hostip: support wildcard hosts

This adds support for wildcard hosts in CURLOPT_RESOLVE. These are
try-last so any non-wildcard entry is resolved first. If specified,
any host not matched by another CURLOPT_RESOLVE config will use this
as fallback.

Example send a.com to 10.0.0.1 and everything else to 10.0.0.2:
  curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \
       https://a.com https://b.com

This is probably quite similar to using:
  --connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443

Closes #3406
