[PATCH] BLOCK: Move extern declarations out of fs/*.c into header files [try #6]

Create a new header file, fs/internal.h, for common definitions local to the
sources in the fs/ directory.

Move extern definitions that should be in header files from fs/*.c to
fs/internal.h or other main header files where they span directories.
