We did not handle quoted-printable because mime package handles it.

Support the new scheme of associating fixing commits with bugs.
Now we provide a tag along the lines of:
Reported-by: <syzbot+a4a91f6fc35e102@syzkaller.appspotmail.com>
The tag is supposed to be added to the commit.
Then we parse commit logs and extract these tags.
The final part on the dashboard is not ready yet,
but syz-ci should already parse and send the tags.
1. Allows sending emails upstream.
2. Filter out duplicate emails coming from our mailing lists.
3. Increase retry attempts for email commands
(don't want them to fail due to concurrent crash reports from managers).
- save Message-ID and use In-Reply-To in subsequent messages
- remember additional CC entries added manually
- don't mail to maintainers if maintainers list is empty
- improve mail formatting and add a footer
- implement upstream/fix/dup/invalid commands over email
- add tests
