glib unicode regular expression api

[Matthias Clasen <mclasen redhat com>]

GLib has a longstanding enhancement request to add
a Unicode regular expression API
(http://bugzilla.gnome.org/show_bug.cgi?id=50075)

I have put a candidate for this into libegg now (in the regex module),
since we felt that the proposed API wasn't tested enough to go into 2.6.
I would be happy if people interested in regular expressions would give
this a try and comment on it.

Speaking about libegg, I wonder about the status and destination of some
modules: background-monitor and recent-files don't have any obvious
destinations, what is their status ? background-monitor seems pretty
uninteresting, but recent-files seems to have found broad use, and
should probably be moved into a platform library (considering that
federico already presented it as "Gnome API" in his fashion show).
