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.
Currently, among others, the `pipewire-pulse` executable is an
exact copy of the `pipewire` executable. Use meson's
`install_symlink()` to avoid the need for compiling the same thing
multiple times. Also use `custom_target()` so that the aliases
are available in an uninstalled environment.
Do the same for `pw-cat`. The benefit is that all aliases
of `pw-cat` are now available in an uninstalled environment.
This commit increasese the minimum meson version to 0.61.1
as that is needed for `install_symlink()`.
The reason for using 0.61.1 instead of 0.61.0 is the following bug:

The data stride for encoded formats should be 1 and also placed in the
stride in the buffer (not 0). So there is really no difference with the
regular codepath.
FFmpeg integration in pw-cat does not strictly require Compress-Offload;
for example, there could be other nodes in the graph that can handle
compressed audio.

* Decouple FFmpeg integration in pw-cat from the ffmpeg option; if
one wants to use Compress-Offload but not the ffmpeg SPA plugin,
it is then possible to just pass -Dpw-cat-ffmpeg=enabled to meson.
Likewise, this also makes it possible to build the ffmpeg plugin
without extending pw-cat.
* tinycompress does not need to be detected in the root meson.build,
since it is only needed by the alsa plugin.
Dictionaries are by default printed in their insertion order.
This is unergonimic when comparing properties created by different
clients, as they may insert them in different orders.
Add a sequence number to pw_param.
Add param_info to param_update to filter out the params of the latest
sequence number.
This can be used to track params from a certain sequence number. Update
node, port and device.
Add a new seq field in the param-info struct. Users can use this
field to keep track of pending param updates.
Store the latest seq number of the param update in the seq field. Remove
all params that don't match the sequence number because they are too
old. This avoids duplicate old params in pw-dump output.
Rework the pulseaudio manager with this same method.
