Fixing environments where pkg-config isn't installed.

Moving our build status badge from Travis to Jenkins.

The code evolved enough so that we now have tests that directly depend on OpenSSL

Return normalized IPv4 addresses from grpc_sockaddr_to_uri().

Users of the high-level API should not care whether we're using AF_INET
or AF_INET6 sockets internally.

Addenda to tools readme

Upgrading to OpenSSL 1.0.2d

Pass NULL as host by default. Use context.authority() or channel.SslN…

Affirm metadata transmission in a common function

Runtest polishing

Depending on the presence of pkg-config, we're not necessarily doing the right thing in the Makefile. Zlib is a pkg-config dependency, but libm, libpthread, librt aren't.

C# Improving Channel API

Properly decrement active_ports on server shutdown on Win.

Use an unsigned pointer compare, as the highest bit may sometimes be set.

This fixes intermittent connection issues on 32-bit Linux. Also related
to issues #2557 and #2600.

Have the tests preferably use the protoc compiled by make.

Adding a sanity check that the cached makefile variables aren't committed.

Fix compilation under VS 2010

Fix alpn_test

Add accessor peer() in ClientContext and ServerContext

Made binding a server to a port insecurely explicit

Make FileNameInUpperCamel aware of directories
