Jeffrey Wilcke 410edf0b1a core: set correct public state for all state transition functions 
Fixed an issue where public state and private state were mixed during
the initial phase of the state transition. This causes severe issues
when creating new contracts (and addresses) and messes up the public
nonce, which, indirectly, has an effect on the contracts that are
created on the public state for both public and private txs.

Chetan Sarva ad9d04d6ba Fix SetPrivate and validation 
* Builds on the fix in c828292fa2c009e2865b1f0d521a080499a234d8;
* SetPrivate() must be called after the tx has been signed and
* just before inserting into txpool.

* Added 37 & 38 as valid V values in validation routine

Jeffrey Wilcke 763f939f47 core, core/vm: dual state & read only EVM 
This commit implements a dual state approach. The dual state approach
separates public and private state by making the core vm environment
context aware.

Although not currently implemented it will need to prohibit value
transfers and it must initialise all transactions from accounts on the
public state. This means that sending transactions increments the
account nonce on the public state and contract addresses are derived
from the public state when initialised by a transaction. For obvious
reasons, contract created by private contracts are still derived from
public state.

This is required in order to have consensus over the public state at all
times as non-private participants would still process the transaction on
the public state even though private payload can not be decrypted. This
means that participants of a private group must do the same in order to
have public consensus. However the creation of the contract and
interaction still occurs on the private state.

It implements support for the following calling model:

S: sender, (X): private, X: public, ->: direction, [ ]: read only mode

1. S -> A -> B
2. S -> (A) -> (B)
3. S -> (A) -> [ B -> C ]

It does not support

1. (S) -> A
2. (S) -> (A)
3. S -> (A) -> B

Implemented "read only" mode for the EVM. Read only mode is checked
during any opcode that could potentially modify the state. If such an
opcode is encountered during "read only", it throws an exception.

The EVM is flagged "read only" when a private contract calls in to
public state.
