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.

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

meta: fix is_compatible/constructible traits (#3020)
The previous version relied on the existence of an 'iterator' type.

As mentioned in comments, this is not the proper way to do it and
causes issues with certain types (e.g. views from range-v3).

Add a 'is_range' trait that properly detects the return type of
'begin'/'end', and use it in instead.
