[tor-commits] [tor/master] Split out buffers and socks tests into separate modules.



commit 7a12cbc03d8fda94c9387a1976ad2ffc30b4b5b7
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Wed Jul 17 17:31:27 2013 -0400

    Split out buffers and socks tests into separate modules.
    
    No other changes were made here.  Keeping everything in
    src/test/test.c was a legacy of back when we had all our unit tests in
    one big file.
    
    Doing this now because I'm adding an ext_or_command test.
