libsoup branched for 2.22

[Dan Winship <danw gnome org>]

I've branched libsoup for 2.22 and updated jhbuild.

Some development for 2.24 has been going on on various branches of
http://gnome.org/~danw/libsoup.git, and some of that will be merged to
svn trunk soon.

Plans for 2.24 include:

    - Stuff needed for the WebKit libsoup backend. Especially stuff
      needed for the WebKit libsoup backend needed for Epiphany.

    - Stuff other libsoup users have asked for

Which currently means:
