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`.

f7a71996fb core, event/filter, xeth: refactored filter system
Moved the filtering system from `event` to `eth/filters` package and
removed the `core.Filter` object. The `filters.Filter` object now
requires a `common.Database` rather than a `eth.Backend` and invokes the
`core.GetBlockByX` directly rather than thru a "manager".

a6cc02f68f core: deadlock in chainmanager after posting RemovedTransactionEvent
This PR solves an issue with the chain manager posting a
`RemovedTransactionEvent`, the tx pool will try to
acquire the chainmanager lock which has previously been locked prior to
posting `RemovedTransactionEvent`. This results in a deadlock in the
core.

b4374436f3 p2p/discover: fix race involving the seed node iterator
nodeDB.querySeeds was not safe for concurrent use but could be called
concurrenty on multiple goroutines in the following case:

- the table was empty
- a timed refresh started
- a lookup was started and initiated refresh

These conditions are unlikely to coincide during normal use, but are
much more likely to occur all at once when the user's machine just woke
from sleep. The root cause of the issue is that querySeeds reused the
same leveldb iterator until it was exhausted.

This commit moves the refresh scheduling logic into its own goroutine
(so only one refresh is ever active) and changes querySeeds to not use
a persistent iterator. The seed node selection is now more random and
ignores nodes that have not been contacted in the last 5 days.

b9359981f4 xeth: fixed nil pointer of filter retrieval
This fix addresses an issue with filters that were (possibly) not yet
added to the filter queues but were expected. I've added additional nil
checks making sure it doesn't crash and swapped the installation of the
filter around so it's installed before use.

Closes #1665

90cd8ae9f2 rpc/api: don't crash for unknown blocks
Most eth RPC calls that work with blocks crashed when the block was not
found because they called Hash on a nil block. This is a regression
introduced in cdc2662c40 (#1779).

While here, remove the insane conversions in get*CountBy*. There is no
need to construct a complete BlockRes and converting
int->int64->*big.Int->[]byte->hexnum->string to format the length of a
slice as hex.

70b6174748 cmd/geth, core: make "geth blocktest" work again
The test genesis block was not written properly, block insertion failed
immediately.

While here, fix the panic when shutting down "geth blocktest" with
Ctrl+C. The signal handler is now installed automatically, causing
ethereum.Stop to crash because everything is already stopped.

eaa4473dbd core, core/types: readd transactions after chain re-org
Added a `Difference` method to `types.Transactions` which sets the
receiver to the difference of a to b (NOTE: not a **and** b).

Transaction pool subscribes to RemovedTransactionEvent adding back to
those potential missing from the chain.

When a chain re-org occurs remove any transactions that were removed
from the canonical chain during the re-org as well as the receipts that
were generated in the process.

Closes #1746

b60a27627b core: transaction nonce recovery fix
When the transaction state recovery kicked in it assigned the last

the same nonce to occur.
