Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

The properties of netfilter object could be changed by 'qom-set'
command, but the output of 'info network' command is not updated,
because it got the old information through nf->info_str, it will
not be updated while we change the value of netfilter's property.
Here we split a helper function that could collect the output
information for filter, and also remove the useless member
'info_str' from struct NetFilterState.

Previously, if we attach more than one filters for a single netdev,
both ingress and egress traffic will go through net filters in same
order like:
ingress: netdev ->filter1 ->filter2 ->...filter[n] ->emulated device
egress: emulated device ->filter1 ->filter2 ->...filter[n] ->netdev.
This is against the natural feeling and will complicate filters
configuration since in some scenes, we hope filters handle the egress
traffic in a reverse order. For example, in colo-proxy (will be
implemented later), we have a redirector filter and a colo-rewriter
filter, we need the filter behave like:
ingress(->)/egress(<-): chardev<->redirector<->colo-rewriter<->emulated device
Since both buffer filter and dump do not require strict order of
filters, this patch switches to always let egress traffic walk through
net filters in reverse to simplify the possible filters configuration
in the future.

Currently the ObjectProperty iterator API works as follows:
ObjectPropertyIterator *iter;
iter = object_property_iter_init(obj);
while ((prop = object_property_iter_next(iter))) {
...
}
object_property_iter_free(iter);
This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.
This patch changes the API to use stack allocation instead:
ObjectPropertyIterator iter;
object_property_iter_init(&iter, obj);
while ((prop = object_property_iter_next(&iter))) {
...
}

Stop directly accessing the Object::properties field data
structure and instead use the formal object property iterator
APIs. This insulates the code from future data structure
changes in the Object struct.

Add a netfilter object based on QOM.
A netfilter is attached to a netdev, captures all network packets
that pass through the netdev. When we delete the netdev, we also
delete the netfilter object attached to it, because if the netdev is
removed, the filter which attached to it is useless.
