Daira Hopwood 5fa8a60b08 Specify (as a note in \crossref{actionstatement}) the encoding of primary inputs to the action circuit. 
This uses new helper functions $\Selectx$ and $\Selecty$ defined in \crossref{concreteextractorpallas}.
The specification of Extract_P has also been refactored to use $\Selectx$ (this does not change the Orchard protocol).

Daira Hopwood 1b5786ea38 Leave it unspecified whether MSG_TXV5 is used for v6 and later transactions. 
The previous wording could have been misinterpreted to require not using MSG_TXV5 for these,
and was partly redundant. Also mention in Motivation that the format of serialized
v5 transactions is not consensus-critical.
