Boost 1.63.0 发布，可移植的 C++ 标准库

Boost 1.63.0 发布了，Boost 库是一个经过千锤百炼、可移植、提供源代码的 C++ 库，作为标准库的后备，是 C++ 标准化进程的发动机之一，由 C++ 标准委员会库工作组成员发起。

部分更新内容：

Atomic:

• Added the static constant atomic<T>::is_always_lock_free for conformance with C++17. The constant indicates that the given specialization always provides lock-free implementation of atomic operations.

• Improved support of Oracle Studio on x86 targets.

Container: Fixed bugs:

• "flat_map fails to compile if included after type_traits is instantiated under gcc".

• "Null reference in pair.hpp triggers runtime warning with -fsanitize=undefined".

• Fix parameter types in copy_move_algo.hpp: iterator_traits::difference_type -> allocator_traits::size_type.

• Avoid -Wunreachable-code in do_allocate().

Context:

• #11687 Xcode (Apple clang) and thread_local

• #12114 context does not preserve fpu context on ios arm64 devices (fixed for other architecturs too)

• #12411 fpu registers not preserved with O2 optimizations in Visual Studio (fixed for other architecturs too)

• #12551 building boost on arm64 causes error: unknown directive

• reduced signatur for ontop-functions

• unit-test for private fcontext-API

• performance-test for ucontext and fcontext fixed
