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

Remove linux tests from travis.

Fix sign-comparison warnings and add a test for that.

When it runs in parallel with other jenkins tests, multiple tests start
to fail probably because cpp_distcheck will update the C++ lib that
other tests (such as python_cpp) are depending on.

These tests are already covered by jenkins and right now jenkins can
finish these tests much quicker then travis.

grpc build treates them as errors and such issues (protobuf change
breaks grpc) has been reported repeatedly. For example:

Add more tests to jenkins.

Fixes the parsing of the proto-framework map file.

 - Fixes memory issue where the pointer to the StringPiece would be allocated on the stack, and would mangle the output.
 - Fixes length of the file name when parsing the comma separated files.

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.

Update travis tests for Java.

1. Set JAVA_HOME so mvn can pick up the correct java version.
2. Remove jdk6 tests. It has been broken for a while and remain undetected as
   mvn is actually using java 7 to build the code. Given that we have
   set -source and -target to 6 in the pom.xml and the built .jar
   should be usable by java 6, having a dedicated java 6 test doesn't
   seem necessary (assuming very few Java 6 users want to compile protobuf
   Java from source).

Add missing files in EXTRA_DIST and add a test.

JavaScript: segregate references to binary functionality

Include javadoc/source in Java release packages.

Also fixed javadoc errors.

[ci skip]

This change will help us separate binary support into
separate files, because we only refer to binary serialization
functions in the actual binary serialization paths.

Added 3.0.0-beta-4 changelog.

Use public methods to fetch oneofs in generated code.

When building into frameworks, the generated code doesn't always have direct
access to the proto internals.  Instead of opening up the access, just use the
public method to fetch the correct oneof.

Fixes https://github.com/google/protobuf/issues/1789

Change-Id: Ic07a7c664930209974244c66885d672288982610

Exposes the currently registered extensions for a message and removes the internal sortedExtensionsInUse

Uses head version of rvm to avoid shell_update_session not found error

Fixes #1786
