commit 7460b9755aa0b9b4a54c5c80e47dfdf8c8fc513a
Author: Alexander Færøy <ahf at torproject.org>

    Remove unused function `is_gzip_supported()`.
    
    This patch removes the unused `is_gzip_supported()` and changes the
    documentation string around the `compress_method_t` enumeration to
    explicitly state that both `ZLIB_METHOD` and `GZIP_METHOD` are both
    always supported.
    
    Zlib version 1.2.0 was released on the 9'th of March, 2003 according to
    their ChangeLog.
