Allow setting qemu process name v2

Set the Linux process name to the name argument specified with name. I find
this useful to see which guests are taking CPU time in top.

This doesn't affect ps, which checks argv[0], but rewriting the
environment uses much more code, so I only used this simple way.

v2: Use separate process= argument, no prefixes.

configure: Append extra cflags and ldflags

In order to allow overriding flags that are set by configure, we have to
append them instead of prepending as it is done so far.

v2: Clarify documentation.

Don't leak VLANClientState on PCI hot remove

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.

Don't abort if TUNSETSNDBUF fails where no sndbuf= arg is supplied

If no tap,sndbuf= arg is supplied, we use a default value. If
TUNSETSNDBUF fails in this case, we should not abort.
