A proxy should be usable for reading from an in-band file without encurring a stage switch, just like it is for the output direction. These changes introduce the EVL_CLONE_INPUT, EVL_CLONE_OUTPUT creation flags for a proxy, which can be used in a mutually exclusive manner, or combined in order to have a bidirectional channel to the target file. As a by-product, the output direction gains in-band poll() support. Signed-off-by: Philippe Gerum <rpm@xenomai.org>
