7776ae4191 Use BOOST_GCC, defined in config.hpp only for real (non-Clang-emulated) GCC 
builds, in place of relevant uses of the __GNUC__ macro.

cefbd3014a When defining BOOST_STL_INTERFACES_USE_DEDUCED_THIS=1, require C++23 mode for 
the cases where __cpp_explicit_this_parameter is not defined, but the compiler
is known to support it.  Obviously, even if those compiler support it, it's
not available in older C++ versions.

Fixes #72.

f89646cddf Enable BOOST_STL_INTERFACES_USE_DEDUCED_THIS on Clang 19 and MSVC 19.41 
Clang 19 and MSVC 19.41 both have support for deducing this that is
complete enough to allow the v3 version of this library to work but
not complete enough for the compilers to define
__cpp_explicit_this_parameter. This commit enables the v3 version of
this library on compilers with that version or newer. We make use of
BOOST_CLANG_VERSION here because on AppleClang it should provide the
version of upstream Clang that was used for that release.

1c050d2df5 Add an rvalue-qualified overload of closure::operator(). This makes 
forwarding work properly in cases such as r | foo(std::string("foo")), where
foo is an adaptor.  Without this, the std::string temporary dangles.

d61867d8be GCC 13 reports as ill-formed code that evaluates a concept C more than once 
with the same template parameters, when the value of C changes between the
evaluations.  This is correct, but no other implementation checks this.  Move
all the hidden friends out of the v2::iterator_interface to fix these kinds of
errors.

c022029c27 In C++20 and later, return void from operator++(int), for input_iterators. 
This matches the requirements of the std::input_iterator concept.  This is not
done in earlier C++ versions, because it completely breaks use of input
iterators with the standard algorithms.

21e03e7013 Use the given iterator_concept, but only define iterator_category when 
appropriate to do so.  Appropriateness follows the algorithm for zip_view's
iterator.  See https://eel.is/c++draft/range.zip.transform.iterator#1.

Requested by LEWG reviewers of iterator_interface.

e98536344d Pass an rvalue to emplace_back() in unevaluated contexts that are testing its 
existence.  This is important for containers derived from sequence_container
that constrain emplace_back() itself, and have a move-only value_type.

53448edcdc Add full v2 namespace (C++20) implementation. When building in C++20 mode, 
including with __cpp_lib_concepts defined, the v2 namespace is inlined.
Otherwise, the v1 namespace is inlined.  This allows switching to
concept-constrained templates without changing any user code.
