#5481 relocate.cc: Rewrite relocation algorithm.

[Werner LEMBERG]

relocate.cc: Rewrite relocation algorithm.

Following the recently added documentation, this implementation should be
much easier to follow.

This patch also contains the following commits:

• flower/file-name.cc: Better handling of . and .. components.

Update tests.

• running.itely: Document relocation.

Note that the described relocation algorithm doesn't reflect reality; it
will be implemented in a forthcoming commit.

• main.cc, relocate.cc: Minor code clean-up.
