Subject: Wrap SQL schemas up so rpki-sql-setup doesn't have to be run in the
 build tree (see #8).  This appears to work properly but needs more testing,
 leaving ticket open for now.

Also cleaned up a few things that should have moved from scripts/ to
buildtools/ a long time ago.

+# This uses the SQL::Translator package (aka "SQL Fairy") to parse
+# a MYSQL schema and diagram the result using GraphViz.
+#
+# SQL::Translator appears to be pretty good at analyzing SQL, but is
+# badly confused about how to format record labels in the "dot"
+# language.  I should send the author a patch, but simplest solution
+# for now is just to whack sqlt-graph's broken output into shape.

+# On FreeBSD, SQL Fairy is /usr/ports/databases/p5-SQL-Translator.
