Directory restructure.
Includes are now via upb/foo.h. Files specific to the protobuf format are now in upb/pb (the core library is concerned with message definitions, handlers, and byte streams, but knows nothing about any particular serializationf format).

- * upb - a minimalist implementation of protocol buffers.
- *
- * Copyright (c) 2009-2010 Google Inc. See LICENSE for details.
- * Author: Josh Haberman <jhaberman@gmail.com>
- *
- * upb_decoder implements a high performance, streaming decoder for protobuf
- * data that works by implementing upb_src and getting its data from a
- * upb_bytesrc.
- *
- * The decoder does not currently support non-blocking I/O, in the sense that
- * if the bytesrc returns UPB_STATUS_TRYAGAIN it is not possible to resume the
- * decoder when data becomes available again. Support for this could be added,
- * but it would add complexity and perhaps cost efficiency also.
