Comment:

 Ok, so this was quite challenging to backport, because there were a lot of
 little bugs. But I think it is worth it to have working CI.

 Here are the branches I created today:
 * travis-osx-029, which backports:
   * the travis config rewrite
   * macOS support
     * fix a bug where missing macOS dependencies weren't being installed
 (#27090, but backported as a precaution)
   * ccache (#26952)
   * asciidoc (#27087)
   * the distcheck configure options fix (#27088) for consistency
   * It passes Travis:
     * https://travis-ci.org/teor2345/tor/builds/414029807
   * A full matrix is running in Travis:
     * https://travis-ci.org/teor2345/tor/builds/414069609
 * travis-osx-032 backports:
   * the lzma and zstd (macOS only) install from 0.3.1
   * make zstd actually work on macOS (#27090)
   * rust cargo online mode
   * rust cargo offline mode
   * It's running in Travis:
     * https://travis-ci.org/teor2345/tor/builds/414067564
   * A full matrix is running in Travis:
     * https://travis-ci.org/teor2345/tor/builds/414071688

 I'm going to leave Travis to run overnight, and hopefully it's all
 successful in the morning. I expect 0.3.3 to take a little while, and then
 0.3.4 and 0.3.5 should be trivial.
