LU-5971 llite: reorganize variable and data structures

LU-5971 llite: reorganize variable and data structures

Rename struct ccc_grouplock to ll_grouplock and move the definition
from vvp_internal.h to llite_internal.h.

struct vvp_thread_info is used in the non-VVP parts of llite so rename
it struct ll_thread_info. Rename supporting functions accordingly.

struct ccc_thread_info is used in the VVP parts of llite so rename
it struct vvp_thread_info. Rename supporting functions accordingly.

Remove ccc_global_{init,fini}(), merging their contents into
vvp_global_{init,fini}() and {init,exit}_lustre_lite(). Rename
ccc_inode_fini_* to cl_inode_fini_*.

Move several declarations between llite_internal.h and vvp_internal.h
with the goal of reserving the latter header for functions that
pertain to vvp_{device,object,page,...}.
