Title: National Number Integer Overflow on 32bit systems

PhoneNumberUtil gives wrong output when parsing national numbers larger than 2147483647 ( 2 ^ 31 - 1) on 32 bit systems.

I have attached a test supporting the issue and a possible fix. I'm not sure if the fix introduces new bugs but all the existing tests are passing.
