Daira Hopwood ffd97926a8 Clarify in \crossref{transactions} that the remaining value in a transparent transaction value pool 
is only available to miners as a fee in the case of non-coinbase transactions, and that the remaining
value in the transparent transaction value pool of a coinbase transaction is destroyed.

Daira Hopwood 0ad0d3d57a Clarify that decomposition of scalars for scalar multiplication in the action circuit MUST be canonical, 
unless a non-canonical decomposition can be proven to result in an equivalent statement -- and clarify
for which multiplications the latter case applies.

Daira Hopwood 4821afe9ba Add a clarification in \crossref{txnconsensus} that after Heartwood and before Canopy activation, 
Sapling outputs of a coinbase transaction MUST have note plaintext lead byte equal to 0x01.
This was implied by the existing rule that such outputs MUST decrypt successfully with an
all-zero outgoing viewing key.

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.
