Subject: Minimal libcloudproviders support #7209

- Add it as an optional dependency for linux builds,
  controlled by WITH_LIBCLOUDPROVIDERS, which is enabled automatically
  if the dependencies are available. Note that >=0.3.0 is required.

- Add code to export sync folders through the library and to add a
  minimal "Settings..." menu action.

- Set up cloud provider registration by installing a file into a
  path like /usr/share/cloud-providers/.

- DBus name and path are derived from APPLICATION_REV_DOMAIN by default
  and may be overridden with APPLICATION_CLOUDPROVIDERS_DBUS_NAME and
  APPLICATION_CLOUDPROVIDERS_DBUS_PATH if necessary.
