Tor 0.3.4.7-rc发布，实现匿名通信的隐私保护工具

Tor 0.3.4.7-rc 已发布，修复了旧的 Tor 版本中的几个小的编译、可移植性和正确性问题。官方表示这个版本是候选版本，如果没有发现严重的错误，预计稳定的 0.3.4 版本将（几乎）与此版本相同。

部分更新如下

• Minor features (bug workaround):

• Compile correctly on systems that provide the C11 stdatomic.h header, but where C11 atomic functions don't actually compile. Closes ticket 26779; workaround for Debian issue 903709.

• Minor features (continuous integration):

• Backport Travis rust distcheck to 0.3.3. Closes ticket 24629.

• Enable macOS builds in our Travis CI configuration. Closes ticket 24629.

• Install libcap-dev and libseccomp2-dev so these optional dependencies get tested on Travis CI. Closes ticket 26560.

• Only post Appveyor IRC notifications when the build fails. Implements ticket 27275.

• Run asciidoc during Travis CI. Implements ticket 27087.

• Use ccache in our Travis CI configuration. Closes ticket 26952.
