L2DBUS Shared D-Bus constants
This namespace defines shared D-Bus constants that are typically utilized by related L2DBUS components.
These constants directly correspond to their 'C' D-Bus reference library equivalents and protocol definitions.

Constants
- SERVICE_DBUS

- The SESSION D-bus bus.
- BUS_SYSTEM
- The SYSTEM D-bus bus.

Message Types
- MESSAGE_TYPE_INVALID
- This value is never a valid message type.
- MESSAGE_TYPE_METHOD_CALL
- Message type of a method call message.
- MESSAGE_TYPE_METHOD_RETURN
- Message type of a method return message.
- MESSAGE_TYPE_ERROR
- Message type of an error reply message.
- MESSAGE_TYPE_SIGNAL
- Message type of a signal message.
Message Handler Return Values
- HANDLER_RESULT_HANDLED
- The result to return in a message callback when a message has been handled.
- HANDLER_RESULT_NOT_YET_HANDLED
- The result to return in a message callback when a message cannot be handled.
- HANDLER_RESULT_NEED_MEMORY
- The result to return in a message callback when more memory is needed to process the message.
D-Bus Errors
