Add chainstate obfuscation to avoid spurious antivirus detection
Adds an `obfuscate` parameter to `CLevelDBWrapper` and makes use of it for all new chainstate stores built via `CCoinsViewDB`. Also adds an `Xor` method to `CDataStream`. Thanks to @sipa @laanwj @pstratem @dexX7 @KyrosKrane @gmaxwell.
