* Add binary conformance tests for map fields
* Update failure list
* Fix php conformance test
* Fix php conformance test
In 32-bit platform, int64 should be string. However, map iterator returns string key as integer.
* Add more test cases for map
* Update failure list
* Test singular fields are encoded in canonical way
* Defautl values in proto3 should not be encoded.
* Values should be converted to the canonical representation (e.g.,
long int64 value may be truncated for int32 field)
* Update failure list
* Update failure list
* Add conformance tests for explicit packed/unpacked fields
* Fix typo
* Update failure lists
* Update failure list
* Use enum class to make enum scoped
* Add binary conformance test for default repeated fields
1) Both packed and unpacked encoding should be accepted for parsing.
2) Encode should follow the default way for the syntax.
* Uncomment test
* Remove is_primitive
* Add failed tests to failure lists.
* Add failed test to failure list
* Use binary format to specify expected value
Text format cannot distinguish whether repeated field is packed or not.
* Change method name from ToHexString to ToOctString
* Add failed test to failure list
* Add failed test to php's failure list
* Fix comments
* Adopt upb change for timestamp and duration json to php
* Remove unused code
* Re-sync upb
* Fix php implementation timestamp json parsing
* Fix strptime use local timezone on mac.
* Remove succeeding tests
* Resync
* Add tests for values
* Fix php tests
* Fix encoder handlers change default value
Previously, oneofsubmsg_handler and submsg_handler change zval's default value directly.
The fix use REPLACE_ZVAL_VALUE which create a copy of parsed value and assign it to zval.
* Add conformance test for php c back
php c extension has different result for conformance test for different
php version and architecture. Try to add conformance back for php 7.1 c extension first.
* Disable conformance test for c extension on 32-bit architecture
32-bit and 64-bit have different failing tests
* Fix typo
