Refactor manifest list operations

* Update method/function signatures use the manifest list name and
  images associated with the operation explicitly, in general

  func f(ctx context.Context, manifestListName string,
         ImageNames []string, options *fOptions)

* Leverage gorilla/mux Subrouters to support API v3.x and v4.x for
  manifests
* Make manifest API endpoints more RESTful
* Add PUT /manifest/{id} to update existing manifests
* Add manifests.Annotate to go bindings, uncommented unit test
* Add DELETE /manifest/{Id} to remove existing manifest list, use
  PUT /manifest/{id} to remove images from a list
* Deprecated POST /manifest/{id}/add and /manifest/{id}/remove, use
  PUT /manifest/{id} instead
* Corrected swagger godoc and updated to cover API changes
* Update podman manifest commands to use registry.Context()
* Expose utils.GetVar() to obtain query parameters by name
* Unexpose server.registerSwaggerHandlers, not sure why this was ever
  exposed.
* Refactored code to use http.Header instead of map[string]string when
  operating on HTTP headers.
* Add API-Version header support in bindings to allow calling explicate
  versions of the API. Header is _NOT_ forwarded to the API service.
