demandimport: support lazy loading for absolute_import

Before, we didn't support lazy loading if absolute_import was in
effect and a fromlist was used. This meant that "from . import X"
wasn't lazy and performance could suffer as a result.

With this patch, we now support lazy loading for this scenario.
As part of developing this, I discovered issues when module names
are defined. Since the enforced import style only allows
"from X import Y" or "from .X import Y" in very few scenarios
when absolute_import is enabled - scenarios where Y is not a
module and thus there is nothing to lazy load - I decided to drop
support for this case instead of chasing down the errors. I don't
think much harm will come from this. But I'd like to take another
look once all modules are using absolute_import and I can see the
full extent of what is using names in absolute_import mode.
