VRSC iguana sapling changes [part 1] 

- already implemented unsigned raw tx creation (thx @artemii235 for mm codebase)
  tested on iguana_utxoduplicates (dpow is still untested)
- todo: bitcoin_sigtxid implement signing for overwintered & sapling
- todo: check bitcoin_verifyvins
- todo: remove debug printouts
