A bridge device with only one underlying ethernet device is almost
useless, for sure we want to support a bridge with multiple
underlying devices.
This patch adds the support by extending <ethname> in the original
bridge= cmdline to a comma-separated list of ethernet interfaces.

Format:
bond=<bondname>[:<bondslaves>:[:<options>]]
bondslaves is a comma-separated list of physical (ethernet) interfaces.
options is a comma-separated list on bonding options (modinfo bonding for
details) in format compatible with initscripts.
If options include multi-valued arp_ip_target option, then its values
should be separated by semicolon.
bond without parameters assumes bond=bond0:eth0,eth1:balance-rr
* SYNTAX
bridge=<bridgename>:<ethname>
If bridge without parameters, assume bridge=br0:eth0
* When <ethname> would be configured by network scripts, instead create a bridge named <bridgename> then add <ethname> to that bridge.
* Then $netif becomes <bridgename> instead of <ethname> and all existing scripts process netroot mount via this new $netif instead of <ethname>.
* Include a few test cases in NFS and NBD
