*   It was confusing and unnecessary. Not every country that has short numbers beginning with a 0 had it, and it is not the only digit that could overlap with a national prefix and hence be interpreted incorrectly.

* Metadata updates for release 8.5.1

* Update release_notes.txt

* Metadata updates for release 8.5.0

* Corrected release notes as US geocding update is mentioned as new addition.

Alternate metadata and test metadata for C++ was regenerated not due to changes in this commit, but due to PR #1726 and that they should have been updated then.

* Metadata updates for release 8.4.1

* Update release_notes.txt

Update doc references to refer to CLDR and the page of CLDR codes where
appropriate - it used to say ISO country codes were used, but they aren't.

Also updated to refer to two *or three* letter language codes since they may be three letters (we use the shortest defined one for a language)

Updating comments about leadingDigits field at territory level as well.

* Metadata updates for release 8.2.0

* Update release_notes.txt

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.

Code changes:

* Phonemetadata.java has two more fields to represent possible lengths of phone numbers. Changed BuildMetadataFromXml (and the resultant jar) to alter the way that metadata about possible-lengths information is consumed when constructing metadata to populate these. Discussion list email: https://groups.google.com/forum/#!topic/libphonenumber-discuss/75TOpTFVi08

Metadata changes:

* Updated phone metadata for region code(s): AG, AM, AX, BY, CD, FI, IN, KR, MA, NA, NL, PK, SY
* Updated short number metadata for region code(s): BR, GB, NL, NZ
* New geocoding data for country calling code(s): 82 (pl, pt, ro, ru, sl, sr, uk, vi)
* Updated carrier data for country calling code(s): 27 (en), 91 (en), 243 (en), 963 (en)

* Initial code changes to support the new possibleLengths infrastructure
when building metadata. Includes setting these in the main metadata
file and changing the code to populate them in the PhoneMetadata proto
at build time. Updating tests for Java.

* Updating comment about the possible_lengths_local_only field.

* Adding the generated jars that build files containing the new possible
lengths fields.

* Rebuilding short-number metadata with the new proto field. Not doing
this at release time so we can see what changes in the metadata are due
to metadata fixes, rather than this possibleLengths field.

* Regeneration of phone number metadata with the new possible length
information filled in.

Includes some possible length changes for KR and BY, and a validation
fix for NA where a digit was missing.

* Updating the test proto metadata files with the new possible length
information.

* Added notes about the code changes.

* Regenerating C++ metadata with new possibleLength info and updating unit
test to check this works.
