Add database package

[marco6]

This PR moves the prepared package and the implementation of prepared to a dedicated and more generic database package, so that it is possible to add other wrappers that add functionality on the way.

This was part of #180 and was split out so that the PR is smaller, and other functionality can use the right interface even if batching is not merged yet.

This PR does not change functionality and should not affect performance in any way.

Also, there is a small difference from the original version of this code in #180: Wrap method is no longer required for this to work, instead NewPrepared accepts a generic interface and acts as the wrapper itself. If this PR gets in this change will be reflected in #180 as well.
