Implement support for string_view (attempt no. 3) (#3423)
* Add key_compare member to ordered_map

* Replace == with key_compare in ordered_map

* Expose the actual comparison function used by object_t

nlohmann::ordered_map uses a different comparison function than the one
provided via template parameter.
* Introduce a type trait to detect if object_t has a key_compare member.
* Rename object_comparator_t to default_object_comparator_t.
* Add object_comparator_t to be conditionally defined as
  object_t::key_compare, if available, or default_object_comparator_t
  otherwise.
* Update the documentation accordingly.

* Add type traits to check if a type is usable as object key

Add type trait to check:
* if a type is a specialization of a template.
* if a type is a json_pointer.
* if a type is a basic_json::{const_,}iterator.
* if two types are comparable using a given comparison functor.
* if a type is comparable to basic_json::object_t::key_type.
* if a type has a member type is_transparent.
* if a type is usable as object key.
* if a type has an erase() function accepting a given KeyType.

* Rework basic_json element access to accept more key types

Rework basic_json element access member functions and operators to
accept any type that meets the requirements defined by type trait
detail::is_usable_as_key_type.

Member functions and operators:
* at()
* operator[]
* value()
* erase()
* find()
* count()
* contains()

Update documentation to reflect these changes.

Add unit tests to excercise the new functions using std::string_view.

Restore disabled check for #3070 (except on MSVC) (#3421)
Restore the previously disabled check for regression #3070 on all
compilers but MSVC.

To summarize the issue:
Given namespace fs = std::filesystem.
On MSVC attempting to construct an fs::path from json results in an
ambiguous overload resolution because fs::path can be constructed from
both a std::string as well as another fs::path.
To the best of my knowledge there is no way to fix an ambiguous overload
situation involving a type we do not control and with json implicitly
converting to both std::string and fs::path.

Re-enabling the check where it compiles and keeping it disabled for MSVC
is the best we can do.

Closes #3377 and #3382.

Improve unit testing (Part 1) (#3380)
* Refactor unit test creation

Add functions for creating tests and to supply test- and
standard-specific build settings.

Raises minimum CMake version to 3.13 in test directory.

json_test_add_test_for(
    <file>
    MAIN <main>
    [CXX_STANDARDS <version_number>...] [FORCE])

Given a <file> unit-foo.cpp, produces

    test-foo_cpp<version_number>

if C++ standard <version_number> is supported by the compiler and
thesource file contains JSON_HAS_CPP_<version_number>.  Use FORCE to
create the test regardless of the file containing
JSON_HAS_CPP_<version_number>.  Test targets are linked against <main>.
CXX_STANDARDS defaults to "11".

json_test_set_test_options(
    all|<tests>
    [CXX_STANDARDS all|<args>...]
    [COMPILE_DEFINITIONS <args>...]
    [COMPILE_FEATURES <args>...]
    [COMPILE_OPTIONS <args>...]
    [LINK_LIBRARIES <args>...]
    [LINK_OPTIONS <args>...])

Supply test- and standard-specific build settings.
Specify multiple tests using a list e.g., "test-foo;test-bar".

Must be called BEFORE the test is created.

* Use CMAKE_MODULE_PATH

* Don't undef some macros if JSON_TEST_KEEP_MACROS is defined

* Use JSON_TEST_KEEP_MACROS

Incidentally enables the regression tests for #2546 and #3070.

A CHECK_THROWS_WITH_AS in #3070 was disabled which is tracked in #3377
and a line in from_json(..., std_fs::path&) was marked with LCOV_EXCL_LINE.

* Add three-way comparison feature test macro

* Disable broken comparison if JSON_HAS_THREE_WAY_COMPARISON

* Fix redefinition of inline constexpr statics

Redelcaration of inline constexpr static data members in namespace scope
was deprecated in C++17. Fixes -Werror=deprecated compilation failures.

* Fix more test build failures due to missing noexcept

* CI: update cmake_flags test to use CMake 3.13 in test directory

Also change default for JSON_BuildTests option to depend on CMake
version.

* CI: turn *_CXXFLAGS into CMake lists

* CI: use JSON_TestStandards to set CXX_STANDARD

* CI: pass extra CXXFLAGS to standards tests

Make iterator operator++/--(int) equality-preserving (#3332)
Commit f28fc22 introduced const qualifiers on post-(inc-/dec-)rement
operators of iterators. These qualifiers prevent the use of basic_json
in place of std::ranges::range, which requires the post-increment
operator to be equality-preserving.

These changes appear to be the result of ICC compiler suggestions, and
no further explanation is discernible from the PR discussion (#858).
Further testing revealed, that clang-tidy also suggests adding const to
prevent "accidental mutation of a temporary object".

As an alternative, this commit partially reverts f28fc22, removing all
added const qualifiers from return types and adds lvalue reference
qualifiers to the operator member functions instead.

Unit tests ensure the operators remain equality-preserving and
accidental mutation of temporaries following post-(inc-/dec-)rement is
prohibited.

Fixes #3331.

* 🔧 use proper GCC binary

* 🔧 add more GCC warning flags

* ⚗️ try fix from https://github.com/nlohmann/json/issues/3138#issuecomment-1015562666

* Fix custom allocator test build failures (C++20)

Allocator tests fail to compile in C++20 mode with clang+MS STL due
to missing copy constructors.

* Fix test build failures due to missing noexcept (gcc-12)

* alt_string has multiple member functions that should be marked noexcept.
* nlohmann::ordered_map constructors can be noexcept.

Compilation failures result from the warning flag -Werror=noexcept and
gcc-12.

* Disable broken comparison tests in C++20 mode
