Add Completable to documentation in RxJava2CallAdapterFactory

Okio proguard rules link

Revert back to an OnSubscribe-based RxJava adapter.

Readme fixes

Update checkstyle to the latest version.

This allows proper cancelation of the underlying Call which wasn't supported in the fromCallable method.

OkHttp 3.5.0

This adds support for automatic BOM handling when character-based mechanisms are used on ResponseBody.

Remove RoboVM support.

The project died quickly after we merged support, and I must have been high to let someone convince me this was a good idea to add.

If you still need RoboVM support supply your own callback executor to Retrofit.Builder.

Add sample showing how to add an observeOn to Observable.

Import RxJava 2 CallAdapter.Factory

From https://github.com/JakeWharton/retrofit2-rxjava2-adapter

Reflect OkHttp Call canceled state from our Call.

Add shallow-copy newBuilder() method to Retrofit.

Use latest moshi.

Remove incorrect comment as client is immutable.

Close ResponseBody on 204/205 to avoid connection leak

Update RxJava adapter to 1.2.0.

Use a more idiomatic creation mechanism which eliminates a lot of responsibility for our implementation.

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
