[PATCH v1 0/5] box: JSON preparatory patchset

[Kirill Shcherbatov]

Preparatory patch set for JSON indexes:
- Implemented tuple_validate with tuple_init_field_map.
- Refactored field type/nullability check routines.
- Implemented a new json_token_path_snprint routine able to print
  JSON path to field by field specified working like cannonical
  snprintf routine
- Reworked box error messages to use the json_token_path_snprint
  helper to report field names in error in error messages.
- Reworked tuple_init_field_map with required fields bitmap -
  a scallable approach able to work with JSON multilevel fields
  tree.
