fix t8n tool bug and accounts cache bug
t8n: a silly bug contract address generator, should use original
tx nonce instead of read the nonce from sender address in state db.
Although in EVM contract address generated by reading nonce from state db
is correct, outside EVM that nonce value might have been modified,
thus generating incorrect contract address.

accounts cache: when clearing account storage, the originalValue
cache is not cleared, only the storageRoot set to empty storage root,
this will cause getStorage and getCommitedStorage return wrong value
if the originalValue cache contains old value.

EVM state transition tool

The t8n tool is a stateless state transition utility.

Build instructions

There are few options to build t8n tool like any other nimbus tools.

  1. Use nimble to install dependencies and your system Nim compiler(version <= 1.6.0).
    $> nimble install -y --depsOnly
    $> nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
    $> nim c -r -d:release tools/t8n/t8n_test
    
  2. Use nimbus shipped Nim compiler and dependencies.
    $> make update deps
    $> ./env.sh nim c -d:release -d:chronicles_default_output_device=stderr tools/t8n/t8n
    $> ./env.sh nim c -r -d:release tools/t8n/t8n_test
    
  3. Use nimbus makefile.
    $> make update
    $> make t8n
    $> make t8n_test
    

Command line params

Available command line params

Usage:

t8n [OPTIONS]...

The following options are available:

 --trace                 Output full trace logs to files trace-<txIndex>-<txhash>.jsonl [=false].
 --trace.memory          Enable full memory dump in traces [=false].
 --trace.nostack         Disable stack output in traces [=false].
 --trace.returndata      Enable return data output in traces [=false].
 --output.basedir        Specifies where output files are placed. Will be created if it does not exist.
 --output.body           If set, the RLP of the transactions (block body) will be written to this file.
 --output.alloc          Determines where to put the `alloc` of the post-state. [=alloc.json].
                             `stdout` - into the stdout output.
                             `stderr` - into the stderr output.
                             <file>   - into the file <file>.
 --output.result         Determines where to put the `result` (stateroot, txroot etc) of the post-state.
                             [=result.json].
                             `stdout` - into the stdout output.
                             `stderr` - into the stderr output.
                             <file>   - into the file <file>.
 --input.alloc           `stdin` or file name of where to find the prestate alloc to use. [=alloc.json].
 --input.env             `stdin` or file name of where to find the prestate env to use. [=env.json].
 --input.txs             `stdin` or file name of where to find the transactions to apply. If the file
                             extension is '.rlp', then the data is interpreted as an RLP list of signed
                             transactions. The '.rlp' format is identical to the output.body format.
                             [=txs.json].
 --state.reward          Mining reward. Set to -1 to disable [=0].
 --state.chainid         ChainID to use [=1].
 --state.fork            Name of ruleset to use. [=GrayGlacier].
