Currently you can specify whether you want a UDP chardev backend to be IPv4 or IPv6 using the ipv4 or ipv6 options if you use the QemuOpts parsing code in inet_dgram_opts(). However the QMP struct parsing code in socket_dgram() doesn't provide this flexibility (which in turn prevents us from converting the UDP backend handling to the new style QAPI framework).
Use the existing inet_addr_to_opts() function to convert the remote->inet address to option strings; this handles ipv4 and ipv6 flags as well as host and port. (It will also convert any 'to' specification, which is harmless as it is ignored in this context.)
