Kioslave repos

[Alex Merry]

Aleix wanted a separate thread for this, so here it is.

The current runtime splitting plan says that ioslaves should be in three
places: core ones (file, http, etc) in kio, other useful ones (archive,
bookmarks, etc) in "kioslaves", and curiosities (cgi, finger) in
kioslave-extra.

In my view, this is too many repos (and I apologise for not bringing it
up sooner, but the last I'd seen on the list, only one repo outside kio
was being suggested, and I hadn't realised the plan had changed).

Moving things between repos is a *pain*, and I think Ben and Albert have
a point about being over-eager to split things up.  In this case, I
think we should just have core things in kio, and everything else in
kioslaves (or call it kio-extra-slaves, or whatever). Everything in that
package should be optional, and distros can split it up if they really
want, but I don't think we should split it.
