	* src/libsoup/soup-message.c (authorize_handler): Call
	soup_auth_fn if we don't have auth data in the URI, then call
	soup_auth_initialize if the callback set authenticate data on the
	passed uri.

	* src/libsoup/soup-auth.h: Make type be SoupAuthType.

	* src/libsoup/soup-auth.c (soup_auth_initialize): Impl. To be
	called after SoupAuth creation to apply auth data to the
	SoupAuth. This allows us to parse the Authenticate headers to
	figure out which auth scheme and realm is being used, and pass
	this to the auth callback.

	* src/libsoup/soup-misc.c (soup_set_authorize_callback): Impl.

	* src/libsoup/soup-misc.h: Add SoupAuthType enum here.
