qdev: Use GList for global properties
If the same GlobalProperty struct is registered twice, the list
entry gets corrupted, making tqe_next points to itself, and
qdev_prop_set_globals() gets stuck in a loop. The bug can be
easily reproduced by running:
$ qemu-system-x86_64 -rtc-td-hack -rtc-td-hack
Change global_props to use GList instead of queue.h, making the
code simpler and able to deal with properties being registered
twice.
