[PATCH v3 0/3] Implement json path access to tuple fields

[Vladislav Shpilevoy]

Branch: http://github.com/tarantool/tarantool/tree/gh-1285-tuple-field-by-json-icu
Issue: https://github.com/tarantool/tarantool/issues/1285

Tuple field access by JSON path provides fast access to a field and field
internals with no unpacking an entire tuple or even the field into Lua.

This patchset is a first part of JSON introduction into Tarantool core. It
introduces the JSON path parser and tuple internals access by JSON. The next
patchsets will introduce tuple update by JSON - gh-1261, indexing by
JSON - gh-1012.
