AgentMsgFilter needs to know whether monitors config messages need to be
filtered or not. This used to be done from within
agent_msg_filter_config() using the global RedsState, but this got more
tricky as it was removed.
A first attempt a1e62fa5ae caused crashes on qemu startup with
"qemu-system-x86_64 -spice port=5900" (without -vga qxl). A second
attempt added a RedsState* argument to agent_msg_filter_config() which
in my opinion is not really nice from a layering point of view.
This new attempt makes sure AgentMsgFilter state is correct when the
filter is set to stop discarding all data, which allows to remove direct
use of RedsState from within AgentMsgFilter.
