  ares_cancel() could trigger callback with wrong response code (#663)

  When doing ares_gethostbyname() or ares_getaddrinfo() with AF_UNSPEC, if \ 
ares_cancel() was called after one address class was returned but before the \ 
other address class, it would return ARES_SUCCESS rather than ARES_ECANCELLED.

  Test case has been added for this specific condition.

  Use external GoogleTest instead of bundling it (#655)

  GoogleTest should be unbundled. Google changed their guidance a few years back \ 
and modern versions of google test cannot build the bundling code file.

  This PR also updates to use C++14 as is required by modern GoogleTest versions.

  Rewrite sortlist hand parser for memory safety and bugs (#653)

  The parser for the sortlist has been rewritten to use the ares__buf_*() \ 
functions. This also resolves some known bugs in accepting invalid sortlist \ 
entries which should have caused parse failures.

  increment failures on timeout (#651)

  As of c-ares 1.22.0, server timeouts were erroneously not incrementing server \ 
failures meaning the server in use wouldn't rotate.  There was apparently never \ 
a test case for this condition.

  This PR fixes the bug and adds a test case to ensure it behaves properly.

  Support ipv6 link-local servers and %iface syntax (#646)

  Some environments may send router advertisements on a link setting their \ 
link-local (fe80::/10) address as a valid DNS server to the remote system.  This \ 
will cause a DNS entry to be created like `fe80::1%iface`, since all link-local \ 
network interfaces are technically part of the same /10 subnet, it must be told \ 
what interface to send packets through explicitly if there are multiple physical \ 
interfaces.

  This PR adds support for the %iface modifier when setting DNS servers via \ 
`/etc/resolv.conf` as well as via `ares_set_servers_csv()`.

  For MacOS and iOS it is assumed that libresolve will set the `sin6_scope_id` \ 
and should be supported, but my test systems don't seem to read the Router \ 
Advertisement for RDNSS link-local.  Specifying the link-local dns server on \ 
MacOS via adig has been tested and confirmed working.

  For Windows, this is similar to MacOS in that the system doesn't seem to honor \ 
the RDNSS RA, but specifying manually has been tested to work.

  At this point, Android support does not exist.

  Supersedes PR #463

- silence openwatcom warning due to qcache_max_ttl being unsigned

- ares__round_up_pow2() work around bogus warning

  On 32bit systems, a codeblock that would intentionally never
  be executed was emitting a warning.  Rework the code to
  prevent the warning.  More code, no behavior difference, but
  keeps people from complaining about the warning...

- ares_init_options() with invalid options values should unset the option

  Apparently nodejs is relying on the above behavior for legacy reasons.  Add
  sanity checks to the various optmask parameters where it makes sense.

  Nameserver parsing: replace another hand-written parser (#643)

  This replaces the nameserver parsing code with code that use ares__buf_*() in \ 
the name of memory safety.
