Use the information elements that were present in the (Re)Association
Request frame to derive the maximum bandwidth the AP will use to
transmit frames to a specific STA. By using this approach, we don't need
to query the kernel for this information, and avoid having to add a
driver API for that.

This adds support for hostapd-as-RADIUS-authentication-server to request
subscription remediation for SIM-based credentials. The new hostapd.conf
parameter hs20_sim_provisioning_url is used to set the URL prefix for
the remediation server for SIM provisioning. The random
hotspot2dot0-mobile-identifier-hash value will be added to the end of
this URL prefix and the same value is stored in a new SQLite database
table sim_provisioning for the subscription server implementation to

The previous implementation did not check that we are associated with
the sender of the GAS response before checking for PMF status. This
could have accepted Venue URL when not in associated state. Fix this by
explicitly checking for association with the responder first.
This fixes an issue that was detected, e.g., with these hwsim test case
sequences:
gas_anqp_venue_url_pmf gas_anqp_venue_url
gas_prot_vs_not_prot gas_anqp_venue_url

It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.
Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.
This fixes hwsim test case fils_sk_hlp_oom failures with unmodified
mac80211 implementation (i.e., with a relatively short retransmission
timeout for (Re)Association Request frame).
