Metadata changes:
-- Drops the "-1" that was erroneously included in possible lengths before (didn't break anything, but was wrong) - it was a possibleLength of a sub-component so got added to the generalDesc possibleLengths
-- possibleNumberPattern no longer inherited: we don't use this anyway, we will do another CL soon to stop including it at all in the generated metadata
-- exampleNumber is no longer set on fixed-line and mobile elements from the generalDesc

XML file changes:
-- Stopped specifying "NA" and "-1" specifically for fixed-line and mobile blocks; now they are treated as every other type of phone number: if missing, don't fill them in from generalDesc, but leave them missing.

Code changes:
-- Stop using the exampleNumber on generalDesc for non-geo entities, but look at their phonenumber descs - the exampleNumber won't be stored on the generalDesc anymore. This affects porters if they either copied our build logic or used our built metadata in some way; they should update this method in their port too.

* Porting code to use the new possible length information for calculating
whether a phone number is possible, too short etc.

Making function IsNumberGeographical public. This function operates on
the type of number and the country it belongs to only, so may have some
false positives.

Using this in the geocoder so that geocoding now limited to numbers that
we consider geographical, based on their type and country, rather than
just based on their type. The C++ geocoder did not previously check the
number type/country at all.

Indonesian and Chinese mobile numbers have now been added to the list of
possibly-geographical numbers.

* New useful getExampleNumber methods (for testing) - one for invalid
  numbers and one for getting a number of a particular type without
  specifying a country.

They generated static initializers on Clang/Mac.

This also adds the previously missing <algorithm> include in unicodetext.cc
causing a compilation error on VS2013.

This is a squash of (very slightly modified) patches contributed by thakis@ and

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- Outdated occurrences of USE_GOOGLE_BASE don't exist anymore.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 will be needed to make libphonenumber depend on its own base/ rather than
Chromium's one as it is the case currently.

This CL also fixes the issue reported by Aaron about the logger being invoked
before it is initialized.
