* discovery: use opaque error type for DnsSdError
This helps to decouple discovery and core by not leaking implementation
details of the zeroconf backend into Error conversion impls in core.
* discovery: map all MDNS/DNS-SD errors to DiscoveryError::DnsSdError
previously, libmdns errors would use a generic conversion
from std::io::Error to core::Error
* discovery: use an opaque type for the handle to the DNS-SD service
* discovery: make features additive
i.e. add with-libmdns instead of using not(with-dns-sd).
The logic is such that enabling with-dns-sd in addition to the default
with-libmdns will still end up using dns-sd, as before.
If only with-libmdns is enabled, that will be the default.
If none of the features is enabled, attempting to build a `Discovery`
will yield an error.
* discovery: add --zeroconf-backend CLI flag
* discovery: Add minimal Avahi zeroconf backend
* bump MSRV to 1.75
required by zbus >= 4
* discovery: ensure that server and dns-sd backend shutdown gracefully
Previously, on drop the the shutdown_tx/close_tx, it wasn't guaranteed
the corresponding tasks would continue to be polled until they actually
completed their shutdown.
Since dns_sd::Service is not Send and non-async, and because libmdns is
non-async, put them on their own threads.
* discovery: use a shared channel for server and zeroconf status messages
* discovery: add Avahi reconnection logic
This deals gracefully with the case where the Avahi daemon is restarted
or not running initially.
* discovery: allow running when compiled without zeroconf backend...
...but exit with an error if there's no way to authenticate
* better error messages for invalid options with no short flag
* Debian stretch packages are now available only from archive.debian.org
* Use rust 1.71 - MIPS target demoted to tier 3 at 1.72

(cherry picked from commit 3c0d998825)
Special thanks to @eladyn for all of their help and suggestions.
* Add all player events to `player_event_handler.rs`
* Move event handler code to `player_event_handler.rs`
* Add session events
* Clean up and de-noise events and event firing
* Added metadata support via a TrackChanged event
* Add `event_handler_example.py`
* Handle invalid track start positions by just starting the track from the beginning
* Add repeat support to `spirc.rs`
* Add `disconnect`, `set_position_ms` and `set_volume` to `spirc.rs`
* Set `PlayStatus` to the correct value when Player is loading to avoid blanking out the controls when `self.play_status` is `LoadingPlay` or `LoadingPause` in `spirc.rs`
* Handle attempts to play local files better by basically ignoring attempts to load them in `handle_remote_update` in `spirc.rs`
* Add an event worker thread that runs async to the main thread(s) but sync to itself to prevent potential data races for event consumers.
* Get rid of (probably harmless) `.unwrap()` in `main.rs`
* Ensure that events are emited in a logical order and at logical times
* Handle invalid and disappearing devices better
* Ignore SpircCommands unless we're active with the exception of ShutDown
Include a systemd.service file to run as a user
This new `systemd.service` file allows running and controlling the service as
an unpriviledged user (generally, as part of a user session).
