For now, useful for sending custom commands to devices. Using this from
the command line might look something like:
```sh
$ pw-cli send-command <device-id> VolumeControl '{"volumeUp": <route-id>}'
```
Commit b1b565339 ("sendspin: negotiate the first raw format") says that
FLAC and Opus are not supported yet. The receiver also only advertises
PCM formats in its player support.
Reject non-PCM stream/start codecs in the receiver. Otherwise
parse_player() accepts FLAC or Opus without setting client->stride,
while the receive path later uses client->stride as a raw frame size.

Because our midi messages already have a size, we don't need the 0xf0
continuation terminator. Also having the terminator optionally requires
you to check and strip it if it's there.
The easiest algorithm is to check the first byte for start (0xf0) or
continuation (0xf7) and the last byte for end (0xf7) and that should be
enough to process the messages without having to ever stip the last
byte.
Retrieve the connecting client's supplementary group list via
SO_PEERGROUPS and store it as the "pipewire.sec.gids" property.
This allows access-control policies in wireplumber to match on
all groups and not just the primary.
A passive port is not automatically activated anymore by an active peer
node, it now needs the "follow" mode to follow the state of the peer without
activating it.
Keep the flag dont_inhibit_auto_suspend around and use it do decide when
to send suspend messages to the client.
We don't always want to send suspend messages when the stream state changes
because that could happen because the stream was, for example, relinked.
The intention of the suspend message is mostly for monitor streams that
use the dont-inhibit flag and want to follow the suspend state of the
sink.
See #5273
Keep the last relation between the sequence number and the timestamp
(ringbuffer position).
When a retransmission is requested for a given sequence number use the
relation to calculate the corresponding timestamp and retransmit the
packet from the ringbuffer again.
See #5276
The close in the error path will never be called because the fd has been
stolen and will be -1.
Also make sure that when we free the source that we set it to NULL or
else the destroy function will try to free it again.
Make a new library.filter-path for the filter-graph that will filter and
restrict the dlopen filenames (used for the LADSPA plugin only).
By default this is false and so filter-chain can load from absolute
paths without extra checks.
Enable the extra checks for the pulse LADSPA modules and the
audioconvert filter graphs because these allow loading LADSPA plugins
into other processes.
Fixes#5222
There could have been a write error or allocation error while building
the json file that we can detect in spa_json_builder_close().
Error out instead of silently using a truncated JSON.
Use spa_autofree for the memory to make cleanup easier.
Make the module valid_args a structure that includes the argument key,
description and some flags. Use this to enforce mandatory properties
in a more central place.
We should be able to generate the module usage from this as wel later to
have things a bit more structured.
Make pw_net_get_ip also accept NULL ip to just get the port and ip
version. Make rtsp-client use pw_net_get_ip.
Make sure we initialize the iovec before logging in all cases.
