This is equivalent to the P2P_REMOVE_CLIENT command on control
interface. This can be used to remove the specified client [as object
path or string format interface address] from all groups (operating and
persistent) from the local GO.
Argument(s): peer[object path] OR iface[string format MAC address]

D-Bus used the p2p_dev member in struct wpa_supplicant to track the
interface used for P2P Device operations. However, this is not needed as
the interface used for P2P Device operations is stored in struct
wpa_global->p2p_init_wpa_s.
Replace all the redirections to wpa_s->p2p_dev with redirections to
wpa_s->global->p2p_init_wpa_s and removed this member as it is no
longer needed.

This command is for a specific P2P group, not for the P2P Device
instance and as such, wpa_s pointer must not be replaced with the
interface that is used for P2P Device management.

Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.
Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

The dbus interface documentation says the following about the
WPS property of the fi.w1.wpa_supplicant1.BSS interface:
==
WPS information of the BSS. Empty dictionary indicates no WPS support.
Dictionary entries are:
Type s "pbc", "pin", ""
==
However the implementation returns "type" => "" for BSSes
that do not support WPS.
Fix the implementation to match the documentation.
Return empty dictionary if there is no WPS support.
And "type" => "" if WPS is supported, but is not in progress
right now.

wpa_supplicant_deinit_iface() ends up removing all P2P groups if the
removed interface is the parent interface. This is correct behavior in
general, but this resulted in issues in the new group interface
initialization error path since wpa_s->parent was not assigned before
hitting this check. Fix this by assigning wpa_s->parent as part of
wpa_supplicant_add_iface().

entry->strarray_value was left to point to freed memory in case
os_realloc_array() failed. This resulted in the following
wpa_dbus_dict_entry_clear() trying to free an already freed memory area.
In addition, the separately allocated strings in the array would have
been leaked in such a case. Furthermore, wpa_dbus_dict_entry_clear() was
not prepared for the possibility of the initial os_calloc() call failing
and entry->strarray_value being NULL without array_len being cleared to
zero. That would have resulted in reading uninitialized memory and NULL
pointer dereference.
