Make the Log holders package-only.

They're an implementation detail, not an exported public API. It would be nice
if Java allowed for package-plus-subpackage visibility.

I'm tempted to just use a Log class per-package across the board, which would
allow one to omit the import and use Log.log.info() which isn't half bad. It's
certainly better than adding a static Logger field to every single class that
uses logging, which is the "best practice" used by every other Java developer
in the world.
