    rephist: fix an undeclared type compilation error
    
    In 0.3.4 and later, we declare write_array as:
    extern struct bw_array_t *write_array;
    ...
    typedef struct bw_array_t bw_array_t;
    
    But in 0.2.9, we declare write_array as:
    typedef struct bw_array_t bw_array_t;
    extern bw_array_t *write_array;
    
    And then again in rephist.c:
    typedef struct bw_array_t bw_array_t;
    
    So some compilers fail with a duplicate declaration error.
    
    We backport 684b396ce5, which removes the duplicate declaration.
    And this commit deals with the undeclared type error.
    
    Backports a single line from merge commit 813019cc57.
    
    Fixes bug 30184; not in any released version of Tor.
