sashiko & pre-existing bugs

[Roman Gushchin]

Hello,

as some of you might notice, a couple of days ago sashiko stopped to
report preexisting bugs together with not-yet-introduced new issues.
Instead, it started putting them into the database. All M: and R: in the
current MAINTAINERS file have full access to corresponding bugs.

There is a new "Bugs" button in the top right corner which is the access
to the database. You don't need to create an account, invent a password,
etc. It's all stateless.

If you're working on other tools which discover linux kernel issues
and/or can generate reproducers/fix candidates and want to collaborate,
please, reach out to me.

Thanks
