* Problem: state transition code is duplicated
Closes: #672
Solution:
- move gas refund out from ApplyMessage
- move check into ApplyMessage
- move evm construction into ApplyMessage
- ensure context stack is clean after ApplyMessage return
fix unit tests
undo rename
add underflow check
* improve performance
- don't duplicate params loading
- passing EVMConfig around as pointer
* Problem: deep context stack efficienty is not benchmarked
Closes: #626
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
