PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.
Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.
The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

Add a pbss flag to the relevant structures to support starting a PCP and

the new PBSS flag attribute.

NOTE: kqueue has to be closed and re-build after forking. epoll *should*
do the same, but it seems that wpa_supplicant doesn't need it at least.
I have re-worked a little bit of the epoll code (moved into a similar
kqueue function) so it's trivial to requeue epoll if needed in the
future.

When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.
Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

Setting a long off channel wait time for P2P Action frames when
we know we are already on the right channel may cause a delay in
sending the Action frame (because the driver may not be able to
satisfy the request for long wait time until previous off channel
requests are over). This may be crucial for P2P response frames
that must be sent within 100 milliseconds of receiving the request.
Fix this by adjusting P2P Action frame wait times as follows:
1. For GO Negotiation Response frame, shorten the wait time to 100 ms.
This is reasonable because the peer has just sent us the GO
Negotiation Request frame, so it is known to be on the right
channel and is probably ready to send us the GO Negotiation
Confirmation frame without delay.
2. For GO Negotiation Confirmation, P2P Invitation Response, and
Provision Discovery Response frames, there is no need for wait
time at all as this is the last frame in the exchange. So set
the wait time to 50 ms to ensure there is enough time to send the
frame.

Rework the Acct-Session-Id and Acct-Multi-Session-Id implementation to
give better global and temporal uniqueness. Previously, only 32-bits of
the Acct-Session-Id would contain random data, the other 32-bits would
be incremented. Previously, the Acct-Multi-Session-Id would not use
random data. Switch from two u32 variables to a single u64 for the
Acct-Session-Id and Acct-Multi-Session-Id. Do not increment, this serves
no legitimate purpose. Exclusively use os_get_random() to get quality
random numbers, do not use or mix in the time. Inherently take a
dependency on /dev/urandom working properly therefore. Remove the global
Acct-Session-Id and Acct-Multi-Session-Id values that serve no
legitimate purpose.

Number of deployed 80 MHz capable VHT stations that do not support 80+80
and 160 MHz bandwidths seem to misbehave when trying to connect to an AP
that advertises 80+80 or 160 MHz channel bandwidth in the VHT Operation
element. To avoid such issues with deployed devices, modify the design
based on newly proposed IEEE 802.11 standard changes.
This allows poorly implemented VHT 80 MHz stations to connect with the
AP in 80 MHz mode. 80+80 and 160 MHz capable stations need to support
the new workaround mechanism to allow full bandwidth to be used.
However, there are more or less no impacted station with 80+80/160
capability deployed.

The ap_sta_deauth_cb and ap_sta_disassoc_cb eloop timeouts are used to
clear a disconnecting STA from the kernel driver if the STA did not ACK
the Deauthentication/Disassociation frame from the AP within two
seconds. However, it was possible for a STA to not ACK such a frame,
e.g., when the disconnection happened due to hostapd pruning old
associations from other BSSes and the STA was not on the old channel
anymore. If that same STA then started a new authentication/association
with the BSS, the two second timeout could trigger during this new
association and result in the STA entry getting removed from the kernel.
Fix this by canceling these eloop timeouts when receiving an indication
of a new authentication or association.
