[PATCH v8 0/5] box: Indexes by JSON path

[Kirill Shcherbatov]

Sometimes field data could have complex document structure.
When this structure is consistent across whole document,
you are able to create an index by JSON path.

Changes in version 8:
    - implemented mp_stack class and reworked mp_tuple_field_map_init
      with this new API
    - reworked "specify patch in user-friendly form" as LUA code
    - reworked tuple_field* routines stack to be a little more logical
    - path allocation on region in tuple_format1_can_store_format2_tuples
    - removed max path limit
    - better class members names
    - point code refactoring
