We want to have buffered images to speed up dump and, slightly, restore. Right now we use plan file descriptors to write and read images to/from. Making them buffered cannot be gracefully done on plain fds, so introduce a new class. This will also help if (when?) we will want to do more complex changes with images, e.g. store them all in one file or send them directly to the network. For now the cr_img just contains one int _fd variable. This patch chages the prototype of open_image() to return struct cr_img *, pb_(read|write)* to accept one and fixes the compilation of the rest of the code :) Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Acked-by: Cyrill Gorcunov <gorcunov@openvz.org>
