watt32 compilation fix

  the easy interface was used.

expressions

Added another VS10 version string

fix line break

removed usage of 's6_addr', fixing compilation issue triggered with no
longer using 'in6_addr' but only our 'ares_in6_addr' struct

Added IPv6 name servers support

Constantine Sapuntzakis detected and fixed a double free in builds done
with threaded resolver enabled (Windows default configuration) that would
get triggered when a curl handle is closed while doing DNS resolution.

Added SIZEOF_INT and SIZEOF_SHORT definitions for VMS configuration file

CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION more consistent

  ran into some issues with the GSSAPI tests in configure.ac. The tests first
  try to determine the include dirs and libs and set CPPFLAGS and LIBS
  accordingly. It then checks for the headers and finally sets LIBS a second
  time, causing the libs to be included twice. The first setting of LIBS seems
  redundant and should be left out, since the first part is otherwise just
  about finding headers.

  My second issue is that 'krb5-config --libs gssapi' on Darwin is less than
  useless and returns junk that, while it happens to work with gcc, causes
  clang to choke. For example, --libs returns $CFLAGS along with the libs,
  which is really retarded. Simply setting 'LIBS="$LIBS -lgssapi_krb5
  -lresolv"' on Darwin is sufficient.

  makes sure that when using sub-second timeouts, there's no final bad 1000ms
  wait. Previously, a sub-second timeout would often make the elapsed time end
  up the time rounded up to the nearest second (e.g. 1s for 200ms timeout)

  CURLOPT_CERTINFO feature leaked memory due to a missing OpenSSL function
  call. He provided the patch to fix it too.

  poll() function it doesn't quite work the way we want it so we must disable
  it, and he also provided a patch for it.

  the global timeout if set. Also, as was reported in the bug report #2956437
  by Ryan Chan, the time stamp to use as basis for the per command timeout was
  not set properly in the DONE phase for FTP (and not for SMTP) so I fixed
  that just now. This was a regression compared to 7.19.7 due to the
  conversion of FTP code over to the generic pingpong concepts.

  OpenSSL based SSL handshaking even though the multi interface was used and
  there was no good reason for it.
