Summary:
An Eo class Elm.Sys_Notify acts as a manager of notification
servers. A manager registers and unregisters notification servers.
Notification servers implement the Elm.Sys_Notify_Interface
which allows to send and close notifications.
Currently, only the DBus server is implemented (legacy code).
Even though there are many changes in the code, there should
be no API nor ABI breaks.
