Add parse error codes and API for converting error code to text.

Parse errors is represented as enum type `ParseErrorCode`.
Error texts are optional for user.
Added  `GetParseError_En()` in `error/en.h`, user can localize this file
into other files. User may dynamically change the locale in runtime.
