Connect vif's to already running VMs on NetVM/ProxyVM startup (#190) Also cleanup stale vifs using "xm network-detach ... -f" Fix iptables rules to support not only first vif of VM

vm: route through specific host, not directly interface (#355) This it to not fill ARP cache with any host that VM connects to.

setup_ip: turn off sg Apparently vif frontend has broken sg implementation; we already worked around it in init.d script via ethtool; now do the same in setup_ip. It is relevant when attaching firewallvm to a different netvm on the fly.

qvm-prefs: allow on the fly netvm switch (#302) When changing netvm of a running vm, detach/attach eth0. Some functionality of qubes_core_netvm thus is duplicated in setup_ip. REQUIRES http://git.qubes-os.org/?p=rafal/xen.git;a=commit;h=42c72e6173586a807f8f153391e2e57352d362b1

The Underscores Revolution: filenames Get rid of underscores in filenames, use dashes instead. This is first part of cleanup in filenames. "qubes_rpc" still untouched - will be in separate commit.

# XXX: Backward compatibility
vm: allow user-define hook for IP change event This is especially useful for proxy VMs that e.g. run some transparent proxy service such as tor, and need to rebind it upon IP change (of course this assumes iptables-based transparent redirection such as DNAT).
