ReaderImpl now maintains either one or two bytes of lookahead,

depending on the value of the first byte, so that an object's initial
tag is included in the data seen by the ObjectReader. Digests and
signatures can therefore be calculated over objects by their readers
without any risk of ambiguity.

Rewrote the bundle reading and writing code to eliminate copying. Signatures and digests are now calculated on the fly as the data is read or written. This is a little bit tricky in the case of reading because ReaderImpl uses a lookahead byte, so the signature and message digest need to lag one byte behind.

Protocol refactoring. Each bundle now consists of a signed header and zero or more signed batches. There is no overall signature on the bundle, since the bundle's contents may need to be processed before the entire bundle has been read. The protocol does not prevent an adversary from removing batches from a bundle, reordering batches, moving them from one bundle to another, etc. However, since each batch is signed and acknowledged independently, no such guarantees are required. Bundle IDs will go away when the retransmission mechanism is changed.
