API Additions

Bug Fixes

API-Incompatible Changes

- `rouver.handler`: RouteHandlerBase is now an ordinary WSGI application.
It takes an WSGI environment and a start response handler as constructor
arguments.
- `rouver.handler`: Redesign RouteHandlerBase API. Implementations must now
implement `prepare_response()` instead of `__iter__()`.
- `rouver.handler`: All response methods now return an iterable instead
of an iterator.
- `rouver.handler`: `RouteHandlerBase.path_args` is now acquired from the
WSGI environment and will not contain the wildcard path.
- `rouver.response`: All response functions now return an iterable instead
of an iterator.
- `rouver.router`: `add_routes()` now requires a regular WSGI
application instead of a route handler.
- `rouver.types`: Remove `RouteHandler`. `RouteDescription` now expects
an `WSGIApplication` in the third field.

API Additions

- `rouver.handler`: Add `RouterHandlerBase.wildcard_path`.
- `rouver.router`: Add a field `rouver.path_args` to the WSGI environment
that contains the path arguments formerly passed to route handlers as the
second argument. The wildcard path is not added to this field.
- `rouver.router`: Add a field `rouver.wildcard_path` to the WSGI
environment that contains the wildcard path or the empty string.

API Additions

- `rouver.router`: Support sub-routers.
