Felix Lange d3b751e4d9 trie: remove dependency on ethdb 
This removes the core/types -> leveldb dependency.

Jeffrey Wilcke 445feaeef5 core, core/state, trie: EIP158, reprice & skip empty account write 
This commit implements EIP158 part 1, 2, 3 & 4

1. If an account is empty it's no longer written to the trie. An empty
  account is defined as (balance=0, nonce=0, storage=0, code=0).
2. Delete an empty account if it's touched
3. An empty account is redefined as either non-existent or empty.
4. Zero value calls and zero value suicides no longer consume the 25k
  reation costs.

params: moved core/config to params

Felix Lange 1f1ea18b54 core/state: implement reverts by journaling all changes 
This commit replaces the deep-copy based state revert mechanism with a
linear complexity journal. This commit also hides several internal
StateDB methods to limit the number of ways in which calling code can
use the journal incorrectly.

As usual consultation and bug fixes to the initial implementation were
provided by @karalabe, @obscuren and @Arachnid. Thank you!
