This is needed to fix some sequencies where a real scan in ap_scan=2
case would be issued even when the connection case would expect direct
connection without a scan.
This fixed an issue shown in hwsim test case autoscan_exponential
followed by ibss_open_fixed_bssid.

This is needed to make following operations behave as expected since
mesh iftypes may prevent various operations (e.g., registering Probe
Request frame RX). Use same design as leave_ibss does to handle this
consistently.

It was possible for the ignore_if_down_event flag to remain set in some
cases where interface mode change required the interface to be set down
temporarily. If that happened, the following rfkill interface down could
have been ignored and device could have been left trying to scan or
connect (which would all fail due to the interface beign down). Clean
this up by clearing the ignore_if_down_event flag on the interface down
event regardless of whether the interface is up at the time this event
is processed.

Commit 6c6678e7a4 ('nl80211: Make
br_ifindex available in i802_bss') did not cover the case where
i802_check_bridge() ends up creating the bridge interface. That left
bss->br_ifindex zero and prevented neighbor addition. Extend that
functionality to update br_ifindex once the bridge netdev has been
added.

These need to be marked packed to avoid issues with compilers
potentially adding padding between the fields (e.g., gcc on 64-bit
seemed to make struct icmpv6_ndmsg two octets too long which broke IPv6
address discovery).

On Android, the control socket being used may be the socket that is
created when wpa_supplicant is started as a /init.*.rc service. Such a
socket is maintained as a key-value pair in Android's environment.
Closing this control socket would leave wpa_supplicant in a bad state.
When wpa_supplicant re-opens the ctrl_iface socket, it will query the
Android's environment, and will be returned with the same socket
descriptor that has already been closed.

This replaces the use of Linux kernel header files (linux/ip.h,
linux/udp.h, linux/ipv6.h, and linux/icmpv6.h) with equivalent header
files from C library. In addition, ndisc_snoop.c is now built
conditionally on CONFIG_IPV6=y so that it is easier to handle hostapd
builds with toolchains that do not support IPv6 even if Hotspot 2.0 is
enabled in the build.

It was possible for some of the SAE test cases (e.g., ap_ft_sae) to fail

configuration to a value that is not enabled by default. Fix this by

Some static analyzers had problems understanding "left < count * len"

Previously, this was implicitly limited by the 16-bit length field to
65535. This resulted in unhelpful static analyzer warnings (CID 62868).
Add an explicit (but pretty arbitrary) limit of 50000 bytes to avoid
this. The actual WSC messages are significantly shorter in practice, but
there is no specific protocol limit, so 50000 is as good as any limit to
use here.

This extends the earlier PeerKey station side design to be used on the
AP side as well by passing pointer and already validated length from the
caller rather than parsing the length again from the frame buffer. This
avoids false warnings from static analyzer (CID 62870, CID 62871,
CID 62872).

This was too difficult for some static analyzers (CID 62876). In
addition, the pac_info_len assignment should really have explicitly
validated that there is room for the two octet length field instead of
trusting the following validation step to handle both this and the
actual pac_info_len bounds checking.
