See https://www.sqlite.org/vtab.html for more details.
This work was started from
https://github.com/gwenn/gosqlite/blob/master/vtab.{c,go} and adds:
- Porting the API to go-sqlite3 APIs.
- Support for >= Go 1.6 without requiring the `cgocheck` flag to be changed.
- Filling out the unfinished callback functions for the `Vtable` struct.
- A simple `Context` API layer for ease of use when adding modules.
Tests are included.
