The kernel communication code used for HSM and changelog is
entangled. 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.
