libcamera uses namespaces to sandbox IPA (Image Processing Algorithm)
modules because they are sometimes proprietary binary blobs. The
RestrictNamespaces option in Wireplumber's systemd service breaks this
sandboxing when libcamera is loaded via the libcamera SPA module, so
cameras requiring an IPA do not work.
This commit removes RestrictNamespaces so that the sandboxing works
again. I've confirmed that after this change wireplumber works with
libcamera with an IPA module.
Resolves#466
This copies the logic of media-session's logind module and allows
the bluez monitor to be active in only one user session at a time.
This is especially useful to avoid interference between the gdm
session and the actual user session, which momentarily both have
wireplumber running when logging in/out.
Fixes#54
These allow running multiple instances of wireplumber with
different config files. The config file is denoted on the service
name, ex: wireplumber@bluetooth loads bluetooth.conf
