Adam Spiers 8436768144 Eliminate erroneous warning when unstowing (#65)
When unstowing a package, cleanup_invalid_links() is invoked to remove
any invalid links owned by Stow.  It was invoking link_owned_by_package()
to check whether each existing link is owned by Stow.  This in turn
called find_stowed_path() which since 40a0807185 was not allowing for
the possibility that it could be passed a symlink *not* owned by Stow
with an absolute target and consequently emitting an erroneous warning.

So remove this erroneous warning, and refactor find_stowed_path()
to use two new helper functions for detecting stow directories:
link_dest_within_stow_dir() and find_containing_marked_stow_dir().
Also refactor the logic within each to be simpler and more accurate,
and add more test cases to the corresponding parts of the test suite.

Fixes #65.
Closes #103.
