network: escape quotes for dsmasq conf contents dnsmasq conf file contents needs to have quotes escaped for it to work. Because of this, the network-create/start for a network with quotes in the name fails. The patch escapes strings for the entries that go into the conf file.

network: add netmask to dhcp range of dnsmasq conf file for IPv4 dnsmasq documentation says that the *IPv4* prefix/network address/broadcast address sent to dhcp clients will be automatically determined by dnsmasq by looking at the interface it's listening on, so the original libvirt code did not add a netmask to the dnsmasq commandline (or later, the dnsmasq conf file). For *IPv6* however, dnsmasq apparently cannot automatically determine the prefix (functionally the same as a netmask), and it must be explicitly provided in the conf file (as a part of the dhcp-range option). So many years after IPv4 DHCP support had been added, when IPv6 dhcp support was added the prefix was included at the end of the dhcp-range setting, but only for IPv6. A user had reported a bug on a host where one of the interfaces was a superset of the libvirt network where dhcp is needed (e.g., the host's ethernet is 10.0.0.20/8, and the libvirt network is 10.10.0.1/24). For some reason dnsmasq was supplying the netmask for the /8 network to clients requesting an address on the /24 interface. This seems like a bug in dnsmasq, but even if/when it gets fixed there, it looks like there is no harm in just always adding the netmask to all IPv4 dhcp-range options similar to how prefix is added to all IPv6 dhcp-range options.

network: add dnsmasq option 'dhcp-authoritative' The dnsmasq man page recommends that dhcp-authoritative "should be set when dnsmasq is definitely the only DHCP server on a network". This is the case for libvirt-managed virtual networks. The effect of this is that VMs that fail to renew their DHCP lease in time (e.g. if the VM or host is suspended) will be able to re-acquire the lease even if it's expired, unless the IP address has been taken by some other host. This avoids various annoyances caused by changing VM IP addresses.
