Libervia Media is now a Python package instead of files to put in a directory to specify
in settings. The discovery is now automatic, removing the need for settings and enabling
easier installation. Furthermore, it should now work even if the package is zipped.
`libervia_media` can now be specified as a dependency for frontends requiring it.
This is a huge configuration refactoring.
The configuration system now uses Pydantic settings, with better validation, better
support for environment variables and other goodies.
The main config files now use TOML instead of INI, this allow for better handling of
complex types, notably dict.
Plugins, components and frontends can declare their config settings in a class which will
be imported dynamically.
`app.sendPostedEvents` was not handling all events (notably not the window system ones),
resulting in side effects such as the image freezing during A/V calls when the mouse was
not moving for a few seconds.
Instead, `app.processEvents` is now used, even though the documentation discourages its
use: in this context, it should be fine, and it's a simple solution.
This is a series of changes necessary to prepare the implementation of remote control
feature:
- XEP-0166: add a `priority` attribute to `ApplicationData`: this is needed when several
applications are working in a same session, to know which one must be handled first.
Will be used to make Remote Control have precedence over Call content.
- XEP-0166: `_call_plugins` is now async and is not used with `DeferredList` anymore: the
benefit to have methods called in parallels is very low, and it cause a lot of trouble
as we can't predict order. Methods are now called sequentially so workflow can be
predicted.
- XEP-0167: fix `senders` XMPP attribute <=> SDP mapping
- XEP-0234: preflight acceptance key is now `pre-accepted` instead of `file-accepted`, so
the same key can be used with other jingle applications.
- XEP-0167, XEP-0343: move some method to XEP-0167
- XEP-0353: use new `priority` feature to call preflight methods of applications according
to it.
- frontend (webrtc): refactor the sources/sink handling with a more flexible mechanism
based on Pydantic models. It is now possible to have has many Data Channel as necessary,
to have them in addition to A/V streams, to specify manually GStreamer sources and
sinks, etc.
- frontend (webrtc): rework of the pipeline to reduce latency.
- frontend: new `portal_desktop` method. Screenshare portal handling has been moved there,
and RemoteDesktop portal has been added.
- frontend (webrtc): fix `extract_ufrag_pwd` method.

- file send/receive commands now supports webRTC transfer. In `send` command, the
`--webrtc` flags is currenty used to activate it.
- WebRTC related code have been factorized and moved to `libervia.frontends.tools.webrtc*`
modules.

- Moved original UI to a separated class, and use if with the `simple` output
- By default, best output is automatically selected. For now `gui` is selected if possible,
and `simple` is used as fallback.
- The new `tui` output can be used to have the videos directly embedded in the terminal,
either with real videos for compatible terminal emulators, or with Unicode blocks.
- Text contrôls are used for both `simple` and `tui` outputs
- several options can be used with `--oo` (will be documented in next commit).

``call`` commands now handle various output. Beside the original one (now named
``simple``), a new ``gui`` one display a full featured GUI (make with Qt).
PyQt 6 or more needs to be installed.
