Log: Add alias support to gpart. When we're creating new providers for each of the partitions, add aliases to the geom before we create the provider so when geom_dev tastes the provider, the aliases are in place so the proper /dev entries are created. So foo5p6 gets created as an alias for bar5p6 when foo is an alias for bar in the geom we're partitioning with g_part. This also copies aliases from the container geom (eg disk) to the label geom (the disk with GPT partitioning) so that aliases nest properly.
