Make it possible to add a NULL param to the pending list. The NULL
param removes all previous updates.
When applying the updates, the NULL param removes the params from
the target list.
This has two advantages: it actually removes params that become
unreadable or that got removed and it allows us to update the target
list more efficiently in one single loop.
When nothing else was decided, use the client requested access
method. The idea is that pipewire-pulse will detect a flatpak client
an performs the pipewire connection on behalf of the client,
requesting flatpak access restrictions.
In the corked state we simply hand out silence and don't try to
consume data from our ringbuffer.
Also set the corked state before syncing this with the data thread.

Send server change events to subscribers, when default nodes change due
to some nodes being added/removed/changed, also if there is no metadata
change. Make sure the event is consistent with the result from
find_device at the time.
Previously, these were not necessarily sent, or information from
find_device immediately after the event might not reflect the change
yet.
When a sample is playing a cached sample and it disconnects we should
wait until all the pending samples are finished otherwise we stop
their playback and get a chopped or broken sample.
See #595
Assume -EACCES is a normal thing when checking /proc/<pid>/root and
continue with just an info message. Log a warning and assume
flatpak for all other errors.
Fixes#432
Allow only one memblock in the output queue. Otherwise, if the
client is for some reason not reading from the socket, we would queue
an unlimited amount of messages until we get killed by OOM.
Change some warn to debug in the process function for things we
handle from the non-rt thread.
Fixes#488
Pulseaudio unsets the preferred sink/source when stream is moved to a
default target. Emulate this behavior by setting + unsetting
target.node, which informs policy-node to move it accordingly.
PulseAudio starts with underrun_for equal to -1, sets it to 0 when
something was played and increments it from then on with the number
of bytes played.
