Introduce the `fmt::dbus` module with a complete D-Bus type-system. This adds the `element` module, as well as the `signature` module. Combined they provide full parsers of D-Bus type strings with support for a range of variants: - `DVariant`: The classic D-Bus wire format as defined by the original dbus-specification, but including extensions up to the current version. - `GVariant`: A complete rework of the wire-format, but type-system compatible with `DVariant`. It is mainly used by the GNOME project and glib. - `Json`: A new `GVariant`-compatible version, but using JSON as encoding. `dbus::Sig` is the main type of the type-system. It represents a D-Bus Single Complete Type, but provides pre-formatted information on the full type and all its sub-types. `dbus::Cursor` is used to iterate over a type and its individual elements. It is only needed when introspecting unknown types. Signed-off-by: David Rheinsberg <david@readahead.eu>
