Hi,
another iteration of the set adding support for indexing attachment
contents. I believe I've addressed all the review comments from the
previous round [1].

The first patch now contains a simple performance test that runs reindex
on all emails with attachments - twice with no filter, and once with a
trivial /bin/true filter. By placing the test early in the series it is
easy to see that the following patches do not make the filter-less runs
slower.

As for the run with the filter, the test does show that the fork
overhead is susbtantial, especially with larger database sizes. As per
previous discussion I believe the cost is acceptable, since the
alternative (a persistent filter daemon) would be far more complex with
regards to both implementation and administration.
