Changes to ACE

. Added a new, optional argument named ipv6_only to:
  If ipv6_only is 0/false (the default) the socket will accept
  both IPv6 and IPv4 connections/datagrams. If ipv6_only is
  1/true the socket will only accept IPv6.
  This behavior only applies when ACE_HAS_IPV6 is true and the
  local-side IP address is the generic localhost IP address.

. Integrated some changes from XSC into XML Utils

. Enable ACE_HAS_CPP11 when we have clang with C++11 enabled

. Added support for cross compiling using MinGW on a Linux host

. Added support for FreeBSD 11

. Fixed issue ACE_Singleton was broken after ACE::fini, ACE::init
(GitHub #554)

Changes to TAO

. TAO_IDL parses and discards IDLv4 annotations (applying, not defining)

. Fixed Bug 1220 as it applies to the SHMIOP transport.
