If a pipewire property has quotes, the DOT graph fails to be generated because
they are not escaped. This patch fixes this by escaping the quotes from a
pipewire property value before adding it to the graph
This changes avoids constantly reallocating the DOT data string every time
someting is added. We now always allocate a DOT data string of size 2048, and
we only reallocate by size * 2 if we need more data.
When the server closes the connection in non-interactive mode, we need
to set the quit flag to avoid going into second mainloop_run() that will
just block forever.

If for some reason the proxy gets destroyed, we make sure to remove
listeners and forget the proxy pointer. We do not however delete the
target_link; we consider the proxy destruction as an error.
If another definitive state occured on the link (got to paused state,
got an error), then that event will be ignored. Else we consider it an
error.
Previously, on new node event, we registered a core sync. Linking was
attempted at core sync done but the node did not yet have time to
register its ports.
Only listen to new ports. This delays the linking attempt to when nodes
have had time to create their ports.
Stop using sync for link creation detection. Instead, listen to link
events.
We still listen to errors, link info events are not enough. For example,
if a link already exists, we only get a proxy error and no link info
event.
Now that we have a create_link_proxies() that looks for our matching
nodes/ports and creates proxies if they exist, implementing --wait is
easy.
We move the call to create_link_proxies() the core done event. If it
finds no potential nodes/ports, we keep running our loop, monitoring
new objects.
Make do_link_ports() only create proxies. Previously it ran the event
loop once per attempted link to detect link creation errors. Rename it
to create_link_proxies() to make things clear.
Created proxies are stored into a list (data->link_targets).
create_link_proxies() returns the number of link proxies created. This
can be zero when the two matching nodes have zero ports.
Refactor main() to use create_link_proxies(), ask for a sync then run
the event loop. It will stop on sync done, and we will have received
all potential link proxy errors.
Cleanup all proxies and listeners at the end of main().
Now that both the expected input and output of the resampler is placed
in the rate_match, rename the 'requested' field in pw_time to 'size'
and update the docs.
See #3750
Now that the resampler input size is set in the io_rate field when we
start we can add it to the pw_time struct as well.
This way we can know the required resampler input without having
to dequeue a buffer. This can be handy when the stream is a driver
and needs to know how much data to accumulate before starting the graph.
See #3750
Try to use `media.name` as the display name for a node
when none of the other keys are found in its properties.
For example, `pw_stream_new_simple()` only sets `media.name`
on the created node object by default.
Only names in the `org.freedesktop.ReserveDevice1` namespace
are interesting for the purposes of device reservation, so
use `arg0namespace` in the dbus match rule to filter out others.
This changes the value declared (3 currently versus 0 following this
patch). I have not seen code checking this version number.

Don't just forward the tag and latency events to the follower but let
the audioconvert aggregate and emit the updated tag/latency event
that is then configured on the follower.
When using the DSP mode of the audioconvert, this results in an
accumulated latency/tag from all the DSP ports instead of just
the last DSP port param update.
Put properties with media. prefix in tags in pw-cat.
The driver and follower signal times are currently the same timestamp
so allow a 0 difference between the driver and follower signal time
to calculate the scheduling delay.
