Add capture.props and playback.props to configure the created streams
with arbitrary properties.
Improve format parsing, make it possible to have different formats peer
stream.
Improve some of the property handling.
This can now also be used to upload a stream to a snapcast server, add
an example of this to the docs.
Instead of doing (cycle+1) & 1 for output ports, simply swap the io
areas depending on the port direction (0 = input, 1 = output) and
just to cycle&1 for all ports.
Websites like squig.link or https://www.autoeq.app/ generate a file for
parametric equalization for a given target, but this is not a format
that can be directly given to filter chain module.
This module translates the file to filter chain module arguments and
then loads the filter chain module with these arguments.
`registry_event_global()` creates an `object` object for every object,
not just those matching `data::pattern`. However, previously
`registry_event_global_remove()` only destroyed those objects
that matched the given pattern. Fix that by destroying
every object.

Check for NULL when importing a buffer and log a message instead of
trying to deref the NULL pointer and crash.
Add some more logging to mem when importing a bad fd.

When processing the output of pw-mon in real time, it is presently
difficult to know when an event is completed because the last attribute
or property is different for each type of event.
This change corrects that by terminating each event with an empty new line.
All pw_core event handlers (`on_core_*()`) currently receive a pointer
to `struct data`, not `struct proxy_data`; as can be seen from the
`pw_core_add_listener()` call in `main()`.

Both the GPtrArray and its contents are leaked in case of success.
`pw_stream_connect()` copies the params as needed, so use `g_autoptr()`
to free the array and with it, its contents.
When a node does not specify a data-loop class, use the class of the
first data loop. This makes the nodes spread out over the first
(default) data-loop class.
The threadloop might fail to create because of missing plugins, so
handle that.
The context might fail to create because of some fatal config error or
missing plugin, handle that too instead of crashing.
See #3994
Don't spam the warning about kernel missing features required for snap
on every pulseaudio connection, but instead show it only once, as the
situation is not going to improve.
When iterating a pw_array of `T`, the iterator must be of type `T*`.
Otherwise the wrong pointer will be freed.

We handeled "arg1 arg2 ... " before and used to split between spaces to
get the arguments for execvp but that doesn't work so well when there
are arguments with spaces.
Instead use JSON parsing to get the array of arguments. This make it
possible to use [ arg1 arg2 .. ] and quote each arg separately. You
can still use the old method and even double escape:
"\"arg1\" \"arg2 with spaces\"" or
[ "arg1" "arg2 with spaces" ]
Move the bits that are used in the realtime thread away from the bits
from the main thread to avoid bitfield races. Move some fields in rt
structs to make it explicit that they are only to be modified from the
realtime threads.
Change the GenericFd data type to SyncObj. It's probably better to
explicitly state the data type than to make something generic. Otherwise
we would need to transfer the specific fd type somewhere else and there
is no room for that in the buffer and the the metadata is not a good idea
either because it can be modified and corrupted at runtime.
Add the SyncTimeline metadata. This contains 2 points on two timelines
(SyncObj datas in the buffer). The buffer can be accessed when the
acquire_point is signaled on the timeline and when the buffer
can be released, the release_point on the timeline should be signaled.
This should be fine because it's not possible to get to the data-loop
without doing acquire.
The main purpose is to make it possible first for modules to be loaded
before the first thread is started.
Each time someone asks for the support, acquire a new data loop and fill
it in the support.
Tweaks things a little so that acquire can be called with NULL dict, in
which case it will always use the first data loop. To be moved and
spread around loops one needs to explicitly pass a node.loop.name or
node.loop.class around.
This ensures that loading a plugin from the adapters and spa plugin
loaders always get the same loop when nothing or a node.loop.name is
given.
It doesn't quite work when a node.loop.class is given because then the loop
could be different between spa node and pipewire node. To fix this, we
need to improve the node loader code to make sure the same loop is used
everywhere.
Expose the acquire_loop/release_loop functions and use them in the
modules.
Make sure the nodes created from the module use the same data loop as
the module. We need to ensure this because otherwise, the nodes might
be scheduled on different data loops and the invoke or timer logic will
fail.
