fullblocktests: Add several negative tests.

Browse Source 
* Fraudulent transaction due to invalid index
* Transaction with no inputs
* Transaction with no outputs
* Transaction output with negative vlaue
* Transaction output with too large value
* Block with multiple transactions that sum to too large value
* Stakebase script too small and too large
* Input transactions with null outpoints
* Blocks with duplicate tx inputs
