target: reshuffle headers
Create a new headers, drivers/target/target_core_internal.h that is supposed to hold all target_core-internal prototypes. Move all non-exported includes from include/target to it, and merge the smaller prototype-only includes inside drivers/target into it as well. Mark functions that were found to not be called outside their implementation file static. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
