vhost-user_net, vm-virtio, vmm: Permit host MAC address setting

Browse Source 
Add a new "host_mac" parameter to "--net" and "--net-backend" and use
this to set the MAC address on the tap interface. If no address is given
one is randomly assigned and is stored in the config.

Support for vhost-user-net self spawning was also included.

Fixes: #1177
