commit 7460b9755aa0b9b4a54c5c80e47dfdf8c8fc513a Author: Alexander Færøy ahf@torproject.org Date: Mon Apr 17 14:11:35 2017 +0200

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.
