Log Message:
update package to version 2.12.2

It's the successor to amavisd-new both in sources and in versioning,
but strictly speaking it's now "amavis". I kept the package name to
make it easier to update existing installations.

   amavis-2.12.0 release notes

   This software is renamed from amavisd-new to amavis.

   NEW FEATURES

   - Introduce Rspamd client extension
     With this extension, Amavis can use Rspamd either running on the same
     server or remotely. Connections are made using HTTP/HTTPS depending on
     configuration, the latter requiring a HTTPS-capable proxy (like NGINX or
     Apache) for Rspamd, which does not natively support HTTPS. Basic
     authentication with name/password pairs is also available.
     Implemented by Ralph Seichter.
     MR: https://gitlab.com/amavis/amavis/merge_requests/11

   BUG FIXES

   - Treat "not an OLE file" as a successful result
     Amavis supports calling the ripOLE program to extract embedded objects
     from Microsoft OLE documents. However, not all Microsoft documents
     contain said objects, and the underlying file format changes when they
     do. Since Amavis can't tell the difference, it passes everything to
     ripOLE unconditionally.  Amavis now treats the "not an OLE file" error
     code of ripOLE as a successful result, proceeds normally and scans the
     file as a whole.
     Fixed by Michael Orlitzky.

     policy bank to be loaded;
