In particular, targets with weight 0 should be very UNlikely to be
selected, not very likely, as they were before. However, even ignoring
that bug in the logic, there was an additional bug (swapping list
items would cause the 0-weight items to get re-ordered incorrectly
anyway), and the code contained several fencepost errors.
This patch also adds gio/tests/srvtarget.c, which confirms that for a
sample list of targets, we now generate all possible correct random
sortings and no incorrect sortings, and the correct sortings occur in
roughly the expected proportions (though if the current code is
still wrong, those proportions may be wrong as well).

Higher-level wrappers around GResolver. GSocketConnectable provides an
interface for synchronously or asynchronously iterating multiple
socket addresses, with GNetworkAddress and GNetworkService providing
interfaces based on hostname and SRV record resolution.
Part of #548466.
GResolver provides asynchronous (and synchronous-but-cancellable) APIs
for resolving hostnames, reverse-resolving IP addresses back to
hostnames, and resolving SRV records. Part of #548466.
