When config_list() gets NULL as sdi, it must return driver opts.
Some drivers, including zeroplus, don't check sdi and return both
driver opts and device opts.
Now that std_serial_dev_acquisition_stop() has the same signature as
the sr_dev_driver dev_acquisition_stop() callback it is possible to remove
the wrapper functions and use std_serial_dev_acquisition_stop() directly
has the callback function.

All callers of std_serial_dev_acquisition_stop() currently pass the same
callback for the dev_close_fn parameter as the dev_close callback of their
sr_dev_driver struct. Remove the dev_close_fn parameter and invoke the
drivers dev_close() callback directly. This simplifies the API and ensures
consistent behaviour between different drivers.

All callers of std_serial_dev_acquisition_stop() currently pass sdi->conn
for the serial parameter. And the other std_serial helper functions already
require that the conn field of the sr_driver_inst passed to the functions
points to the sr_serial_dev_inst associated with the device.
Modify std_serial_dev_acquisition_stop() to follow the same pattern and
remove the serial parameter. This simplifies the API and ensures consistent
behaviour between different drivers.

Some of the standard helper functions take a log prefix parameter that is
used when printing messages. This log prefix is almost always identical to
the name field in the driver's sr_dev_driver struct. The only exception are
drivers which register multiple sr_dev_driver structs.
Instead of passing the log prefix as a parameter simply use the driver's
name. This simplifies the API, gives consistent behaviour between different
drivers and also makes it easier to identify where the message originates
when a driver registers sr_dev_driver structs.

All drivers with the exception of pce-322a pass their dev_close callback to
std_serial_dev_acquisition_stop(). The pce-322a passes std_serial_dev_close()
which is also called from its dev_close() callback and replicates the other
functionality of its dev_close() callback directly in
std_serial_dev_acquisition_stop().
Refactor this to pass the dev_close callback function directly to
std_serial_dev_acquisition_stop(). This makes sure that the driver is
consistent with other drivers and also removes duplicated code.

Use the new software limit helper functions rather than open-coding their
functionality.
This also fixes the issue that driver the does not reset all the limit
statistics in acquisition_start().

The version field in the norma-dmm driver state struct is initialized, but
never read and the same information is also already available in the
sr_dev_inst struct version field. So remove it to simplify the code.
This allows to get rid of the custom dev_close() callback and just use the
standard std_serial_dev_close() instead.

Some driver scan() functions only ever return a single device. For those it
is possible to slightly simplify the handling of the device list by
creating it on demand when the function returns.
Some drivers also have the following expression:
devices = g_slist_append(devices, sdi);
...
if (!devices)
...
This check will never evaluate to false so it is dropped as well.

A common task during device scan is to add the newly discovered devices to
the instance list of the driver. Currently this is done by each driver on
its own. This patch introduces a new helper function std_scan_complete()
which takes care of this. The function should be called at the end of a
driver's scan() callback before returning the device list.
Doing this with a helper function provides guaranteed consistent behaviour
among drivers and hopefully paves the way to moving more standard
functionality directly into the sigrok core.
Another common task that every driver has to do for each device instance is
to initialize the device's driver field. So this is done in the new helper
function as well.
All drivers that can make use of the new helper are updated.

Some drivers set the device instance list to NULL in their scan() callback.
This means the driver loses all references to any devices contained in that
list and their resources will be leaked. Drivers can't free the devices at
this point either since an application might still use a device on the
list. So the existing devices on the instance list need to remain
unmodified during the scan() callback, even if that means that there will
be duplicates on the instance list. Only an explicit invocation of
sr_dev_clear() by the application is allowed to free the devices on the
instance list and reset the list.
