A function call with an empty bitmap leads to undefined
behavior. Because if 'bitmap->map_len == 0' 'unusedBits' will be <= 0
and 'sz == 1'. So the non global and non static variable 'bits' would
have never been set. Consequently the check 'bits == 0' results in
undefined behavior.
This patch clarifies the current version of the function by handling the
empty bitmap explicitly. Also, for an empty bitmap there is obviously no
bit set so we can just return -1 (indicating no bit set) right away. The
explicit check for 'bits == 0' after the loop is unnecessary because we
only get to this point if no set bit was found.

future, an unenforceable attempt to set the guest-side IP info could
be made by adding a static host entry to the appropriate dnsmasq
configuration (or changing the default dhcp client address on the qemu
commandline for type='user' interfaces), or enhancing the guest agent
to allow setting an IP address, but for now it can't have any effect,
and we don't want to give the illusion that it does.
To prevent the "disappearance" of any existing configs with ip
address/route info (due to parser failure), this check is added in the
newly implemented qemuDomainDeviceDefValidate(), which is only called
when a domain is defined or started, *not* when it is reread from disk
at libvirtd startup.

conf: use virNetDevIPInfo in virDomainHostdevCaps
a.k.a. <hostdev mode='capabilities' type='net'>.
This replaces the existing nips, ips, nroutes, and routes with a
single virNetDevIPInfo, and simplifies the code by calling that
object's parse/format/clear functions instead of open coding.
