Subject: [PATCH] test: add database routines for testing

Initially, provide a way to create "stub" messages in the notmuch
database without corresponding files.  This is essentially cut and
paste from lib/database.cc. This is a seperate file since we don't
want to export these symbols from libnotmuch or bloat the library with
non-exported code.
