9448dd00b0 Fix warnings from newer clang versions about constexpr member functions 
not being implicitly const in libc++'s <chrono> header.  The warnings
have been introduced because of new language rules recently adopted by
the C++ WG.  More info:

5f5f8832fb Pull in r168610 from upstream libc++: 
When using libc++ headers on FreeBSD, in combination with -std=c++98,
  -ansi or -std=c++03, the long long type is not supported.  So in this
  case, several functions and types, like lldiv_t, strtoll(), are not
  declared.

This should make it possible to use the libc++ headers in c++98 mode.

Note: libc++ is originally designed as a c++0x or higher library, so you
should still take care when using it with c++98 or c++03.

d3c53822e7 Fix two -Wsystem-header warnings in libc++ that were exposed by the new 
ATF import.  These have also been sent upstream.

936e943916 Import libc++ trunk r165949. Among other improvements and bug fixes, 
this has many visibility problems fixed, which should help with
compiling certain ports that exercise C++11 mode (i.e. Firefox).

Also, belatedly add the LICENSE.TXT and accompanying CREDITS.TXT files,
which are referred to in all the source files.

b03f91a837 Import new version of libc++. Among other improvements, this comes with an 
<atomic> header that works with clang 3.1 (and, importantly, the pre-3.1
snapshot currently in head)

Please tests any C++ code you care about with -stdlib=libc++!

7a98470824 Import libc++ / libcxxrt into base. Not build by default yet (use 
MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

To build C++ using libc++, add -stdlib=libc++ to your CXX and LD flags.

Bug reports welcome, bug fixes even more welcome...
