* Add versioned inline namespace
Add a versioned inline namespace to prevent ABI issues when linking code
using multiple library versions.

_ldvcmp suffix if JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON is enabled.
* Move ABI-affecting macros into abi_macros.hpp
* Move std_fs namespace definition into std_fs.hpp

* Add operator<< for json_pointer
* Deprecate json_pointer::operator string_t()
* Update documentation
* Move operator<<(basic_json) example
* Add example
* Add mkdocs-redirects

* Use std::vector::insert method instead of std::copy in output_vector_adapter::write_characters
This change increases a lot the performance when writing lots of binary data.
* Add overloads for more key types to ordered_map
Add overloads to accept additional key types defined by type trait
detail::is_usable_as_key_type to ordered_map.
The same key types that can be used with json can now also be used with
ordered_json.
* Fix ordered_map::erase(first, last) with first == last
* Modify element access unit test to also test ordered_json
* Use `std::iterator_traits` to extract `iterator_category`
In third-party STL implementations, `array_t::iterator` might be a pointer (e.g., `vector` in [EASTL](https://github.com/electronicarts/EASTL)) rather than a class, in which case directly using `array_t::iterator::iterator_category` is invalid. This commit fixes it with `std::iterator_traits`, which handles pointers correctly.

Certain lines are unreachable in 64bit builds.

type of its parameter. Assert that both basic_json values are of the
same value type after conversion.

* 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.
