ObjectBox C and C++ v0.10.0

C++ API queries and model classes for more feature-rich generated code.
C-API cleanup & docs updates, including the following changes (some of them breaking, mostly due to renames):

Misc

• new property type: DateNano for datetime with nanosecond precision
• new store options obx_opt_*()
  • validate_on_open - to validate the database during openining
  • put_padding_mode - configure the padding used by your flatbuffers implementation
  • use_previous_commit - roll-back the database to the previously committed version
  • read_only - open the database in the read only mode
  • debug_flags - configure debug logging

Cursor

• remove obx_cursor2(), use obx_cursor() in combination with obx_store_entity_id()
• rename obx_cursor_put_mode() to obx_cursor_put4()
• obx_cursor_put() drops the last parameter checkForPreviousValue and introduced a complementary obx_cursor_put_new()
• remove obx_cursor_put_padded()
• rename obx_cursor_backlink_bytes() to obx_cursor_backlinks()
• rename obx_cursor_ts_limits() to obx_cursor_ts_min_max()
• rename obx_cursor_ts_limits_range() to obx_cursor_ts_min_max_range()

Box

• rename obx_box_put() to obx_box_put5()
• rename obx_box_put_object() to obx_box_put_object4()
• change obx_box_put_many to fail when any of the individual inserts/updates fails and new obx_box_put_many5() to override this behavior
• new obx_box_store() to get access to OBX_store* owning the given box
• new obx_box_insert() obx_box_update() for for insert and update semantics, same as put mode arg in obx_box_put5()
• new obx_box_put() without a mode argument (defaults to PUT)
• new obx_box_put_object() without a mode argument (defaults to PUT)
• new obx_box_ts_min_max() for time-series databases
• new obx_box_ts_min_max_range() for time-series databases

Async

• rename obx_async_put_mode() to obx_async_put5()
• rename obx_async_id_put() to obx_async_put_object()
• rename obx_async_id_insert() to obx_async_insert_object()

Query builder

• obx_qb_{type}{operation}() function naming changes to obx_qb{operation}_{type}(), e.g. obx_qb_int_equal() becomes obx_qb_equals_int()
• obx_qb_{operation}_{type}() functions taking multiple arguments have an "s" at the end, indicating plural, e.g. obx_qb_in_int64s()
• operation equal becomes equals, greater becomes greater_than, less becomes less_than
• obx_qb_greater_than_string() drops with_equal argument in favor of the new obx_qb_greater_or_equal_string() function
• obx_qb_less_than_string() drops with_equal argument in favor of the new obx_qb_less_or_equal_string() function
• change obx_qb_in_strings() argument const char* values[] changes to const char* const values[],
  i.e. const array of const char pointers
• obx_qb_greater_than_bytes() drops with_equal argument in favor of the new obx_qb_greater_or_equal_bytes() function
• obx_qb_less_than_bytes() drops with_equal argument in favor of the new obx_qb_less_or_equal_bytes() function

Query

Limit and offset are now part of the query state instead of function arguments, therefore:

• new obx_query_offset() and obx_query_limit() set persistent offset/limit for all future calls to other query functions
• obx_query_find(), obx_query_visit(), obx_query_find_ids(), as well as the cursor alternatives,
  all drop offset and limit arguments
• note: some query functions, such as count/remove don't support non-zero offset/limit yet.
• obx_query_{type}param() function naming changes to obx_query_param{type}(), e.g. obx_query_string_param()
  becomes obx_query_param_string() or obx_query_param_strings() for the plural variant
• obx_query_{type}param_alias() function naming changes to obx_query_param_alias{type}(), e.g. obx_query_string_param_alias()
  becomes obx_query_param_alias_string()
• obx_query_param_strings() and obx_query_param_alias_strings() argument const char* values[]
  changes to const char* const values[], i.e. const array of const char pointers
• obx_query_prop_{type}find() function naming changes to obx_query_prop_find{type}s(), with an "s" indicating the return
  type is plural, e.g. obx_query_prop_find_strings
• remove deprecated obx_query_prop_distinct_string()

ObjectBox C/C++ 0.9.1

• C++ interface improvements:
  • "Box::getOptional()" overloads returning std::optional
  • "Box::put()" overloads taking vectors of std::unique_ptr and std::optional
  • Query methods: find(), findIds(), count(), remove(), ...
  • Ensure double-free can't happen (added explicit copy & move constructors)
• Fixed Windows exported symbols - recently added APIs were missing
• New "obx_cursor_put_object4()" overload taking PutMode as an argument
• Make *_close() functions consistently accept nullptr
