Promote adapter response body type parameter to class level.

Add method for returning a Moshi conveter that serializes nulls.

This is a source-incompatible but binary-compatible change. Since we don't expect a lot of third-party adapters, I think this is acceptable.

Replaced invocation of deprecated factory methods in JacksonConverterFactory

Replaced invocation of deprecated factory methods in favor of newer counterparts in JacksonConverterFactory

Propagate fatal exceptions even if already dispatching an error.

Add toString implementations to Response and Result.

Implement proper error handling for Rx types.

Since we've implemented our own observables instead of using the built-in factories we have to do the heavy lifting of these edge cases ourselves.

Switch to a better, custom validating subscriber.

TestSubscriber is a poor implementation for correctness testing. This new subscriber ensures all events are tested by being a JUnit rule. It also consumes events as they're validated so that assertion becomes more like a script than a ledger.

This also switches tests to use unsafeSubscribe to ensure that any contract violations are not being suppressed. The latest version of RxJava is required for accessing this method on Completable.

Simplify observable creation and reduce runtime allocations.

Refactor Rx tests to avoid the use of blocking operators.

Remove duplicated test.

It is the same as  in this file.

Update to support protobuf 3.0.

Add tests for order of multipart request's parts. Issue #1846.

Update to OkHttp 3.4.1

Update to OkHttp 3.4.0.

Skip a UTF-8 BOM if present for the Moshi converter.

Use string converter for String type.

Unlike RequestBody and ResponseBody which are library types that must be handled by default, String is a platform type and we want to ofer the flexibility of doing things like using annotations to transform the contents.
