cmd/evm, core/vm, test: refactored VM and core * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment.

core, core/state, trie: EIP158, reprice & skip empty account write This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>

core/vm: improved EVM run loop & instruction calling (#3378) The run loop, which previously contained custom opcode executes have been removed and has been simplified to a few checks. Each operation consists of 4 elements: execution function, gas cost function, stack validation function and memory size function. The execution function implements the operation's runtime behaviour, the gas cost function implements the operation gas costs function and greatly depends on the memory and stack, the stack validation function validates the stack and makes sure that enough items can be popped off and pushed on and the memory size function calculates the memory required for the operation and returns it. This commit also allows the EVM to go unmetered. This is helpful for offline operations such as contract calls.

core, core/vm, tests: changed the initialisation behaviour of the EVM The EVM was previously initialised and created for every CALL, CALLCODE, DELEGATECALL and CREATE. This PR changes this behaviour so that the same EVM can be used through the session and beyond as long as the Environment sticks around.

core, core/vm, crypto: fixes for homestead * Removed some strange code that didn't apply state reverting properly * Refactored code setting from vm & state transition to the executioner * Updated tests

}
cmd/evm, core/vm, test: refactored VM and core * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * core/vm: byte code VM moved to jump table instead of switch * Moved `vm.Transfer` to `core` package and changed execution to call `env.Transfer` instead of `core.Transfer` directly. * Byte code VM now shares the same code as the JITVM * Renamed Context to Contract * Changed initialiser of state transition & unexported methods * Removed the Execution object and refactor `Call`, `CallCode` & `Create` in to their own functions instead of being methods. * Removed the hard dep on the state for the VM. The VM now depends on a Database interface returned by the environment. In the process the core now depends less on the statedb by usage of the env * Moved `Log` from package `core/state` to package `core/vm`.
