Add drupal_alter hook to values before geocoding

Thanks for the patch, @beeradb. Looks good, committed.

The patch works, but I had to combine several fields of the entity before geocoding them. The current patch doesn't give you access to the entity object, so I modified the patch to include the entity object so that you can access fields other than the source field.

I created the patch from the 7.x-1.2 version (latest stable at the moment) because that's the version I'm working with.

It also seems like a good idea to have a hook in the geocoder function.

I know nothing about the geocoder() function (or its alter), because I've never used it.

I think the geocoder_geocode_values alter is 'wrong', because if you need the entity, you should make your own virtual encodable field. That's why #2159925: Geocode from virtual fields/entity property instead of just real fields exists.

@_wdm_ You should probably create a new issue for that alter.

It looks to me like the issue was fixed and the wrong status was picked by mistake.
