gary rong c9cdf144d5 graphql, internal/ethapi: support overriding accounts in eth_call ()
* graphql, internal/ethapi: extend eth_call

This PR offers the third option parameter for eth_call API.
Caller can specify a batch of contracts for overriding the
original account metadata(nonce, balance, code, state).
It has a few advantages:

* It's friendly for debugging
* It's can make on-chain contract lighter for getting rid of
  state access functions

* core, internal: address comments

This PR is a more advanced form of the dirty-to-clean cacher (),
where we reuse previous database write batches as datasets to uncache,
saving a dirty-trie-iteration and a dirty-trie-rlp-reencoding per block.

core/state: remove lock ()
The lock in StateDB is useless. It's only held in Copy, but Copy is safe
for concurrent use because all it does is read.

Péter Szilágyi d926bf2c7e trie: cache collapsed tries node, not rlp blobs ()
The current trie memory database/cache that we do pruning on stores
trie nodes as binary rlp encoded blobs, and also stores the node
relationships/references for GC purposes. However, most of the trie
nodes (everything apart from a value node) is in essence just a
collection of references.

This PR switches out the RLP encoded trie blobs with the
collapsed-but-not-serialized trie nodes. This permits most of the
references to be recovered from within the node data structure,
avoiding the need to track them a second time (expensive memory wise).

Felix Lange 9e5f03b6c4 core/state: access trie through Database interface, track errors ()
With this commit, core/state's access to the underlying key/value database is
mediated through an interface. Database errors are tracked in StateDB and
returned by CommitTo or the new Error method.

Motivation for this change: We can remove the light client's duplicated copy of
core/state. The light client now supports node iteration, so tracing and storage
enumeration can work with the light client (not implemented in this commit).

Jeffrey Wilcke 10a57fc3d4 consensus, core/*, params: metropolis preparation refactor
This commit is a preparation for the upcoming metropolis hardfork. It
prepares the state, core and vm packages such that integration with
metropolis becomes less of a hassle.

* Difficulty calculation requires header instead of individual
  parameters
* statedb.StartRecord renamed to statedb.Prepare and added Finalise
  method required by metropolis, which removes unwanted accounts from
  the state (i.e. selfdestruct)
* State keeps record of destructed objects (in addition to dirty
  objects)
* core/vm pre-compiles may now return errors
* core/vm pre-compiles gas check now take the full byte slice as argument
  instead of just the size
* core/vm now keeps several hard-fork instruction tables instead of a
  single instruction table and removes the need for hard-fork checks in
  the instructions
* core/vm contains a empty restruction function which is added in
  preparation of metropolis write-only mode operations
* Adds the bn256 curve
* Adds and sets the metropolis chain config block parameters (2^64-1)

Felix Lange 4047ccad2f trie: add start key to NodeIterator constructors
The 'step' method is split into two parts, 'peek' and 'push'. peek
returns the next state but doesn't make it current.

The end of iteration was previously tracked by setting 'trie' to nil.
End of iteration is now tracked using the 'iteratorEnd' error, which is
slightly cleaner and requires less code.
