include/scsi/libfc.h is currently loaded with common code shared between libfc's sub-modules as well as shared between libfc and fcoe. Previous patches attempted to move out non-common code. This patch creates two files for common libfc routines that will not be shared with fcoe, fnic or any other LLDs.
