Add Component Port API

Add Component Port API

To support component-based port API, the functions are added.
When calling aul_component_port_create(), AMD creates a socket.
AMD passes a file descriptor to the caller component.
And then, the component waits for events using the received file descriptor.

Adds:
 - aul_component_port_exist()
 - aul_component_port_create()
 - aul_component_port_destroy()

Requires:

 - https://review.tizen.org/gerrit/#/c/platform/core/appfw/launchpad/+/250199/
