Tor 0.3.3.1-alpha resumes allowing RunAsDaemon=1 with relative DataDirectory
And then in 0.3.3.1-alpha we did commit 192be006, which split the original options->DataDirectory into a new DataDirectory_option variable.
But warn_about_relative_paths() continues to look at
n += warn_if_option_path_is_relative("DataDirectory",options->DataDirectory);
and that function is called near the top of options_validate() -- before we call validate_data_directories() which is what populates options->DataDirectory.
