boost: updated to 1.67.0

Version 1.67.0:
New Libraries:
- Contract: Contract programming for C++.
- HOF: Higher-order functions for C++.

Updated Libraries:
- Asio:
Added missing const qualifier to basic_socket_acceptor::get_option.
Worked around a parsing error that occurs with some versions of gcc.
Fixed broken code samples in tutorial.
Added new experimental features. (Note that "experimental" features \ 
may be changed without notice in subsequent releases.)
Added experimental::detached completion token.
Added experimental::redirect_error completion token.
Added experimental::co_spawn facility for integration with the coroutines \ 
technical specification.
Updated timeout examples to use latest features.
Used asio::steady_timer rather than asio::deadline_timer.
Used asio::dynamic_buffer rather than asio::streambuf.
Used timed asio::io_context::run_for() function for blocking clients.
Added example showing a custom completion token for blocking with timeouts.
Fixed unit tests to compile when BOOST_ASIO_NO_DEPRECATED is defined.
Changed socket iostreams to use chrono by default, to fix compatibility with the \ 
Networking TS. Define BOOST_ASIO_USE_BOOST_DATE_TIME_FOR_SOCKET_IOSTREAM to \ 
enable the old Boost.Date_Time interface in basic_socket_streambuf and \ 
basic_socket_iostream.
Updated examples to use chrono rather than Boost.Date_Time.
Fixed an incorrect member function detector in the is_dynamic_buffer trait.
Fixed an async_result incompatibility with deprecated handler_type.
Added a missing move optimisation in the SSL stream implementation.
Fixed incorrect basic_resolver_results::value_type typedef.
Fixed a compile error with some OpenSSL versions when SSL_OP_NO_COMPRESSION is \ 
defined.
Changed add_certificate_authority to process multiple certificates in a bundle.
Eliminated deprecation warning with MSVC by using std::invoke_result rather than \ 
std::result_of.
Changed to use std::string_view for C++17 or later, and \ 
std::experimental::string_view for C++14. Define the preprocessor macro \ 
BOOST_ASIO_DISABLE_STD_STRING_VIEW to force the use of \ 
std::experimental::string_view (assuming it is available) when compiling in \ 
C++17 mode.
Ensured DynamicBuffer template arguments are decayed before using in enable_if tests.
Changed documentation to distinguish legacy completion handlers (which are still \ 
required to be CopyConstructible) from new MoveConstructible handlers.
Suppressed a discarded return value warning in the buffer debugging support.
Fixed basic_yield_context to work with completion signatures containing \ 
reference parameters.
Ensured that stackful coroutines launched using spawn() correctly store decayed \ 
copies of their function and handler arguments.
Fixed some compatibility issues with Android.
Added cross-compilation support to Jamfiles.
Fixed some minor portability issues in examples.

- Atomic:
Breaking change: Changed the result of the (op)_and_test operations added in \ 
Boost 1.66 to the opposite - the functions now return true if the operation \ 
result is non-zero. This is consistent with other test methods in Boost.Atomic \ 
and the C++ standard library. Users can define \ 
BOOST_ATOMIC_DETAIL_HIGHLIGHT_OP_AND_TEST when compiling their code to emit \ 
warnings on every use of the changed functions. This way users can locate the \ 
code that needs to be updated.
Update for C++2a. On C++11 compilers that support scoped enums, the memory_order \ 
enumeration is now scoped and contains constants with shorter names like \ 
acquire, release or seq_cst (i.e. users can use memory_order::acquire instead of \ 
memory_order_acquire). The old constants are also provided for backward \ 
compatibility. (P0439R0)
Update for C++2a. Added experimental support for atomic operations on floating \ 
point types. In addition to general operations, add, sub, negate operations and \ 
their fetch_(op) and opaque_(op) versions are supported. Lock-free property can \ 
be tested with the new macros BOOST_ATOMIC_FLOAT/DOUBLE/LONG_DOUBLE_LOCK_FREE. \ 
The support for floating point types is optional and can be disabled by defining \ 
BOOST_ATOMIC_NO_FLOATING_POINT. (P0020R6)
Added new experimental operations:
negate_and_test and complement_and_test which perform negation or bitwise \ 
complement and return true if the result is not zero.
add, sub, negate, bitwise_and, bitwise_or, bitwise_xor, bitwise_complement \ 
operations which perform the operation and return its result.
For generic atomic<T> specialization, the default constructor is now \ 
trivial if T's default constructor is.
The internal implementation of atomic<T> has been updated to avoid \ 
undefined behavior that stems from signed integer overflows. As required by the \ 
C++ standard, the library uses two's complement representation of signed \ 
integers internally and accroding rules of overflow. Currently, the library \ 
requires the native signed integer types to also use two's complement \ 
representation (but no defined overflow semantics).
Improved Clang support. In particular, fixed DCAS not being lock-free and fixed \ 
possible incorrect code generated on 32-bit x86.
Improved MinGW support. For gcc versions up to 4.6, fixed compilation of DCAS on x86.
In x86 PIE code, asm blocks now preserve ebx value.

- Beast:
This version fixes significant defects in websocket::stream which can lead to \ 
asserts or undefined behavior. Users are encouraged to update to the latest \ 
Boost release.
For a complete list of changes, please view the official Release Notes.

- ContainerHash:
Extracted from the functional module to break a dependency cycle.
Moved headers to new location to reflect name change, the old include paths will \ 
still work.
Added support for std::string_view, std::error_code, std::error_condition, \ 
std::optional, std::variant, std::monostate where available.
Added explicit support for vector<bool>, so that it will work with libc++.
More detail in the library change log.

- Context:
fix i386/macho routines to correctly return transfer_t in EAX/EDX
__sanitizer_finish_switch_fiber should be called directly after context switch
Clang on Windows : error: No best alternative for libs/context/build/asm_sources
fixing C2492 for execution_context (v1)
known bug: including all.hpp + <context-impl>ucontext/winfib causes error \ 
'forced_unwind: is not a member of boost::context::detail'

allows you to:
* create child processes
* setup streams for child processes
* communicate with child processes through streams (synchronously or asynchronously)
* wait for processes to exit (synchronously or asynchronously)
* terminate processes

Log message:
Changes 1.63.0:

Atomic:

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

Context:
* 11687 Xcode (Apple clang) and thread_local
* 12114 context does not preserve fpu context on ios arm64 devices (fixed for \ 
other architecturs too)

Move:
* Improved experimental adaptive sort algorithm performance
* Activate BOOST_MOVE_FORCEINLINE

Optional:
* Added two new in-place constructors. They work similarly to emplace() \ 
functions: they initialize the contained value by perfect-forwarding the \ 
obtained arguments. One constructor always initializes the contained value, the \ 
other based on a boolean condition.
* Syntax o = {} now correctly un-initializes an optional, just like in std::optional.
* Fixed optional<optional<T>&> initialization. (12203)

* Use the hint iterator in emplace_hint.
* Fixed some warnings.

Log message:
Changes 1.62.0:
New Libraries
-------------
Fiber:
* Framework for userland-threads/fibers, from Oliver Kowalke.
QVM:
* Boost QVM is a generic library for working with quaternions, vectors and \ 
matrices of static size with the emphasis on 2, 3 and 4-dimensional operations \ 
needed in graphics, video games and simulation applications, from Emil \ 
Dotchevski.

Updated Libraries
-----------------
Atomic:
* Improved support for Oracle Studio and SPARC. The library now provides native \ 
atomic operations on SPARCv8+.

Chrono:
* 11330 boost::chrono::duration default constructor doesn't initialize rep_
* 11618 Chrono IO V2 doc ios_state.hpp does not exist
* 11631 boost chrono io v2 does not let you support custom clocks

Circular Buffer:
* Debug implementation is no longer used by default in debug mode. Debug \ 
implementation does not have the same thread safety guarantees as the normal \ 
(release) implementation or other containers. As a result of this change \ 
BOOST_CB_DISABLE_DEBUG macro is no longer used. BOOST_CB_ENABLE_DEBUG=1 should \ 
be defined instead to enable debug support.

Container:
* Fixed bugs:
Trac 9481: "Minor comment typo in Boost.Container".
Trac 9689: "Add piecewise_construct to boost::container".
Trac 11170: "Doc slip for index_of".

on a flat_multiset with a non-default sort order".
Trac 12117: "flat_set constructor with ordered_unique_range".
Trac 12177: "vector::priv_merge uses unqualified uintptr_t".
Trac 12183: "GCC 6.1 thinks boost::container::string violates strict \ 
aliasing".
Trac 12256: "set<std::pair<int,int>>::insert cause compilation \ 
error in debug configuration in Visual Studio 2012".
Trac 12273: "static_vector max_size() and capacity() should be constant \ 
expressions". Added constant static_vector<>::static_capacity to use \ 
the configured capacity in constant expressions.
Trac 12286: "PMR flat_map from Boost Container does not compile".

constant_time_size<false>

Lexical Cast:
* Fix incorrect static assertion 11759

Log:
* New features:
Added new tools for inter-process logging on a local machine. The implementation \ 
includes a resource name wrapper, an inter-process message queue and a sink \ 
backend.
Added a new character decorator called max_size_decor. The new decorator allows \ 
to limit the output of its adopted formatter up to the specified length.
* Bug fixes:
Fixed that logging streams could retain formatting settings across different log \ 
records. (12178)
See changelog for more details.

Math:
* New Features:

* New features
dataset driven test-cases have now a unique name and all sample tests of a \ 
dataset live inside the same test suite
Boost.test learned a new command line switch, --logger for setting a test logger \ 
as well as its parameter in one command
Boost.test learned to have several loggers at the same time, each of which \ 
having their own log level and output stream
Boost.test learned a new logger, JUNIT, that is able to output Junit/xUnit \ 
compatible streams
It is now possible to specify several test filters through the environment \ 
variable BOOST_TEST_RUN_FILTERS
* Bug fixes

TypeIndex:
* ctti_type_index was made constexpr in C++14. Now it is possible to retrieve \ 
actual name of the type as const char* at compile time. So we can do a lot of \ 
interesting things at compile time: check namespace of a type, sort types \ 
according to their lexical representation, check that type is a template type \ 
and so on... A few examples were provided.
* Fixed issue with noexcept on MSVC in type names and issue with space in type \ 
name (pulled from klemens-morgenstern/develop)
* Fixed typos pull-request 7

* Variant constructors and assignment operators now do not participate in \ 
overload resolutions if variant can not hold the input type 5871, 11602
* Fixed the issue with implicit conversion operator in C++11 8555
* Fixed comparisons when variant holds non-const reference 11751
* Fixed noexcept for variant's move-assignment 11696

Changes 1.61.0:
New Libraries:
--------------
Compute:
  Parallel/GPU-computing library
DLL:
  Library for comfortable work with DLL and DSO. Library provides a portable \ 
across platforms way to:
* load libraries
* import any native functions and variables
* make alias names for C++ mangled functions and symbols
* query libraries for sections and exported symbols
* self loading and self querying
* getting program and module location by exported symbol
Hana:
  A modern C++ metaprogramming library. It provides high level algorithms to \

a natural syntax, provides tools to introspect user-defined types and much more.
  Metaparse:
A library for generating compile time parsers parsing embedded DSL code as part \ 
of the C++ compilation process. The library is similar to Spirit, however while \ 
parsers built with Spirit parse at run-time, parsers built with Metaparse parse \ 
at compile-time.
