Comment:

 There's a bunch of fixes and a bit of a hack to add IRC notifications and
 other such things in my `bug25549` branch. I ended up needed to build
 libevent from git, so I enabled caching of its build directory between
 builds (not sure if this works yet, as caching only happens on successful
 builds). Everything appears to be working, but there's still three tests
 which fail, which I've created new tickets for: `crypto/openssl_version`
 (#25942), `tortls/x509_cert_free` (#25943), and `tortls/context_new`
 (#25944).

 My branch includes @saper's patches, which I've reviewed. Please review my
 additions, thank you!
