Originally, moving an in-cone <source> to an out-of-cone <destination>
was not possible, mainly because such <destination> is a directory that
is not present in the working tree.
Change the behavior so that we can move an in-cone <source> to
out-of-cone <destination> when --sparse is supplied.
Such <source> can be either clean or dirty, and moving it results in
different behaviors:
A clean move should move the <source> to the <destination>, both in the
working tree and the index, then remove the resulted path from the
working tree, and turn on its CE_SKIP_WORKTREE bit.
A dirty move should move the <source> to the <destination>, both in the
working tree and the index, but should *not* remove the resulted path
from the working tree and should *not* turn on its CE_SKIP_WORKTREE bit.
