Phonenumbers

Build changes:
- C++ geocoding build tools now use readdir, since readdir_r is deprecated.
- Update the protobuf-java dependency used to build the C++ metadata from 2.5.0
to 3.0.0. This is an internal change and does not affect the users of the
library.

Code changes:
- Improve parsing logic to be smarter about national-prefix detection &
stripping based on possible-lengths (IS_POSSIBLE_LOCAL_ONLY and
INVALID_LENGTH). Enables e.g. adding Iran short-codes starting with "096"
without the need to hack IR's national prefix parsing config.
- Logging changes: Don't log client-provided phone numbers.
- Add constants for C++ PhoneNumberUtil enums' max values.
