without clamping, that would be nicer, less bias.

Henry de Valence 2d2603cf65 Add a CoinbaseData field, replacing Vec<u8>. 
The CoinbaseData field can only be constructed by the transaction parser, so we
can ensure that a coinbase input is always serializable, as CoinbaseData
instances can't be constructed outside of the parser that maintains the data
size invariant.

Henry de Valence 56d7391f6d Add convenience methods to Transaction. 
Because we represent each transaction version as a different variant of the
Transaction enum, we end up in a situation where fields that are common to
different transaction versions are awkward to access, requiring a match
statement with identical match arms.

To fix this, this commit adds the following convenience methods:

* `Transaction::inputs() -> impl Iterator<Item=&TransparentInput>`;
* `Transaction::outputs() -> impl Iterator<Item=&TransparentOutput>`;
* `Transaction::lock_time() -> LockTime`;
* `Transaction::expiry_height() -> Option<ExpiryHeight>`;

The last returns an `Option` because the field is only present in V3 and V4
transactions.

There are some remaining fields that do not get common accessors, because it
probably doesn't make sense to access independently of knowing the transaction
version: `joinsplit_data`, `shielded_data`, `value_balance`.

Henry de Valence 44b299d15c Parse block heights in coinbase transactions. 
BIP34, which is included in Zcash, encodes the block height into each
block by adding it into the unused BitcoinScript field of the block's
coinbase transaction.  However, this is done just by requiring that the
script pushes the block height onto the stack when it executes, and
there are multiple different ways to push data onto the stack in
BitcoinScript.  Also, the genesis block does not include the block
height, by accident.

Because we want to *parse* transactions into an algebraic data type that
encodes their structural properties, rather than allow possibly-invalid
data to float through the internals of our node, we want to extract the
block height upfront and store it separately from the rest of the
coinbase data, which is inert.  So the serialization code now contains
just enough logic to parse BitcoinScript-encoded block heights, and
special-case the encoding of the genesis block.

Elsewhere in the source code, the `LockTime` struct requires that we
must use block heights less than 500,000,000 (above which the number is
interpreted as a unix timestamp, not a height).  To unify invariants, we
ensure that the parsing logic works with block heights up to
500,000,000, even though these are unlikely to ever be used for Zcash.

Henry de Valence 4957567409 Represent coinbase inputs explicitly. 
Coinbase inputs are handled differently from other inputs and have
different consensus rules, so they should be represented differently in
the source code.  This lets us discard extraneous details (for instance,
it's not necessary to maintain the all-zero hash) and specialize logic.
