img-streamer: introduction of criu-image-streamer
This adds the ability to stream images with criu-image-streamer
The workflow is the following:
1) criu-image-streamer is started, and starts listening on a UNIX
socket.
2) CRIU is started. img_streamer_init() is invoked, which connects to the
socket. During dump/restore operations, instead of using local disk to
open an image file, img_streamer_open() is called to provide a UNIX pipe
that is sent over the UNIX socket.
3) Once the operation is done, img_streamer_finish() is called, and the
UNIX socket is disconnected.
criu-image-streamer can be found at:
