[tor-commits] [tor/master] Fix some compilation warnings in {test_, }hs_descriptor.c

[nickm@xxxxxxxxxxxxxx]

commit 236e1f31d9bb6494fdc700f49739fe381d10bed6
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Mon Mar 13 22:36:47 2017 -0400

    Fix some compilation warnings in {test_,}hs_descriptor.c
    
    Nothing big: just some const char[]s that should have been static,
    and some integer truncation warnings.
    
    Warnings not in any released Tor.
