* Factored Conformance test messages into shared test schema.

* Updated benchmarks to use new proto3 message locations.

* Fixed include path.

* Conformance: fixed include of Python test messages.

* Make maven in Rakefile use --batch-mode.

* Revert changes to benchmarks.

On second thought I think a separate schema for
CPU benchmarking makes sense.

* Try regenerating C# protos for new test protos.

* Removed benchmark messages from test proto.

* Added Jon Skeet's fixes for C#.

* Removed duplicate/old test messages C# file.

* C# fixes for test schema move.

* Fixed C# to use the correct TestAllTypes message.

* Fixes for Objective C test schema move.

* Added missing EXTRA_DIST file.

This makes a couple of changes to fix the tests for JRuby 1.7:
- Avoid using assert_false since that assertion seems not to exist in
  older versions
- Disable a test related to respond_to? for JRuby. It's hard to tell
  what is going wrong here but it looks like probably a JRuby bug that
  has been fixed in more recent versions.

Uses values from the removed `Gemfile.lock` as a baseline for version requirements, though it has been observed to work with the latest versions of all the referenced gems - see https://travis-ci.org/google/protobuf/builds/163625616 for details

`System.identityHashCode` returns a hash that does not consider a
Message's values. This means two Messages with identical values will not
have identical hashCodes.

This patch uses the pattern from RubyMap to combine the hashCodes from
all values in a given message and produce a unique, consistent,
value-based hash.

`System.identityHashCode` returns a hash that does not consider a

This patch uses the pattern from RubyMap to combine the hashCodes from
all values in a given message and produce a unique, consistent,
value-based hash.

Instead of shifting/xoring the hash at each field, use the built-in ruby
apis for generating a hash from multiple input values.

Now returns a Fixnum.

* add a repeated field to the tested hash
* also assert that two messages with identical values produce identical hashes

Ruby: make sure map parsing frames are GC-rooted.

This will allow loading the extension for Ruby 2.1.10...

This brings us more into line with other langauges, and makes it more
obvious when we are requiring protobuf generated code.

1. Added ruby22 and jruby tests to jenkins.
2. Added javascript tests to jenkins.
3. Added golang tests to jenkins.
4. Removed ruby19/ruby20 tests from travis. Support for ruby 2.0 has
   ended since 2016/02/24.
