
the same MAC address.

SAE authentication fails likely with wrong password. This commit adds a
notification of the failure to the upper application (UI) so that the
application can notify suspection of a wrong password to the user. The
control interface monitor even for this is "MESH-SAE-AUTH-FAILURE
addr=<peer>".

The plink_state exists both wpa_supplicant and kernel. Synchronize them
with wpa_mesh_set_plink_state().

When performing SAE authentication in mesh, one station may
initiate authentication by sending a COMMIT as soon as a peer
candidate is discovered. Previously we did this in mesh_rsn.c,
but this left some of the state initialization in a different
part of the code from the rest of the state machine, and we may
need to add other initializations here in the future, so move
that to a more central function.

This converts most of the remaining perror() and printf() calls from
hostapd and wpa_supplicant to use wpa_printf().

It is possible that these location ended up getting called before mesh
startup operations had been completed and that could result in
dereferencing NULL pointers. Address those error cases by verifying that
the needed parameters are available before using them.

Add timer to do SAE re-authentication with number of tries defined
by MESH_AUTH_RETRY and timeout defined by MESH_AUTH_TIMEOUT.
Ignoring the sending of reply message on "SAE confirm before commit"
to avoid "ping-pong" issues with other mesh nodes. This is obvious when
number of mesh nodes in MBSS reaching 6.
