This patch does two things: - We now use u32 instead of size_t for the hops and index fields in EnvironmentCoordinate. This means we're limited to an environment nesting level and variable count of 4Gs respectively. - Instead of wrapping it in an Optional, EnvironmentCoordinate now has a custom valid/invalid state using a magic marker value. These two changes reduce the size of Identifier by 16 bytes. :^)
