Daira Hopwood 2d2508d06c In \crossref{orchardkeycomponents}, do not allow construction of Orchard 
spending keys such that the corresponding internal incoming viewing key is 0
or ⊥. (This was already specified for the external incoming viewing key.)
Similarly in \crossref{orchardfullviewingkeyencoding}, do not consider a
decoded key valid if either its external or internal incoming viewing key
would be 0 or ⊥.

fixes #598

Daira Hopwood e381ded490 \crossref{coinbasetransactions} effectively defined a coinbase transaction as the first 
transaction in a block. This wording was copied from the Bitcoin Developer Reference
(https://developer.bitcoin.org/reference/transactions.html#coinbase-input-the-input-of-the-first-transaction-in-a-block),
but it does not match the implementation in zcashd that was inherited from Bitcoin Core.

Instead, a coinbase transaction should be, and now is, defined as a transaction with a
single null prevout. The specifications of consensus rules have been clarified and adjusted
(without any actual consensus change) to take this into account, as follows:

 * a block MUST have at least one transaction;
 * the first transaction in a block MUST be a coinbase transaction, and subsequent
   transactions MUST NOT be coinbase transactions;
 * a transparent input in a non-coinbase transaction MUST NOT have a null prevout;
 * every non-null prevout MUST point to a unique UTXO in either a preceding block, or a
   *previous* transaction in the same block (this rule was previously not given explicitly
   because it was assumed to be inherited from Bitcoin);
 * the rule that "A coinbase transaction MUST NOT have any transparent inputs with non-null
   prevout fields" is removed as an explicit consensus rule because it is implied by the
   corrected definition of coinbase transaction.

Daira Hopwood 27f5bb1e68 Correct a type error in the usage of Commit^ivk: the output type Commit^ivk.Output includes 0, 
but the type of incoming viewing keys should not include 0 because KA^Orchard.Private does not.
This is now handled by explicitly rejecting 0 as output from Commit^ivk when generating ivk
in \crossref{orchardkeycomponents}.

An encoding of ivk as 0 is also rejected in \crossref{orchardinviewingkeyencoding} when parsing
an incoming viewing key.

The action circuit needed no changes because pk_d already could not be the zero point, and
therefore the 'Diversified address integrity' condition fails when ivk = 0.

Daira Hopwood c33e23e0c2 Delete the consensus rule in \crossref{transactions} that required checking that each intermediate 
Merkle root of the note commitment tree is not ⊥. Checking this rule would have imposed a
significant performance penalty, since intermediate roots do not otherwise need to be computed.
