Fix Python 3 TypeError in gdb pretty-printers

Python 3 compatibility in bug 720635 was incomplete: iterators need to define __next__.  This was fixed in gobject.py in 7991178a752a22274950e54dc4f05b55ae54d756, but glib.py also has two custom iterators.
Comment 1 Olivier Crête 2015-07-20 19:57:15 UTC 
Any chance we can get this one in? Would be really useful to put it into a stable release too as recent distros are not building gdb against Python 3.
Comment 2 Peter Wu 2015-09-25 12:03:27 UTC 
Attachment 303060 [details] works for me. Existing installations can be patched with:

python
import glib
glib.GListPrinter._iterator.__next__ = glib.GListPrinter._iterator.next
glib.GHashPrinter._iterator.__next__ = glib.GHashPrinter._iterator.next
end

(cc'ing Alexander as he is the original committer)

The patch is still missing in glib2 2.46.2 and git master. It still works, can it be merged?

mclasen said it was fine to push this on IRC, so pushing it!
