[PATCH v1 0/4] box: JSON preparatory patchset

[Kirill Shcherbatov <kshcherbatov@tarantool.org>]

Preparatory patch set for JSON indexes:
- Implemented a new json_token_path_snprint routine able to print
  JSON path to field by field specified working like cannonical
    snprintf routine
- New json_token_is_leaf helper to test node is JSON tree leaf
- Implemented a new bitmap_majority_test routine to check if the
  passed bitmap a "majorates" bitmap b (test that a contains at
  least all b bits).
- Reworked tuple_init_field_map with required fields bitmap -
  a scallable approach able to work with JSON multilevel fields
  tree.
