Method level:
 * `@FormEncoded`
 * `@Multipart`

Parameter level:
 * `@Path` - URL path replacement
 * `@Query` - URL query string
 * `@Pair` - Form-encoding pair
 * `@Part` - Multi-part part
 * `@Body` - Single-object body (Old `@SingleEntity`)

This removes support for `@QueryParam`/`@QueryParams` in favor of including constants in the declared URL itself. e.g.,

    @GET("/list?foo=bar")

Allow digits in path parameter name

Modify PATH_PARAMETERS regular expression to allow path parameter names that
are strings containing lowercase characters, digits, underscores, or hyphens
that start with a lowercase character. Closes #199.

Bump GSON to latest stable.

Add OkHttp-specific client when its present on the classpath.

Exposes the static RetrofitError construction methods

Allows `RetrofitError`s to be thrown from code outside of Retrofit

Reset thread name to idle when not in use.

Closes #188.

Issues with new multi-part implementation

* Added fileName() to TypedOutput so non-File parts can be named.
* Support Content-Length in multipart requests.
* Serialize parts to byte[]s so length is available.

Eagerly consume a stream when exposing to caller.

HTTP responses return an input stream wrapped in a TypedInput which we pass to the converter for deserialization as fast as the bytes come in. If we are skipping the converter (non-2xx resposne code) or returning the response directly we eagerly consume the stream to a byte[] for the caller.

If the converter threw an exception while reading the stream then it is nulled out before being handed to the RetrofitError. This prevents partially read streams from being exposed.

Closes #181.

Adds in missing quotation mark in Content-Disposition header

Fixed missing quotation mark which caused multipart file uploads to parse without a filename, leading to missing files in requests on the server side

Roll our own multi-part implementation.

Drop Apache mime4j dependency.

Closes #141.

Abstract logging API.

This also fixes a race condition in the RestHandler's dealing with the response of `server.getUrl()`. Theoretically the response of that invocation could change between creating the request and assembling the profiler information. Cache the result in a local variable and re-use.

Closes #142.

Remove pre/post override points for ApacheClient.

All customization should be done by overriding execute.

Only using getErrorStream() for status >= 400

Making TestingUtils abstract so that JUnit ignores
