Git versions of glib, goffice, gnumeric, libgsf and libxml2.

Test case: http://jutaky.com/fuzzing/gnumeric_case_expr.c.2341.gnumeric

I have accustomed to get stack overflows on very large spreadsheets but this one is only 2.3KB. Maybe this is unrelated to the huge XML file stack overflows.

$ gnumeric gnumeric_case_expr.c.2341.gnumeric
