- Update to version 0.5.4+git2.96dc045:
* l/find-best-target: Allow regular filters to be best targets
* linking-utils: fallback to role priority 0 if none is defined

- Update to version 0.5.4:
* Highlights:
- Refactored the role-based linking policy (previously known
also as "endpoints" or "virtual items" policy) to blend in
with the standard desktop policy. It is now possible use
role-based sinks alongside standard desktop audio operations
and they will only be used for streams that have a
"media.role" defined. It is also possible to force streams to
have a media.role, using a setting. Other features include:
blending with smart filters in the graph and allowing
hardware DSP nodes to be also used easily instead of
requiring software loopbacks for all roles. (#610, !649)
* Improvements:
- Filters that are not declared as smart will now behave again
as normal application streams, instead of being treated
sometimes differently (!657)
* Fixes:
- Fixed an issue that would cause WirePlumber to crash at
startup if an empty configuration file was present in one of
the search paths (#671)
- Fixed Bluetooth profile auto-switching when a filter is
permanently linked to the Bluetooth source (!650)
- Fixed an issue in the software-dsp script that would cause
DSP filters to stay around and cause issues after their
device node was destroyed (!651)
- Fixed an issue in the autoswitch-bluetooth-profile script
