Cookie handling performance improvement
rfc2965 is dead

- It is not enabled by default in python cookielib
- Mozilla rejected implementing it https://bugzilla.mozilla.org/show_bug.cgi?id=208985
- Netscape cookies still rules
- It was superseded by RFC6265 which is the facto protocol formalized
cookies: increase candidate list with dot prefixed domains
fix broken doctests
remove scrapyd doc, as it was moved to its own repo
bind mockserver to 0.0.0.0, to listen on all 127.* range (useful for testing broad crawls)
Add garbage collector to downloader

This fixes a couple of issues:
- reactor callLater leaks when using download delay (test was
  re-enabled)
- downloader slot leaking on broad crawls (slots were created but never
  removed)
