There is no need to have separate wpa_printf() and different error
message strings for the unlikely out-of-error messages. Use a helper
function, wpas_dbus_error_no_memory(), to get consistent behavior with a
one-line call.

There is no need to have multiple separate return statements for error
cases in a sequence of operations. In addition, there is not much point
in "converting" boolean return values with "if (!res) return FALSE;
return TRUE;" style constructions.

wpas_dbus_simple_property_getter() cannot be used with NULL
DBUS_TYPE_STRING, so replace that with an empty string to handle the
case of no config_methods parameter in the configuration.

Extend the wpa_cli wps_pin command to support specification of the PIN
expiration time in seconds similarly to hostapd_cli wps_pin command when
using wpa_supplicant for AP mode (including P2P GO).

When in AP mode, wpa_supplicant is now enabling WPS (only Internal
Registrar). WPS.Start() call can be used to initiate WPS negotiation
similarly to how this is done in station mode.

A number of fixes/improvements here:
1) Remove casting of getter/setter function types which allows
us to change the prototypes in the future and not have hard-to-find
runtime segfaults
2) Instead of having the getters create a fake reply message which
then gets its arguments copied into the real reply message, and is
then disposed, just pass message iters around and have them add
their arguments to the message itself
3) For setters, just pass in the message iter positioned at the
start of the argument list, instead of each setter having to skip
over the standard interface+property name
4) Convert error handling to use DBusError and return the error
back down through the call stacks to the function that will
actually send the error back to the caller, instead of having a
fake DBusMessage of type DBUS_MESSAGE_TYPE_ERROR that then
needs to have the error extracted from it.
But most of all, this fixes various segfaults (like rh #725517
and #678625) which were caused by some functions deep down in the
getter callpaths wanting a source DBusMessage* when the getters were
used for two things: signals (which don't have a source DBusMessage)
and methods (which will have a source DBusMessage that's being
replied to). This duality made the code fragile when handling
errors like invalid IEs over the air.

Instead of sending PropertiesChanged signals for each changed
property separately, mark properties as changed and send aggregated
PropertiesChanged signals for each interface in each object.
Aggregated PropertiesChanged signal is sent
- for all object after responding on DBus call
- for specified object after manual call to
wpa_dbus_flush_object_changed_properties() function
- for each object separately after short timeout (currently 5 ms)
which starts when first property in object is marked changed
The perror() calls do not make much sense with libdbus functions and
wpa_printf() would really be used for all error printing anyway. In
addition, many of the error messages on out-of-memory cases are not
really of much use, so they were removed. This is also cleaning up
some of the error path handling to avoid duplicated code.
These cannot be NULL, so there is no point in checking for that. In
addition, the accessor function for this is just making the code harder
to understand.
This was mostly identical code that had been copied for the new D-Bus
API implementation and as such, should really have been shared from
the beginning. In addition, the copied code ended up generating
interesting stack traces since the actual D-Bus connection was being
shared even though the pointer to it was stored in two distinct
data structures. The old D-Bus code ended up dispatching some
D-Bus callbacks which ended up running the new D-Bus code.
Since the private context pointers were mostly identical, everything
seemed to more or less work, but this design was just making things
more complex and potentially very easy to break.
The D-Bus interface does not really have anything to do with the
wpa_supplicant ctrl_iface interface and as such, this prefix in
dbus files is both confusing and unnecessarily. Make the file names
shorter by removing this prefix.
