add a separate tool for generating hints on Multi-Arch headers

It builds on the core functionality of dedup, but uses a different
database schema. Unlike dedup, it aborts downloading Arch:all packages
early and consumes any other architecture in its entirety instead.

+There is a separate analysis application for detecting multiarch related bugs.
+It has the same requirements as the dedup application. It uses four files:
+
+    multiarchschema.sql
+    multiarchimport.py
+    multiarchanalyze.sql
+    multiarchanalyze.py
+
+With the schema you can initialize a database. The importer allows feeding the
+initial dataset or an updated dataset into the database by collecting data from
+a nearby Debian mirror. It is recommended to apply multiarchanalyze.sql once
+after the initial data import to avoid lots of changes on unused indices. The
+final step is generating the hints by running multiarchanalyze.py. Unless
+issuing ANALYZE, the analysis will be slow.
