It is based on suggestions from malc and Kevin Wolf.

Currently the qemu user-mode networking stack reads the host DNS
configuration (/etc/resolv.conf or the Windows equivalent) only once
when qemu starts.  This causes name lookups in the guest to fail if the
host is moved to a different network from which the original DNS servers
are unreachable, a common occurrence when the host is a laptop.

This patch changes the slirp code to read the host DNS configuration on
demand, caching the results for at most 1 second to avoid unnecessary
overhead if name lookups occur in rapid succession.  On non-Windows
hosts, /etc/resolv.conf is re-read only if the file has been replaced or
if its size or mtime has changed.

Three problems with our_addr:

- It's determined only once when qemu starts, but the address can change
(just like the DNS configuration can).

- It's supposed to be the IP address of a host network interface, but
there's no guarantee that gethostbyname(gethostname()) actually does
that: the host might be a laptop that has only a loopback interface up,
or the hostname might be localhost.localdomain, etc.

- It's useless at best: get_dns_addr() calls it, there's no reason to
send DNS requests to a different IP address if you're running a DNS
server on the host and resolv.conf points to 127.0.0.1.

These problems are easily solved by removing the code.

With that patch applied "-balloon virtio,args" becomes a shortcut for
"-device virtio-balloon-pci,args".

Side effects:
 - ballon device gains support for id=<tag>.
 - ballon device is off by default now.
 - initialization order changes, which may in different pci slot
   assignment depending on the VM configuration.
