This CL ensures that:
- All declarations in headers are made in the i18n::phonenumbers namespace.
- All USE flags/macros are prefixed with I18N_PHONENUMBERS_ to avoid name
clashes.
- All the code in base/ is actually used (by deleting unused code).
- Outdated occurrences of USE_GOOGLE_BASE don't exist anymore.
- Logging in PhoneNumberUtil is disabled by default (in production). However it
can be enabled by calling PhoneNumberUtil::SetLogger() as it is now done
during testing.

This is done by adding a USE_BOOST compile time flag that is enabled by default
when the library is compiled with CMake (mainly for external users).
In Chromium, the library will be built without the USE_BOOST compile time flag.
Instead the NO_THREAD_SAFETY flag will have to be provided so that the minimal
non-thread-safe subset of base will be used.
This is possible since libphonenumber is only used from the UI thread in
Chromium.
