Move WAL-related definitions from dbcommands.h to separate header file.
This makes it easier to write frontend programs that needs to understand the WAL record format of CREATE/DROP DATABASE. dbcommands.h cannot easily be #included in a frontend program, because it pulls in other header files that need backend stuff, but the new dbcommands_xlog.h header file has fewer dependencies.
