At the moment, meson stores the list of installed files
in the build directory, and this list must be kept intact
for uninstallation to work. Add a note about it.
Depending on the installation prefix and destination dreictory,
`sudo` may be unnecessary, so remove it from the command,
but mention that it may be needed.
Cleanup controls instead of inserting new elements with id 0 into the
controls list every time there is an unsupported or invalid PropInfo in
an info_changed node event.
The `impl::servers` list contains all servers, and they are all
destroyed in `impl_clear()`. However, by that time, modules were
not freed previously, so if there were any instances of
*module-protocol-native-tcp* loaded, then the unload() method
of those would call `server_free()` on already freed servers,
resulting in use-after-frees. Fix that by unloading modules
before destroying the servers.

Fixes: f181210b29 ("pulse-server: properly unload modules")
Assume that capture and playback nodes from a device have different
clocks. This enables the adative resampler to match them. A lot of devices
actually have slightly different rates and would work out of the box
with this fix.
Make an exception when the card is configured in the pro audio profile.
Then we force the same clock on all device nodes and avoid resampling
and rate matching. This can still be changed with a session manager
override.
It causes some headsets behave strangely. See pipewire#2391,
pipewire#1853.
The BlueZ issue of AVRCP volume sometimes missing that this worked
around was fixed in recent versions. The issue of some headsets not
sending volume without AVRCP player remains, but it appears this breaks
more headsets than fixes.
Don't try to reconnect or wait for profiles, which cannot be connected
because the adapter doesn't have the counterpart sink/source profile.
E.g. we should not reconnect/wait for HFP HF on remote device, if
we don't have the corresponding HFP AG.
If A2DP remote does not acquire its pending transport within a timeout,
we won't get a write error in a2dp-sink, but instead the transport
becomes idle. Currently, we continue writing to the socket as if
everything was fine, even though the data won't be processed at the
remote end.
Handle this by stopping the node and emitting a node error event.
Pipewire may then restart the node to retry.
If the follower of the adapter emits an error event, the adapter needs
to forward it to upper levels so that they know the node has errored,
and handle the situation.
