When in passthrough mode, use the position io to update the
io_rate_match fields for the follower. This makes it possible for the
follower to also provide the right amount of data when the converter
is not selected in passthrough.
Add an option to configure the converter in None port config where it
removes all the ports. We can use this when removing the converter to
make sure all it's ports are removed.
When we remove the converter, make sure we expose the follower ports
directly so we can use them for passthrough.
That was found by GCC fanalyze pass. Fixes warning:

Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
When setting the Latency parameter on one side of the converter, set
it also on the other size. We should actually implement propagating
the latency through all the elements of the converter later.
Implement latency handling on fmtconvert.
merger and splitter change latency on all ports when on port changes.
All this makes the configured and exposed latencies visible on all
ports from adapter.
Always set the HAVE_OUTPUT flag because we always consume the
input and produce output, either to a buffer or an error.
This makes sure processing never stalls when something is wrong
on the output side.
See #1305
Follow the rate of the _io_position area and adjust the resampler
to match. This ensures that we always process at the DSP samplerate
to the target negotiated fixed rate of the device/stream.
The merger and splitter use the samplerate from the _io_position
for the DSP formats so set the samplerate to 0 to make sure we
don't use it to negotiate a format with the peer.
Implement a port recalculate latency method that takes the min
and max latency of all peer ports and sets that as the new port
latency.
When a link is made, let the output and input port recalculate
latencies.
Pass latency param in audioconvert.
When we add a new listener to an object, it will emit the full state
of the object. For this it temporarily sets the change_mask to all
changes. Restore the previous state after this or else we might not
emit the right change_mask for the next listener.
Consider the case where one there are two listeners on an object.
The object emits a change and the first listener wants to enumerate the
changed params. For this is adds a new listener and then triggers the
enumeration. If we set the change_mask to 0 after adding the listener,
the second listener would get a 0 change_mask and fail to update
its state.
This replaces the manual check for "true" and some (inconsistent) return value
of atoi. All those instances now require either "true" or "1" to parse as
true, any other value (including NULL) is boolean false.
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).
When we have a soft Mute or Volume, use the soft volume.
When we get a volume update with only a channel Mute/Volume, use
the channel volumes.
