destroy_nic() requires that NICInfo::private by a PCIDevice pointer,
but then goes on to require that the same pointer matches
VLANClientState::opaque.

That is no longer the case for virtio-net since qdev and wasn't
previously the case for rtl8139, ne2k_pci or eepro100.

Make the situation a lot more clear by maintaining a VLANClientState
pointer in NICInfo.

In order to not execute code we just compiled, let's replace signrom
with a shell script that does the same thing while staying compatible
to pretty much every system available.

This should make cross-compilation for windows easier.

On reflection, perhaps it does make sense to set a default value for
the sndbuf= tap parameter.

For best effect, sndbuf= should be set to just below the capacity of
the physical NIC.

Setting it higher will cause packets to be dropped before the limit
is hit. Setting it much lower will not cause any problems unless
you set it low enough such that the guest cannot queue up new packets
before the NIC has emptied its queue.

In Linux, txqueuelen=1000 by default for ethernet NICs. Given a 1500
byte MTU, 1Mb is a good choice for sndbuf.

If it turns out that txqueuelen is actually much lower than this, then
sndbuf is essentially disabled. In the event that txqueuelen is much
higher, it's unlikely that the NIC will be able to empty a 1Mb queue.

Thanks to Herbert Xu for this logic.

The only purpose DeviceType serves is creating a linked list of

BusInfo is filled with name and size (pretty much like I did for
DeviceInfo as well).  There is also a function pointer to print
bus-specific device information to the monitor.  sysbus is hooked
up there, I've also added a print function for PCI.

Device creation is slightly modified as well:  The device type search
loop now also checks the bus type while scanning the list instead of
complaining thereafter in case of a mismatch.  This effectively gives
each bus a private namespace for device names.

There's a error When doing something like that :

[ done in a arm chroot with qemu-arm and linux binfmt stuff or with
find / -type f -print0 | qemu-arm -L <path> <path>/usr/bin/xargs -0
echo ]

Doing this outsite qemu is fine. The problem was the huge number of
parameters. Increasing MAX_ARG_PAGES is fixing that.

While I was at it, I've modified linux-user/main.c to report error code
of loader_exec. It helps to debug/know what's wrong.
