I dropped two patches that were upstreamed:
 - Avoid-local-timestamp-disclosure-in-Date-header.patch
 - Avoid-spellchecking-language-disclosure-in-Content-Language-header.patch

I also dropped a patch from debian/series that we don't apply in Tails
any more:
 - Add-pref-for-whether-to-accept-plaintext-protocols-d.patch
