[tor-commits] [tor/master] Move smartlist_add_{v, }asprintf into smartlist.[ch]

commit 3883338c8121212b3f6f9c020d489d50bbcdd855
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Fri Jun 22 09:26:19 2018 -0400

    Move smartlist_add_{v,}asprintf into smartlist.[ch]
    
    Now that I know that "strings" nests below "container", I know this
    is safe.
