Rollup merge of #41582 - jonhoo:reread-nameservers-on-lookup-fail, r=alexcrichton
Reload nameserver information on lookup failure As discussed in #41570, UNIX systems often cache the contents of `/etc/resolv.conf`, which can cause lookup failures to persist even after a network connection becomes available. This patch modifies lookup_host to force a reload of the nameserver entries following a lookup failure. This is in line with what many C programs already do (see #41570 for details). On systems with nscd, this should not be necessary, but not all systems run nscd. Fixes #41570. Depends on rust-lang/libc#585. r? @alexcrichton
