2b916c9fd5 dbus: Fix IEs getter to use wpa_bss_ie_ptr()
The wpa_bss structure's last element is an empty array. The forgotten
code here assumed that the array of IEs was contiguous to the wpa_bss
structure. This is not always the case anymore. Update this missed case
to use the new wpa_bss_ie_ptr() wrapper to send the correct array of IEs
over DBus.

4b96fafcd8 D-Bus: Share 'remove all networks' with CLI
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.

922fa09972 Global parser functions to return 1 when property unchanged
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.

1c58317f56 D-Bus: Allow changing an interface bridge via D-Bus
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.

This reverts commit adf8f45f8a.

It is basically all wrong. The Pmf property did exist, with a signature of

The patch added a duplicate one, with a signature of "u", in violation
of D-Bus specification and to bemusement of tools that are careful
enough:
