Previously, an unexpected SAE commit message resulted in forcing
disconnection. While that allowed recovery by starting from scratch,
this is not really necessary. Ignore such unexpected SAE commit message
instead and allow SAE confirm message to be processed after this. This
is somewhat more robust way of handling the cases where SAE commit
message might be retransmitted either in STA->AP or AP->STA direction.

wpa_key_mgmt_wpa_psk() includes SAE AKMs. However, with SAE, there is no
way of reaching 4-way handshake without the password having already been
verified as part of SAE authentication. As such, a failure to complete
4-way handshake with SAE cannot indicate that the used password was
incorrect.

To config BT coex chain mode, add a new QCA sub command
QCA_NL80211_VENDOR_SUBCMD_BTC_CHAIN_MODE.
This new command has two attributes:
1. QCA_VENDOR_ATTR_COEX_BTC_CHAIN_MODE: u32 attribute. Indicates the
BT coex chain mode, are 32-bit values from enum qca_btc_chain_mode.
2. QCA_VENDOR_ATTR_COEX_BTC_CHAIN_MODE_RESTART: flag attribute.
If set, vdev should be restarted once BT coex chain mode is updated.

The QCA_NL80211_VENDOR_SUBCMD_OEM_DATA command was previously defined
only to pass data blobs from user space to kernel (application to
firmware) but there was no mechanism to send the data blobs from
firmware to application. Extend this to define use of the same
subcommand and attributes as vendor events.

If hostapd had existing STA SAE state, e.g., from a previously completed
SAE authentication, a new start of a separate SAE authentication (i.e.,
receiving of a new SAE commit) ended up using some of the previous
state. This is problematic for determining whether to H2E vs. looping
since the STA is allowed (even if not really expected to) to change
between these two alternatives. This could result in trying to use H2E
when STA was using looping to derive PWE and that would result in SAE
confirm failing.
Fix this by determining whether to use H2E or looping for the restarted
authentication based on the Status Code in the new SAE commit message
instead of previously cached state information.

Remove support for performing full sqrt(), i.e., only support curves
that use prime with p = 3 mod 4. In practice, this drops only group 26
with SAE H2E. This seems acceptable since there does not seem to be any

placed on acceptable prime lengths.

It looks like the wpa_auth_get_seqnum() function might not always be
visible in the backtrace since the compiler may optimize that wrapper
away. Use the i802_get_seqnum() function instead as a trigger for the
get_seqnum operation failure trigger to avoid this.

In the SME-in-driver case, wpa_supplicant used only the selected SAE
auth_alg value as the trigger for enabling external authentication
support for SAE. This prevented the driver from falling back to full SAE
authentication if PMKSA caching was attempted (Open auth_alg selected)
and the cached PMKID had been dropped.
Enable external auth based on SAE/FT-SAE key_mgmt, rather than doing
this based on SAE auth_alg, so that the driver can go through full SAE
authentication in cases where PMKSA caching is attempted and it fails.
