In unsuccessful scenarios, such as redirects, error handling converts a
`Response` into an exception. When a user defines a return type as
`Response`, we can assume they will want access to things like headers
even in an error scenario.
See #249
Before this change, apis that follow patterns across a service could
only be modeled by copy/paste/find/replace. Especially with a large
count, this is monotonous and error prone.
This change introduces support for base apis via single-inheritance
interfaces. Users ensure their target interface bind any type variables
and as a result have little effort to create boilerplate apis.
Ex.
```java
@Headers("Accept: application/json")
interface BaseApi<V> {
@RequestLine("GET /api/{key}")
V get(@Param("key") String);
@RequestLine("GET /api")
List<V> list();
@Headers("Content-Type: application/json")
@RequestLine("PUT /api/{key}")
void put(@Param("key") String, V value);
}
interface FooApi extends BaseApi<Foo> { }
interface BarApi extends BaseApi<Bar> { }
```

Previously, the Retryer instance provided to the Builder was simply reused, but the instance keeps per-request state, causing repeatable requests to stop being retried. Fixes#236
Before, LBClients were created for each request, which led to issues
such as #182. Moreover, a user could not avoid using Ribbon's static
factories. Adding LBClientFactory allows users to control how Ribbon
resources are created.
Files had various formatting differences, as did pull requests. Rather than
create our own style, this inherits and requires the well documented Google
Java Style.
Feign has `MethodMetadata.bodyType()`, but never passed it to encoders.
Encoders that register type adapters need to do so based on the
interface desired as opposed to the implementation class. This change
breaks api compatibility for < 8.x, by requiring an additional arg
on `Encoder.encode`.
see https://github.com/square/retrofit/issues/713
Dagger 1.x and 2.x are incompatible. Rather than choose one over the
other, this change removes Dagger completely. Users can now choose any
injector, constructing Feign via its Builder.
This change also drops support for javax.inject.Named, which has
been replaced by feign.Param.
see #120
Parameters annotated with `Param` expand based on their `toString`. By
specifying a custom `Param.Expander`, users can control this behavior,
for example formatting dates.
```java
@RequestLine("GET /?since={date}") Result list(@Param(value = "date", expander = DateToMillis.class) Date date);
```
Closes#122
Feign 8.x will no longer support Dagger, nor interfaces annotated with `javax.inject.@Named`. Users must migrate from `javax.inject.@Named` to `feign.@Param` via Feign v7.1+ before attempting to update to Feign 8.0.
For example, the following uses `@Param` as opposed to `@Named` to annotate template parameters.
```java
interface GitHub {
@RequestLine("GET /repos/{owner}/{repo}/contributors")
List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo);
}
```
Adds a new "slf4j" module. A few methods in Logger are now protected rather
than package protected to allow access by Logger subclasses that aren't
inner classes of Logger.
Request/Response/RequestTemplate are now fundamentally based on a byte[] body field.
For Request/RequestTemplate, if a charset is provided, it can be treated as text.
For many users of the library, the change should barely be noticeable, as the methods that
were changed were mostly used internally.
There were some non-backwards-compatible signature changes that require a
major version bump, however.

Initial implementation of Jackson codec
This new codec may be used as an alternative to Gson.

Improve EncodeException and DecodeException Javadoc comments
This changeset adds a simple request interceptor that performs HTTP basic authentication.
The HTTP spec isn't very clear on the use of character encodings within this header.
The most common interpretation in servers appears to be to expect ISO-8859-1, so I've
used that as a default, as well as allowing the encoding to be specified.
At @adriancole's suggestion, sun.misc.BASE64Encoder is used for the base64 encoding
rather than pulling an implementation into the Util class. If we ever run into a JRE that
doesn't provide compatibility with that class, we can eliminate that dependency.
The logic in GsonCodec was split into GsonEncoder and GsonDecoder, each of which can
now be used separately. GsonCodec was deprecated, and can be removed in the next major
version. To facilitate use outside of Dagger, the double-to-int map type adapter was broken into
its own class, and is included by default when using the default constructors of either the
encoder or decoder. The examples have been updated to use the new encoder/decoder instead
of the codec.
