[tor-commits] [tor/master] Rename `zlib_state` to `compress_state` in `dir_connection_t`.



commit 4b9349192d4bd2e9c598b13d74bc826c8f16d40e
Author: Alexander Færøy <ahf@xxxxxxxxxxxxxx>
Date:   Tue Apr 18 01:10:25 2017 +0200

    Rename `zlib_state` to `compress_state` in `dir_connection_t`.
    
    This patch renames the `zlib_state` field in `dir_connection_t` to
    `compress_state`.
