image removal: refactor part 2

Continue the refactoring of image removal.  I didn't manage to break all
the following changes into smaller and easier to digest commits due to
time constraints:

 * Return an error slice instead of a single error. Use multierror only
   in the client/frontend.  Reflect that in the types.

 * Use the batch image removal in the client while preserving the more
   rest-idiomatic single-image removal endpoint.

 * Add a new handler for the single-image removal endpoint to make it
   share the same code as the batch endpoint.

 * Expose bindings for the single and batch endpoints, so we can
   properly test them.

 * Add several convenience functions for error handling to
   pkg/errorhandling.

 * Set the correct error type in libpod to set the exit code to 2 when
   one or more containers are using an image.

 * Massage the bindings tests a bit and tackle compilation errors.
