* The database needs a trigger to get rid of self-references to
...
prevent a foreign key constraint violation on the Refs table when
deleting a path.

* Put the derivation outputs in the database. This is useful for the
...
garbage collector.

* Foreign key support in SQLite is not a persistent setting, so enable
...
it at startup.
* Implement negative caching. Now `make check' passes.

* Add the deriver to the ValidPaths table. In principle we could now
...
store all the derivers of a path efficiently. But that opens a big
can of worms with respect to garbage collector semantics.

* Assign an integer id to every row in the ValidPaths table in order
...
to make the Refs table more space-efficient. For instance, this
reduces the size of the database on my laptop from 93 MiB to 18
MiB. (It was 72 MiB with the old schema on an ext3 disk with a 1
KiB block size.)
