Add brigde parameter to --netif options

In Proxmox VE we want to support multiple bridges. I currently use
a patch which adds an bridge parameter to the netif options:

NETIF="ifname=XXX,bridge=XXX,mac=XXX,host_ifname=XXX,host_mac=XXX"

--netif_add ifname[,mac,host_ifname,host_mac,bridge]

I also modified --netif_add to accept empty parameters, for example:

--netif_add eth3,,,,vmbr3
