361082ec4b 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`.

ab16ce70fc core, miner, tests: renamed state methods 
* Update => SyncIntermediate
* Added SyncObjects

SyncIntermediate only updates whatever has changed, but, as a side
effect, requires much more disk space.

SyncObjects will only sync whatever is required for a block and will not
save intermediate state to disk. As drawback this requires more time
when more txs come in.

d8fe64acaa core, miner: added queued write to WriteBlock 
This fixes an issue with the lru cache not being available when calling
WriteBlock. WriteBlock previously always assumed to be called from the
InsertChain where the lru cache was always created prior to calling
WriteBlock. When being called from the worker this could lead in to a
nil pointer exception being thrown and causing database corruption.

d09a6e5421 core, eth, miner: moved nonce management to tx pool. 
Removed the managed tx state from the chain manager to the transaction
pool where it's much easier to keep track of nonces (and manage them).
The transaction pool now also uses the queue and pending txs differently
where queued txs are now moved over to the pending queue (i.e. txs ready
for processing and propagation).

ba295ec6fe Log locally mined blocks, after they are 5-deep in the chain 
This helps determine which blocks are unlikely to end up as uncles

 * Store the 5 most recent locally mined block numbers
 * On every imported block, check if the 5-deep block num is in that store
 * Also confirm that the block is signed with miner's coinbase

Why not just check the coinbase? This log is useful if you're running
multiple miners and want to know if *this* miner is performing well.
