netfs, fscache: Move fs/fscache/* into fs/netfs/

There's a problem with dependencies between netfslib and fscache as each
wants to access some functions of the other.  Deal with this by moving
fs/fscache/* into fs/netfs/ and renaming those files to begin with
"fscache-".

For the moment, the moved files are changed as little as possible and an
fscache module is still built.  A subsequent patch will integrate them.
