LWG2170 Aggregates cannot be DefaultConstructible
LWG2016 Allocators must be no-throw swappable

Added missing 'type' x2.
LWG2340 Replacement allocation functions declared as inline
LWG2129 User specializations of std::initializer_list
N4190 Removing auto_ptr, random_shuffle(), And Old <functional> Stuff

Also update [diff.cpp03.utilities] to note that unary_function and
binary_function no longer exist.
N4284 Contiguous Iterators
N4277 TriviallyCopyable reference_wrapper

Added cross-reference to definition of 'trivially copyable'.
N4258 Cleaning‐up noexcept in the Library

[unord.set.overview], [unord.multiset.overview]: Replace meaningless
"Container_move_assign" with the intended "Pred".
N4279 Improved insertion interface for unique-key maps
N3911 TransformationTrait Alias void_t
N4169 A proposal to add invoke function template
N4280 Non-member size() and more
N4089 Safe conversions in unique_ptr<T[]>

Changes to [unique.ptr.runtime.modifiers] removed text that was not present; in
the first paragraph, the only applied change was the insertion of a default
argument. This makes the standard match the described "after" state.

[unique.ptr.runtime] Reorder declarations to consistently order the
converting function and the function taking nullptr_t.
LWG2377 std::align requirements overly strict
LWG2399 shared_ptr's constructor from unique_ptr should be constrained
LWG2400 shared_ptr's get_deleter() should use addressof()
LWG2401 std::function needs more noexcept
LWG2396 underlying_type doesn't say what to do for an incomplete enumeration type
LWG2408 SFINAE-friendly common_type/iterator_traits is missing in C++14

[meta.trans.other] Add missed edit from N3843's "Common wording" that
removes a requirement that common_type always have a member typedef
type. Reprhase this to avoid ambiguity.

Fix a misuse of "comprise" and remove a redundant "Finally" on a
non-final step.

[iterator.traits] Reword changes to read a bit more naturally.
LWG2354 Unnecessary copying when inserting into maps with braced-init syntax
