Solution:
- add a benchmark to demonstrate an extremely inefficiency in deep
context stack
* Update x/evm/keeper/benchmark_test.go
* prefix storage is irrelevant
* add comment to state_transition.go

* use stack of contexts to implement snapshot revert
Closes#338
add exception revert test case
verify partial revert
mutate state after the reverted subcall
polish
update comments
name the module after the type name
remove the unnecessary Snapshot in outer layer
and add snapshot unit test
assert context stack is clean after tx processing
cleanups
fix context revert
fix comments
update comments
it's ok to commit in failed case too
