/**
  @file
  json service

  Exports JSON parsing methods for plugins to use.

  Functions of the service:
    json_type - returns the type of the JSON argument,
       and the parsed value if it's scalar (not object or array)

    json_get_array_item - expects JSON array as an argument,
       and returns the type of the element at index `n_item`.
       Returns JSV_NOTHING type if the array is shorter
       than n_item and the actual length of the array in value_len.
       If successful, then `value` up till `value[value_len]` contains the array
       element at the desired index (n_item).

    json_get_object_key - expects JSON object as an argument,
       searches for a key in the object, return it's type and stores its value in `value`.
       JSV_NOTHING if no such key found, the number of keys
       in v_len.

    json_get_object_nkey - expects JSON object as an argument.
      finds n_key's key in the object, returns it's name, type and value.
      JSV_NOTHING if object has less keys than n_key.
