It was possible to find a BSS to local network profile match for a BSS
entry that has no known SSID when going through some of the SSID
wildcard cases. At leas the OWE transition mode case without BSSID match
could result in hitting this. Zero-length SSID (i.e., wildcard SSID) is
not valid in (Re)Association Request frame, so such an association will
fail. Skip such a BSS to avoid known-to-be-failing association attempts.

While it is appropriate to try to retransmit the event to another
callback URL on a failure to initiate the HTTP client connection, there
is no point in trying the exact same operation multiple times in a row.
Replve the event_retry() calls with event_addr_failure() for these cases
to avoid busy loops trying to repeat the same failing operation.
These potential busy loops would go through eloop callbacks, so the
process is not completely stuck on handling them, but unnecessary CPU
would be used to process the continues retries that will keep failing
for the same reason.

More than about 700 character URL ended up overflowing the wpabuf used
for building the event notification and this resulted in the wpabuf
buffer overflow checks terminating the hostapd process. Fix this by
allocating the buffer to be large enough to contain the full URL path.
However, since that around 700 character limit has been the practical
limit for more than ten years, start explicitly enforcing that as the
limit or the callback URLs since any longer ones had not worked before
and there is no need to enable them now either.

The UPnP Device Architecture 2.0 specification errata ("UDA errata
16-04-2020.docx") addresses a problem with notifications being allowed
to go out to other domains by disallowing such cases. Do such filtering
for the notification callback URLs to avoid undesired connections to
external networks based on subscriptions that any device in the local
network could request when WPS support for external registrars is
enabled (the upnp_iface parameter in hostapd configuration).

This replaces the previously used sae_pk_only configuration parameter
with a more generic sae_pk that can be used to specify how SAE-PK is
negotiated. The default behavior (sae_pk=0) is to automatically
negotiate SAE-PK whenever the AP supports it and the password is in
appropriate format. sae_pk=1 allows only SAE-PK to be used and sae_pk=2
disables SAE-PK completely.

The wpa_supplicant control interface returns maximum of 4 kB of response
data and, thus, limits maximum number of scan entries as part of
SCAN_RESULTS to approximately 60. Add a new all_bss command to use a
more robust iteration of the BSS table entries with the BSS command to
to get all scan entries and print them in the same format as the
scan_results command.

wpa_supplicant disables PMKSA caching with FT-EAP by default due to
known interoperability issues with APs. This is allowed only if the
network profile is explicitly enabling caching with
ft_eap_pmksa_caching=1. However, the PMKID for such PMKSA cache entries
was still being configured to the driver and it was possible for the
driver to build an RSNE with the PMKID for SME-in-driver cases. This
could result in hitting the interop issue with some APs.
Fix this by skipping PMKID configuration to the driver fot FT-EAP AKM if
ft_eap_pmksa_caching=1 is not used in the network profile so that the
driver and wpa_supplicant behavior are in sync for this.
