Preparatory patch set for JSON indexes story.
Implemented JSON tree class is used for organizing JSON tokens
produced by a lexer in a tree-like structure reflecting a JSON
document structure.
Refactored json_lexer class to use index_base to emmit tokens
being ready to insert in JSON tree.
Refactored tuple_format to use the tree JSON class for working
with first-level fields to works with all fields in unified way.
Introduced help routines json_path_validate and json_path_cmp.
The third path "box: manage format fields with JSON tree class"
triggers a bug #3772 that is already on review
kshch/gh-3772-dirty-memory-access. Source branch has
cherry-picked fix.
General information of difference from previous version of
patch-set:
- new patch "make index_base support for json_lexer" allows to
do not carry for LUA index base during token insertion
- significantly improved comments, many minor refactoring
- new consistency assertions, e.g. that no fields attached during
token detach.
- reworked iterators
- _slowpath version for json_tree_lookup to improve performance
for numerical levels
- new tests
- reworked json_path_cmp, introduced json_path_validate
- rebased on up-to-date 2.1 and cherry-picked #3772 fix
