add a few types. export DBTX.

This change includes several enhancements:
1. Add the `blob` type
2. Add the `inet` type and import for the `"net"` package as necessary
3. Fixes the "uses" functions so that they work with array columns
4. Export the `DBTX` interface. The unexported type didn't play well
   with [wire](https://github.com/google/wire) which needs concrete
   types which requires them to be exported. That said, since this
   interface is always the same, maybe there should be a type directly
   exported by sqlc, e.g. `"github.com/kyleconroy/sqlc.DBTX"` instead.
5. Fixes some minor lint issues
