[PATCH] IB/ipath: namespace cleanup: replace ips with ipath 

Remove ips namespace from infinipath drivers.  This renames ips_common.h to
ipath_common.h.  Definitions, data structures, etc.  that were not used by
kernel modules have moved to user-only headers.  All names including ips have
been renamed to ipath.  Some names have had an ipath prefix added.
