Add support for DHCP on bridges (#125259, original patch by Anders Kaseorg
<anders@kaseorg.com>): - rc.d/init.d/network: Initialize bridges after bridged interfaces, deinitialize them before bridged interfaces - sysconfig/network-scripts/ifdown-eth: Destroy bridges lazily when the last bridged interface is stopped - sysconfig/network-scripts/ifup-eth: * Handle bridges before checking for module presence or wireless devices * Add bridges lazily when the first bridged interface is started
