[PATCH 1/3] over: unset sqlite_unicode attribute

[Eric Wong <e@yhbt.net>]

None of the human-readable strings stored in over.sqlite3
require UTF-8.  Message-IDs do not, nor do the compressed
Subject IDs (sid) we use for Subject-based threading.  And the
`ddd' (doc-data-deflated) column is of course binary data.

This frees us of having to use SQL_BLOB for the `ddd', column,
and will open the door for us to use dbh_new for Msgmap, too.
