sockets: Make inet_parse() non static.

From: Bharata B Rao <bharata@linux.vnet.ibm.com>

Make inet_parse() non-static so that other subsystems like gluster
can use it to parse inet addresses. As a pre-requisite, define and
globalize the qemu_inet_opts.

Making the option list global sounds fine, but I don't think it should
be moved to qemu-config.c or added to vm_config_groups, which is
generally used for command line options and config file entries. At
least I can't imagine a command line option -inet would be very useful.

Yes.  Also, I'll send a pull-request for
http://patchwork.ozlabs.org/patch/180237/ soon, so you might as well
take that patch.

Ok, this patch is good enough for gluster usecase. I will include this in my
v8 post if its not upstream by that time.
