/**
 * Returns a filesystem instance. The fileystem instance is wired for release at the completion of
 * the current Servlet request via the {@link FileSystemReleaseFilter}.
 * <p>
 * If a do-as user is specified, the current user must be a valid proxyuser, otherwise an
 * <code>AccessControlException</code> will be thrown.
 *
 * @param ugi principal for whom the filesystem instance is.
 *
 * @return a filesystem for the specified user or do-as user.
 *
 * @throws IOException thrown if an IO error occurred. Thrown exceptions are
 * handled by {@link HttpFSExceptionProvider}.
 * @throws FileSystemAccessException thrown if a FileSystemAccess releated error occurred. Thrown
 * exceptions are handled by {@link HttpFSExceptionProvider}.
