Extract extensions into crates

Previously, this repository contained one crate with all extension
definitions and the backend implementation.  This is problematic if
semantic versioning is used as a breaking change in the backend or in a
single extension would also affect all users of any other extension.

This patch moves the extensions into separate crates that can be
versioned independently so that clients only have to depend on the
extension crates they really need.

Fixes: #3
