	* camel-provider.h: Tweak the definition of CamelProvider. Among
	other things, a provider may now be both a store and a transport.

	* camel-provider.c: Remove a lot of code we had no intention of
	using. This now only contains two functions: camel_provider_init
	to read the installed .urls files, and camel_provider_load to
	load and register a new provider.

	* camel-session.c: Remove more unused code and simplify some of
	the remaining code. The list of available provider modules is now
	stored in the session, and it handles calling camel_provider_load
	to load them as needed. Provider registration is now done by
	calling back from the module init routine, which allows a single
	module to register providers for multiple URL types.

	* providers/*: Update provider structures and init routines for
	the new stuff. Add a .urls file to each provider specifying what
	urls it handles, and install that with the library.

	* providers/nntp/camel-nntp-provider.c: Add hints towards
	supporting both news: and nntp: URLs, and using nntp as both a
	store and a transport.
