sd_bus_slot_get_bus() returns the bus object that message slot is
attached to.
sd_bus_slot_get_current_handler(),
sd_bus_slot_get_current_message() and
sd_bus_slot_get_current_userdata() return the current handler,
message and userdata respectively of the bus slot is attached to
if we're currently executing the callback associated with slot.
sd_bus_slot_get_bus() always returns the bus object.
On success, sd_bus_slot_get_current_handler(),
sd_bus_slot_get_current_message() and
sd_bus_slot_get_current_userdata() return the requested object.
On failure, they return NULL.
These APIs are implemented as a shared library, which can be
compiled and linked to with the libsystemd pkg-config(1) file.
