The standard python `os.makedirs` is insufficient for our
needs: it will only create directories, and ignores the fact
that some path components may be symbolic links.
:param src: The source path in the host file system for which
leading components should be created, or the path
to an sos_* virtual directory inside the archive.
Host paths must be absolute (initial '/'), and
sos_* directory paths must be a path relative to
the root of the archive.
:param mode: An optional mode to be used when creating path
components.
:returns: A rewritten destination path in the case that one
or more symbolic links in intermediate components
of the path have altered the path destination.

S |S ) a4 Check a new destination path in the archive.
Since it is possible for multiple plugins to collect the same
paths, and since plugins can now run concurrently, it is possible
for two threads to race in archive methods: historically the
archive class only needed to test for the actual presence of a
path, since it was impossible for another `Archive` client to
enter the class while another method invocation was being
dispatched.
Deal with this by implementing a locking scheme for operations
that modify the path structure of the archive, and by testing
explicitly for conflicts with any existing content at the
specified destination path.
It is not an error to attempt to create a path that already
exists in the archive so long as the type of the object to be
added matches the type of object already found at the path.
It is an error to attempt to re-create an existing path with
a different path type (for example, creating a symbolic link
at a path already occupied by a regular file).
:param src: the source path to be copied to the archive
:param path_type: the type of object to be copied
:param dest: an optional destination path
:param force: force file creation even if the path exists
:returns: An absolute destination path if the path should be
copied now or `None` otherwise

If encryption fails for any reason, it should be logged by sos but not
cause execution to stop. The assumption is that the unencrypted archive
would still be of use to the user, and/or that the end user has another
means of securing the archive.
Returns the name of the encrypted archive, or raises an exception to
signal that encryption failed and the unencrypted archive name should
