libpq: Allow connection strings and URIs to specify multiple hosts.
It's also possible to specify a separate port for each host.
Previously, we'd loop over every address returned by looking up the
host name; now, we'll try every address for every host name.
Patch by me. Victor Wagner wrote an earlier patch for this feature,
which I read, but I didn't use any of his code. Review by Mithun Cy.
