c-ares now does support IPv6;
avoid implying threaded resolver is Windows-only;
two referenced source files were renamed in 7de2f92

- hostsyn.c  - functions for synchronous name resolves
- hostares.c - functions for ares-using name resolves

  The hostip.h is the single united header file for all this. It defines the
