The D-Bus implementation of RemoveAllNetworks differs wildly from the
CLI implementation. Let's share the implementations.
This resolves use-after-free bugs I noticed, where we continue to use
the 'wpa_s->current_ssid' wpa_ssid object after freeing it, because we
didn't bother to disconnect from (and set to NULL) current_ssid before
freeing it.

Currently, wpa_config_set(), the function that sets wpa_supplicant
per-network properties, returns 1 when a property it attempts to set is
unchanged. Its global parallel, wpa_config_process_global(), doesn't do
this even though much of the code is very similar. Change this, and
several of the parser functions, to resemble the per-network parser and
setter functions.

When network properties are updated via dbus, wpa_config_set() is used

D-Bus clients can call CreateInterface() once and use the resulting
Interface object to connect multiple times to different networks.
However, if the network interface gets added to a bridge, clients
currently have to remove the Interface object and create a new one.
Improve this by supporting the change of the BridgeIfname property of
an existing Interface object.

in enum wpas_dbus_prop, not in enum wpas_dbus_bss_prop) and what
was originally documented for the interface in dbus.doxygen.

This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.
Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.
User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.
When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

When the P2P management interface is deleted, P2P is then disabled and
global->p2p_init_wpa_s is set to NULL. After that, other interfaces can
still trigger P2P functions (like wpas_p2p_find()) using D-Bus. This
makes wpa_supplicant terminate with SIGSEGV, because it dereferences a
NULL pointer. Fix this by adding proper checks, like it's done with
wpa_cli.

We intentionally don't emit property-changed signals on every property
update -- for "less timing critical" messages we delay up to 5
milliseconds waiting to see if we can batch them together. When the
timer hits, we emit the signal anyway and (potentially) log this
message. This amounts to effectively tracing every property update,
which can be quite excessive.
Lower this to MSGDUMP, so MSG_DEBUG can remain slightly more sane.

The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).
Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.
Only wps_pbc is supported.
This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.
Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

This fixes sending of FindStopped, GroupFormationFailure, and
InvitationReceived signals in the case of separate P2P-Device interface.
This extends the coverage of the earlier commit
745d62322b ("dbus: Redirect P2P request to
the managment device if present") to these three functions that were
missing the redirection.
Some wireless controllers might have separate P2P-Device interface, see
as example result of 'iw dev':
phy#0
Unnamed/non-netdev interface
...
type P2P-device
...
Interface wlp2s0
type managed
...
In this case there is separate 'struct wpa_supplicant' created for this
p2p-dev-* device as result of 'wpa_supplicant_add_iface >
wpas_p2p_add_p2pdev_interface > wpa_supplicant_add_iface'.
This instance of wpa_supplicant is not registered in D-Bus
(wpas_dbus_register_*) since for corresponding P2P device interface flag
'struct wpa_interface > p2p_mgmt' is set.
But this instance is saved in p2p_init_wpa_s and is used for handling
P2P related D-Bus commands. Therefore we should look for D-Bus path in
the parent of p2p_init_wpa_s instance.
Without this change test dbus_p2p_discovery starts failing if we set
support_p2p_device in vm-run.sh.
