/** pruned version of CTransaction: only retains metadata and unspent transaction outputs
 *
 * Serialized format:
 * - VARINT(nVersion)
 * - VARINT(nCode)
 * - unspentness bitvector, for vout[2] and further; least significant byte first
 * - the non-spent CTxOuts (via CTxOutCompressor)
 * - VARINT(nHeight)
 *
 * The nCode value consists of:
 * - bit 1: IsCoinBase()
 * - bit 2: vout[0] is not spent
 * - bit 4: vout[1] is not spent
 * - The higher bits encode N, the number of non-zero bytes in the following bitvector.
 *   - In case both bit 2 and bit 4 are unset, they encode N-1, as there must be at
 *     least one non-spent output).
 *
 * Example: 0104835800816115944e077fe7c803cfa57f29b36bf87c1d358bb85e
