C++14 implementation status


We should add a C++14 status table to the manual but in the meantime
here's a quick summary of the library status.

These are done:

N3669 Fixing constexpr member functions without const
N3668 exchange() utility function
N3670 Wording for Addressing Tuples by Type
N3656 make_unique
N3462 std::result_of and SFINAE
N3545 An Incremental Improvement to integral_constant
N3642 User-defined Literals for Standard Library Types
N3671 Making non-modifying sequence operations more robust
N3654 Quoted Strings Library Proposal (when Ed commits it)

I think these are already done, but need to check:

N3471 Constexpr Library Additions: utilities
N3469 Constexpr Library Additions: chrono
N3470 Constexpr Library Additions: containers

I've implemented these but need to write tests:

N3658 Compile-time integer sequences
N3659 Shared Locking in C++

I'm working on:

N3421 Making Operator Functors greater<>
N3657 Adding heterogeneous comparison lookup to associative containers

These ones are missing:

N3672 A proposal to add a utility class to represent optional objects
N3655 TransformationTraits Redux
N3662 C++ Dynamic Arrays
N3644 Null Forward Iterators

The traits one is simple but a bit tedious and the iterators one
probably only affects debug mode, but the other two are substantial
pieces of work.  Is anyone planning on working on <optional> or
<dynarray> yet?

There are also some LWG issues from the last couple of meetings,
including vector<bool>::emplace, std::cbegin/std::cend,
allocator_traits::max_size(), which I have fixes for in my Git tree.
