Add -c option to pipewire to select config file. Use this to select
the uninstalled conf file.
Rename conf properties, prefix with context.
Simplify the main daemon now that everything can go in config.
Simplify pipewire-pulse now that we can put everything in config, it's
now virtually the same as pipewire but with a differenct config file.
Parse server addresses as array of strings.
Move the daemon config file loading to a new conf.c file used by
the context to load the configuration. This replaces the module
profiles and some hacks to move properties around.
If there is nothing other specified with $PIPEWIRE_CONFIG_NAME or
a property, the client.conf file is loaded as a fallback.
Update the session manager config file to load the modules via the
config now. Rename the session modules section to another name.
Update pipewire-pulse to also load a specific pulse property file.
This then makes it pssible to assign specific RT priorities for the
pipewire-pulse process.
