Test format

BlockchainTests Fillers

"invalid" section in transaction replaced with "expectException" similar to the one in BlockHeader overwrite
It is now possible to set expected exception depending on the mining network for a specific transaction
This require test_mineBlocks RPC change in the test protocol and t8ntool response change as well.
The new return on test_mineBlocks is a json

{
   "valid" : true,
   "rejectedTransactions" : [
       {
            "hash" : "0x1122..11",
            "error" ; "Gas Limit reached"
       }
   ]
}

BlockchainTests Filled

If the block test filler had transactions marked "expectException" the filled test would have "transactionSequence" section with transaction order as its imported into state in the current block. if transaction import expected to fail it is marked so with exception. The new section allows clients to check transaction rejection in the blockchain tests. As previously invalid transaction been checked only during the test filling. Invalid transaction do not present in the valid block rlp. Now clients can try importing it on top of the previous block state and make sure the rejection exception is validated.

"transactionSequence" : [
 {
     "rawBytes" : "0xf863802b...4db0d72118",
     "valid" : "false",
     "exception" : "TR_NoFunds"
 },
 {
      "rawBytes" : "0xf863802...b4db0d72118",
     "valid" : "true"
 }
],
