Move the user space bits into the liblustreapi. This will also help for a possible relicensing. The kernel portion is also moved from libcfs to obdclass. The original libcfs_kernelcomm.h header is split into three parts: * lustre_kernelcomm.h, a new header for the kernel parts; * uapi_kernelcomm.h, a new header for the data structures shared between userspace and kernelspace; * lustreapi_internal.h receives the private liblustreapi prototypes. The original code in kernel_user_comm.c is split into two parts: * obdclass/kernelcomm.c for the kernel part. filp_user_write() was moved there, and linux-fs.c deleted; * liblustreapi_kernelconn.c for the user part. The calls to CDEBUG have been removed, and calls to CERROR have been transformed to llapi_err_noerrno. The type lustre_kernelcomm has been removed and replace by struct lustre_kernelcomm. Various names and filenames have been harmonized to *kernelcomm*. The unused symbol KUC_FL_BLOCK has been removed.
