Pavel A. Lebedev cb1e6af53d Add conditional noexcept forwarding from free to member swap functions.

This allows std::is_nothrow_swappable{,_with} to work properly.
This only touches user-facing classes, with the following exceptions:
- map,set: only doc changes (with a drive-by missing semicolon fix),
  detail::tree which they derive from already forwards noexcept for swap.
- flat_set: only doc changes for flat_set and a change for
  detail::flat_tree, which it derives from to get swap.
- static_vector: while this adds the forwarding, member static_vector::swap
  is currently never noexcept, although it could be for noexcept-swappable
  and noexcept-move-constructible elements.
- small_vector: there is no free swap, and member swap is never noexcept,
  although it could be for noexcept-swappable and noexcept-move-
  constructible elements. Swapping small_vectors of exact same type goes
  through std::swap, which seems to get noexcept right, and small_vectors
  of different sizes use swap for boost::container::vector, which fails
  to detect when such swap could be noexcept. This patch doesn't touch
  small_vector.
- scoped_allocator: neither member nor free swap are noexcept, although
  they should be, and all other constructions/assignments/comparisons too,
  as they only forward these operations to underlying allocators, which
  are required to not throw exceptions for them. Only static_vector's
  static_storage_allocator might throw for these and it shouldn't appear
  in scoped_allocator. Unsure of the scope of changes needed or whether it
  is even worth it, this patch doesn't touch scoped_allocator.

README.md

Boost.Container

Boost.Container, part of collection of the Boost C++ Libraries, implements several well-known containers, including STL containers. The aim of the library is to offer advanced features not present in standard containers, to offer the latest standard draft features for compilers that don't comply with the latest C++ standard and to offer useful non-STL containers.

Properties

C++03
Mostly header-only, library compilation is required for few features.
Supports compiler modes without exceptions support (e.g. -fno-exceptions).
