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!
