NOTE: This is a breaking change.
The onRequest callback on the HTTP server have been removed in favor
of the ability to register handlers. A handler can be either a
function or an instance of a class which implements a specific
interface. Each handler registration has a regular expression which is
matched against the request path.
There is also a default handler which can be set to handle all
requests which is not matched by any of the registered patterns. If
there is no default handler explicitly set there is a builtin one
which will just return 404 status.
Currently the method is not considered in the matching.
