Creates and places the segment manager. This can throw The external memory supplied by the user shall be aligned to the maximum value between alignof(std::max_align_t) and the strictest alignment of any over-aligned type to be built inside that memory.

void swap(basic_managed_external_buffer & other) noexcept;
Swaps the ownership of the managed heap memories managed by *this and other. Never throws.
