1. pool: Do not populate/use gentx2. …

   This modifies the pool to report the entire partial header via the first
   generation tx field as intended and no longer populates the second
   generation tx field since it does not apply to Decred.
   
   Some of the old ASICs hacked the stake version in there, but that is
   really not something that should have ever been done because the stratum
   "protocol" (which is not actually very well defined) already does not
   individually provide all of the information the Decred header
   needs nor does it provide an official way to extend it.
   
   Further, the Decred header explicitly provides additional space which
   removes the need to create a new coinbase and update the merkle root.
   
   So, in order to address these things, the field that was intended to
   serve for the coinbase (generate transaction) was repurposed to contain
   the serialized partial header for data after the previous block hash in
   the format it is to be hashed.  Therefore, it should be providing the
   entire remaining partial header to ensure that any future modifications
   to the end of the header are available to miners without modification.
   
   Given that the old ASICs no longer work with the network, this takes the
   opportunity to make the change.
