Deflake dualstack socket test

Update INSTALL for C

Updated Python Status

Missed a step

Synchronize initial package versions

Sanitize a reference number.

The test currently allocates a single port and reuses it through the
test. Given the timeouts in this test this leaves substantial race
windows where other processes on the same machine could steal the port
between subcases.

Instead, as a simple hack, allocate a new port before each test.

Set Python version number to 0.4.0.

Bumped node version to 0.5.0

Update binding.gyp

Changing to use node instead of nodejs

Clarify INSTALL

In-process unit tests with test service, some interop test fixes.

Add Debian nodejs-legacy instructions

Removing emplace from python plugin.

Added better instructions (including the git instructions).

Python ClientCredentials object.

Final changes to the early_adopter API.

Tmp fix: splits the hostname from the host before creating a call

Strip port in peer name check

This string comes from an authority field, which is allowed to contain a
':' port (see https://tools.ietf.org/html/rfc3986#section-3.2).

We need to strip it before performing host name verification.

Update examples/pubsub/README

Update CONTRIBUTING.md

We have decided our release version number shall be 0.5.0.

Go auth tests

Massage wording and fix the instructions for run_tests to remove reference to non-existsant -l all option.
