* lite2: move AutoClient into Client Most of the users will want auto update feature, so it makes sense to move it into the Client itself, rather than having a separate abstraction (it makes the code cleaner, but introduces an extra thing the user will need to learn). Also, add `FirstTrustedHeight` func to Client to get first trusted height. * fix db store tests * separate examples for auto and manual clients * AutoUpdate tries to update to latest state NOT 1 header at a time * fix errors * lite2: make Logger an option remove SetLogger func * fix lite cmd * lite2: make concurrency assumptions explicit * fixes after my own review * no need for nextHeightFn sequence func will download intermediate headers * correct comment
