ANNOUNCE: c-ares version 1.7.4

Hi friends,

I'm happy to announce c-ares version 1.7.4. It was just tagged, signed and
uploaded to the site: http://c-ares.haxx.se/

Changed:

  o local-bind: Support binding to local interface/IPs, see
    ares_set_local_ip4, ares_set_local_ip6, ares_set_local_dev

Fixed:

  o memory leak in ares_getnameinfo
  o add missing break that caused get_ares_servers to fail
  o ares_parse_a_reply: fix CNAME response parsing
  o init_by_options: don't copy an empty sortlist
  o Replaced uint32_t with unsigned int to fix broken builds
    on a couple of platforms
  o Fix lookup with HOSTALIASES set
  o adig: fix NAPTR parsing
  o compiler warning cleanups

Thanks go to these friendly people for their efforts and contributions:

  Andrew C. Morrow, Ben Greear, Ben Noordhuis, Daniel Stenberg,
  Guenter Knauf, Mike Crowe, Patrik Thunstrom, Yang Tse
