Regression introduced in 3560f3ba2d
MEDIA_SESSION_CONFIG_PATH expects the actual directory while
PIPEWIRE_CONFIG_PATH and the built-in fallback both expect the files to
reside within the SESSION_PREFIX subdirectory.
Fixes#1725
config_dir is the new MEDIA_SESSION_CONFIG_DIR environment variable (if
set), impl.config_dir is that or the fallback, whichever applies.

The link might have been made using the node name/nick/description but
we always want to place the id in the properties to make it easier for
apps to handle the relations between objects.
See #1723
The media session modules need to load config files through
sm_media_session_load_conf() and that must be the same config dir as our
main configuration file's directory.
For buffers on the 'dequeued' list, the busy counter was already
incremented in impl_node_process_input(). So it must be decremented again
when these buffers are removed.
The current code has several issues if a pipewiresrc is stopped and deleted
while a buffer is still in use downstream.
- pw_stream_queue_buffer() is never called for the corresponding
pw_buffer. As a result, the busy counter is never decremented and
pw_stream_dequeue_buffer() of the corresponding pipewire output will
return NULL whenever it encounters this buffer.
- The pipewiresrc does not own the buffer reference unless the buffer is
queued in the source, so calling gst_buffer_unref() unconditionally
causes refcount issues for the buffer.
- buffer_recycle() can race with on_remove_buffer() and
gst_pipewire_src_close(). As a result, buffer_recycle() may access pwsrc
when it was already deleted.
The buffer has its own reference to the pool. So the pool object lock can
be used to ensure that the pwsrc, core and stream remain valid in.
buffer_recycle(). If the 'dispose' function pointer was already cleared,
then on_remove_buffer() has already finished, so abort early.
With the pool lock held, it is save to access the pipewire loop. Now the
loop lock can be used to synchronize with on_remove_buffer(). 'dispose'
must be checked again in case on_remove_buffer() was triggered by something
other than gst_pipewire_src_close().
In on_remove_buffer() unref the buffer if it is queued. Otherwise call
pw_stream_queue_buffer() to ensure that the busy counter is decremented
correctly.
The proxy errors are really from the session manager informing us about
decisions it made (failure to link, etc). The state of the stream is not
really affected by this so just emit the error signal and let the app
decide what to do.
Use this to override the default $PIPEWIRE_CONFIG_DIR/media-session.d
directory. This allows us to have separate configuration directories for
pipewire and media-session.
Make things work then there is no default input device and the default
source is actually the monitor of the default sink.
Also implement lookups of monitor sources with the monitor id as the
name.
Fixes#1691
pause_node() will check the IDLE state of the node and will not
deactivate the node when suspending when it was already IDLE.
Fixes an issue where node.pause-on-idle=false filters would not want to
resume after a suspend.
If we try to fetch a property as some specific type and the parsing
fails, log a warning. This should catch any client bugs where the
properties are set wrongly.
