slirp: Only start packet expiration for delayed ones

The expiration timeout must only affect packets that are queued due to
pending ARP resolutions. The old version broke ping e.g.

slirp: Read current time only once per if_start call

No need to update the current time for each packet we send from the
queue. Processing time is comparably short.

slirp: Fix types of IP address parameters

Should be uint32_t for IPv4, not int. Also avoid in_addr_t without
proper includes. Fixes build regression on mingw32.

Delayed IP packets

In the current implementation, if Slirp tries to send an IP packet to a client
with an unknown hardware address, the packet is simply dropped and an ARP
request is sent (if_encap in slirp/slirp.c).

With this patch, Slirp will send the ARP request, re-queue the packet and try...

Simple ARP table

This patch adds a simple ARP table in Slirp and also adds handling of
gratuitous ARP requests.

slirp: Fix unusual "comments" in unused code

cppcheck detected two rather strange comments which were not
correctly written as C comments.

They did not cause any harm because they were framed by
#ifdef notdef ... #endif, so they were never compiled.

Fix them nevertheless (we could also remove the unused code)....

Wrap recv to avoid warnings

Avoid warnings like these by wrapping recv():

slirp: Forward ICMP echo requests via unprivileged sockets

Linux 3.0 gained support for unprivileged ICMP ping sockets. Use this
feature to forward guest pings to the outer world. The host admin has to
set the ping_group_range in order to grant access to those sockets. To...

slirp: Put forked exec into separate process group

Recent smb daemons tend to terminate themselves via a process group
SIGTERM. If the daemon is still in qemu's group by that time, qemu will
die as well. Avoid this by always pushing fork_exec processes into a...
