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.

Jeffrey Wilcke 64af2aafda core, core/vm: added gas price variance table 
This implements 1b & 1c of EIP150 by adding a new GasTable which must be
returned from the RuleSet config method. This table is used to determine
the gas prices for the current epoch.

Please note that when the CreateBySuicide gas price is set it is assumed
that we're in the new epoch phase.

In addition this PR will serve as temporary basis while refactorisation
in being done in the EVM64 PR, which will substentially overhaul the gas
price code.

Jeffrey Wilcke f0cbebb19f core: added basic chain configuration 
Added chain configuration options and write out during genesis database
insertion. If no "config" was found, nothing is written to the database.

Configurations are written on a per genesis base. This means
that any chain (which is identified by it's genesis hash) can have their
own chain settings.

Jeffrey Wilcke 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.
