Join a READY listener MRP attribute when we recveive the transmit
response.
Also listen for talker attributes.
Remove attribute callbacks, we don't need them because we moved the
packet construction in the MRP users.
Implement notify for listener attributes.
A connect will now make my MOTU send samples to PipeWire.
Remove some of the json parsing for now, work with descriptors.
Remove some parsing code.
Implement GET_AVB_INFO.
Keep descriptors in a list.
Add some utils.
Listen to all messages. We don't seem to receive TSN messages from our
local host it seems.
Reply with not-implemented for an AEM_COMMANDS.
Implement some mode ADP messages.
The default metadata update may be delayed for some time after
SET_DEFAULT, since the session manager has to work on it.
MOVE_* commands need to know what the client thinks is the current
default sink, so that they can decide between "move to default" and
"move to specific device".
To avoid race condition here, stash the default value set by the client
and use it in the MOVE_* commands, until the metadata update arrives.
When we end up in a case where we are running 0 handles, such as when we
have a stereo filter but we want mono output, emit an error until we can
reasonably handle this case.
`client_update_quirks()` may modify `client::props` depending
on the "pulse.rules" section defined in the configuration file,
which means that it can change the value corresponding to the
"application.name" key. Therefore, `client::name` needs to
be queried after that.
`client::name` points to a string that is owned by `client::props`,
so when the property list is updated, it needs to be refreshed as well.
Otherwise, various use-after-frees can be triggered, for example:

Add some 'before' debug info of the attributes.
First clamp the fragsize to the maxlength and then clamp to the
minfrag or else we could bypass the configured minfrag by setting a
lower maxlength.
Scale the maxlength to at least twice the fragsize so that we can
buffer enough data in the ringbuffer to serve fragsize bytes.
See #2447
As Coverity points out, `ensure_size()` is not fully correct.
Let us assume that the message already has some allocated storage,
and the `realloc()` call in the next `ensure_size()` invocation fails.
In that case `message::data` is freed, but the pointer is left behind.
If another `ensure_size()` call is made, then `realloc()` will be called
(since the previous call left `message::allocated` as zero), but the
first argument of the `realloc()` call will be a dangling pointer.
In order to avoid the above, first of all, clear `message::data` after
a failed `realloc()` call, and immediately return `-ENOMEM` if
`message::length` is greater than `message::allocated` since
that signals if the message has even run into an out-of-memory
situation.
Store a pointer to the owner `impl` object instead of
the (embedded) `stat` object. This way `message_free()`
can be simplified since the owner `impl` does not need
to be passed explicitly.
