04a2c71d67 Turn off extern templates for most uses. It is causing more problems than it is worth. The extern templates will still be built into the dylib, mainly for ABI stability purposes. And the client can still turn these back on with a #define if desire. This fixes http://llvm.org/bugs/show_bug.cgi?id=17027. However there's no associated test for the test suite because http://llvm.org/bugs/show_bug.cgi?id=17027 needs mismatched dylib and headers to fire.

499cea12bb Debug mode for string. This commit also marks the first time libc++ debug-mode has found a bug (found one in regex). Had to play with extern templates a bit to get this to work since string is heavily used within libc++.dylib.

8b00e6c960 Ok, 3 major changes for debug mode in one commit: 
1.  I had been detecting and trapping iterator == and \!= among iterators
    in different containers as an error.  But the trapping itself is actually
    an error.
    
    Consider:
    
    #include <iostream>
    #include <vector>
    #include <algorithm>

    template <class C>
    void
    display(const C& c)
    {
        std::cout << "{";
        bool first = true;
        for (const auto& x : c)
        {
            if (\!first)
                std::cout << ", ";
            first = false;
            std::cout << x;
        }
        std::cout << "}\n";
    }

    int
    main()
    {
        typedef std::vector<int> V;
        V v1 = {1, 3, 5};
        V v2 = {2, 4, 6};
        display(v1);
        display(v2);
        V::iterator i = std::find(v1.begin(), v1.end(), 1);
        V::iterator j = std::find(v2.begin(), v2.end(), 2);
        if (*i == *j)
            i = j;    // perfectly legal
        // ...
        if (i \!= j)   // the only way to check
            v2.push_back(*i);
        display(v1);
        display(v2);
    }

    It is legal to assign an iterator from one container to another of the
    same type.  This is required to work.  One might want to test whether or
    not such an assignment had been made.  The way one performs such a check
    is using the iterator's ==, \!= operator.  This is a logical and necessary
    function and does not constitute an error.

2.  I had a header circular dependence bug when _LIBCPP_DEBUG2 is defined.
    This caused a problem in several of the libc++ tests.
    Fixed.

3.  There is a serious problem when _LIBCPP_DEBUG2=1 at the moment in that
    std::basic_string is inoperable.  std::basic_string uses __wrap_iterator
    to implement its iterators.  __wrap_iterator has been rigged up in debug
    mode to support vector.  But string hasn't been rigged up yet.  This means
    that one gets false positives when using std::string in debug mode.  I've
    upped std::string's priority in www/debug_mode.html.

e9df0a5c6c Nico Rieck: Currently _MSC_VER and _WIN32 are used to guard code which is 
MSVC-specific, MSVCRT-specific, or Windows-specific. Because Clang can
also define _MSC_VER, and MSVCRT is not necessarily the only C runtime,
these macros should not be used interchangeably.

This patch divides all Windows-related bits into the aforementioned
categories. Two new macros are introduced:

- _LIBCPP_MSVC: Defined when compiling with MSVC. Detected using
  _MSC_VER, excluding Clang.
- _LIBCPP_MSVCRT: Defined when using the Microsoft CRT. This is the default
   when _WIN32 is defined.

This leaves _WIN32 for code using the Windows API.

This also corrects the spelling of _LIBCP_HAS_IS_BASE_OF to _LIBCPP_HAS_IS_BASE_OF.

Nico, please prepare a patch for CREDITS.TXT, thanks.

5f1286f574 Introduce _LIBCPP_STD_VER. This can be set by the client (or the clang driver). Or it will be defaulted. The default is 11 if -std= c++11 or eariler, else it will default to the current year modulo the century. We anticipate it defaulting to 14 for C++14 when the time comes. For now, post-C++11 libcxx implementations should protect themselves with #if _LIBCPP_STD_VER > 11.

74f4da7219 Stephan Tolksdorf: fixes the issue in the <atomic> header and adds corresponding tests. I've used macros to fall back to a user-provided default constructor if _LIBCPP_HAS_NO_DEFAULTED_FUNCTIONS (though I suspect that there won't be many users defining that macro). 
The tests use placement new to check that atomic values get properly zero-initialized. I had to modify the atomic_is_lock_free test, because default initialization of an object of const type 'const A' (aka 'const atomic<int>') requires a user-provided default constructor.

707f318787 Change _LIBCPP_TYPE_VIS to use __type_visibility__(default) instead of __visibility__(default) when available. This change makes just the type_info visible so that types like vectors and strings can be used as exception objects across dylib boundaries even when hidden visibility is specified globally (at the command line), and yet this allows clients to hide the member functions of things like vector and string (with global visibility commands).

866569b8c3 Attempted locale refactoring. _LIBCPP_LOCALE__L_EXTENSIONS now should be defined if one has all of the xxx_l() functions. I've defined this for apple, freebsd and win32. _LIBCPP_HAS_DEFAULTRUNELOCALE should be defined if there is a _DefaultRuneLocale. I've defined this for apple and freebsd. The block of code we're trying to migrate away from is now under #ifdef __linux__. I've tested only on OS X. I hope I haven't broken things too badly elsewhere. Please let me know.

libc++ now mostly works on FreeBSD with libcxxrt and this patch applied to the base system:
