mariadb/storage/connect/global.h
Olivier Bertrand dc3a693b70 - Inline MakePtr and MakeOff with OFFSET as size_t
Also add a new member Saved_Size in the Global structure.
  modified:   storage/connect/global.h
  modified:   storage/connect/plugutil.cpp
  modified:   storage/connect/user_connect.cc
  modified:   storage/connect/jsonudf.cpp

- Add session variables json_all_path and default_depth
  modified:   storage/connect/ha_connect.cc
  modified:   storage/connect/mongo.cpp
  modified:   storage/connect/tabjson.cpp
  modified:   storage/connect/tabxml.cpp

- ADD column options JPATH and XPATH
  Work as FIELD_FORMAT but are more readable
  modified:   storage/connect/ha_connect.cc
  modified:   storage/connect/ha_connect.h
  modified:   storage/connect/mysql-test/connect/r/json_java_2.result
  modified:   storage/connect/mysql-test/connect/r/json_java_3.result
  modified:   storage/connect/mysql-test/connect/r/json_mongo_c.result

- Handle negative numbes in the option list
  modified:   storage/connect/ha_connect.cc

- Fix Json parse that could crash the server.
  Was because it could use THROW out of the TRY block.
  Also handle all error by THROW.
  It is now done by a new class JSON.
  modified:   storage/connect/json.cpp
  modified:   storage/connect/json.h

- Add a new UDF function jfile_translate.
  It translate a Json file to pretty = 0.
  Fast because it does not a real parse of the file.
  modified:   storage/connect/jsonudf.cpp
  modified:   storage/connect/jsonudf.h

- Add a now options JSIZE and STRINGIFY to Json tables.
  STRINGIFY makes Objects or Arrays to be returned by their
  json representation instead of by their concatenated values.
  JSIZE allows to specify the LRECL (was 256) defaults to 1024.
  Also fix a bug about locating the sub-table by its path.
