Implement strbuffer

String buffer (strbuffer) is an object that resizes automatically when
data is added to it. It was implemented by generalizing the technique
used in json_dumps().
strbuffer: Allocate enough space for value initially
strbuffer_value: Return a read-only pointer rather than duplicating the value
Implement json_load, json_loadf and json_loadfd
Fix a few memory leaks in json_parse_object()
