Add symlink method to util.opener.

Differences from os.symlink:

- the symlink name is relative to the opener base directory

- if a file with that name already exists, it's removed

- if necessary, parent directories are created

- if the system (OS or filesystem) doesn't support symlinks, a
  regular file is created.  Its contents are the symlink target.
