* Add tests for uncovered code paths
Cover code the test suite did not reach, found from the Coveralls report
of develop and a local coverage run of HEAD:
- dump() of every kind of value below the bound of the recursive descent
(pretty-printed objects, binary values, discarded values, scalars), and
flushes of the escape and write buffers mid-string and mid-binary
- the iterative comparison: objects with different keys, containers that
are a prefix of each other, and elements that cannot be ordered, each
both at the top level and below the nesting bound
- SAX handlers that stop at any event, including the end of a nested
container, in the BSON, CBOR, MessagePack, UBJSON and BJData readers
- from_bson/cbor/msgpack/ubjson/bjdata returning a discarded value
through the iterator and pointer overloads
- JSON Patch, diff, merge_patch and update(..., true) on ordered_json
- smaller gaps: get_allocator(), to_ubjson/to_bjdata into a string,
value() with an unresolvable JSON pointer, integer/float comparison
below the integer range and with negative fractions, conversion to a
custom binary type, std::formatter::parse on a spec without '}',
unescape() of a lone '~', and the callback parser's start_array()

* Cover more paths that were thought unreachable
- parse_float_fast() declining malformed or inexact input, called
directly since the lexer only passes well-formed numbers to it
- a UTF-16 high surrogate followed by a unit above the low surrogates
- self-assignment of a const_iterator
- a truncated CBOR string read through non-contiguous iterators
- serializing a long double under the de_DE locale, which undoes the
locale's decimal point and thousands separator
- values read from a binary format carrying no diagnostic positions,
with and without a parser callback

* Fix the CI failures of the new coverage tests
- declare the self-assignment reference const (misc-const-correctness)
- expect the (/path) prefix that JSON_DIAGNOSTICS adds to the messages
of the failing ordered_json patch operations

* Expect the byte range JSON_DIAGNOSTIC_POSITIONS adds to the patch errors

* Build the expected dump of the nested-object test with +=
clang-tidy (performance-inefficient-string-concatenation) reported the
chain of operator+ calls that assembled the expected indented output.

* Compare the BJData and UBJSON test outputs byte by byte
Building a std::string from the byte vector converts each byte
implicitly, which -fsanitize=integer reports for bytes of 0x80 and
above (ci_test_clang_sanitizer).

---------
Signed-off-by: Niels Lohmann <mail@nlohmann.me>
* Reimplement value() access functions
* Merges the 'const char *' with the 'ValueType &&' overloads.
* Fixes ambiguities when default value is 0.
* Fixes 'no matching function' error when specifying ValueType template
parameter.
* Fixes incorrect template parameter order in previous overloads.
* Add additional value() tests
* Make JSON_MultipleHeaders visible to unit tests
Define the macro JSON_TEST_USING_MULTIPLE_HEADERS to 0/1 depending on
JSON_MultipleHeaders.
* Add type_traits unit test
* Update documentation
* Move UDLs into nlohmann::literals::json_literals namespace
* Add 'using namespace' to unit tests
* Add 'using namespace' to examples
* Add 'using namespace' to README
* Move UDL mkdocs pages out of basic_json/
* Update documentation
* Update docset index
* Add JSON_GlobalUDLs CMake option
* Add unit test
* Build examples without global UDLs
* Add CI target
* 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
