Merge branch 'tizen_2.2' of ssh://review.tizendev.org:29418/framework/appfw/com-core into work

Applying socket activation should be supported by new API or Schema.
The latest com-core supports the inet & ipc socket communication using schema.
To open/connect a socket, user can select inet or ipc using schema.

remote://IPADDR:port
local://SOCKET_FILE_PATH

practical example

remote://192.168.0.1:1234
local:///tmp/.my.socket

So I just discards the systemd socket activation code now.

I think, it should be supported by new socket URI.
such as

systemd://SOCKET_FILE

This new schema should be added to handle the socket activation mode.
