Re-template json_pointer on string type (#3415) 
* Make exception context optional

Change exception context parameter to pointer and replace context with
nullptr where appropriate.

* Support escaping other string types

* Add string concatenation function

Add variadic concat() function for concatenating char *, char, and
string types.

* Replace string concatenations using + with concat()

* Template json_pointer on string type

Change json_pointer from being templated on basic_json to being
templated on string type.

* Add unit test for #3388

Closes #3388.

* Fix regression test for #2958

* Add backwards compatibility with json_pointer<basic_json>

* Update json_pointer docs

* Allow comparing different json_pointers

* Update version numbers

nlohmann::json_pointer::operator/

// (1)
json_pointer operator/(const json_pointer& lhs, const json_pointer& rhs);

// (2)
json_pointer operator/(const json_pointer& lhs, string_t token);

// (3)
json_pointer operator/(const json_pointer& lhs, std::size_t array_idx);
  1. create a new JSON pointer by appending the right JSON pointer at the end of the left JSON pointer
  2. create a new JSON pointer by appending the unescaped token at the end of the JSON pointer
  3. create a new JSON pointer by appending the array-index-token at the end of the JSON pointer

Parameters

lhs (in)
JSON pointer
rhs (in)
JSON pointer to append
token (in)
reference token to append
array_idx (in)
array index to append

Return value

  1. a new JSON pointer with rhs appended to lhs
  2. a new JSON pointer with unescaped token appended to lhs
  3. a new JSON pointer with array_idx appended to lhs

Complexity

  1. Linear in the length of lhs and rhs.
  2. Linear in the length of lhs.
  3. Linear in the length of lhs.

Examples

??? example

The example shows the usage of `operator/`.
 
```cpp
--8<-- "examples/json_pointer__operator_add_binary.cpp"
```

Output:

```json
--8<-- "examples/json_pointer__operator_add_binary.output"
```

Version history

  1. Added in version 3.6.0.
  2. Added in version 3.6.0. Changed type of token to string_t in version 3.11.0.
  3. Added in version 3.6.0.
