There were quite a few places where we either had a non-NUL-terminated string or a text Datum which we needed to call escape_json() on. Many of these places required that a temporary string was created due to the fact that escape_json() needs a NUL-terminated cstring. For text types, those first had to be converted to cstring before calling escape_json() on them. Here we introduce two new functions to make escaping JSON more optimal: escape_json_text() can be given a text Datum to append onto the given buffer. This is more optimal as it foregoes the need to convert the text Datum into a cstring. A temporary allocation is only required if the text Datum needs to be detoasted. escape_json_with_len() can be used when the length of the cstring is already known or the given string isn't NUL-terminated. Having this allows various places which were creating a temporary NUL-terminated string to just call escape_json_with_len() without any temporary memory allocations.
