* Adapt new interface * Try to write and read rcutils_char_array_t BLOBs in sqlite * Add simple test for arbitrary char ptr * Refactor SqliteWrapper and add tests * Write and read actual timestamp from serialized message and add relative tests * Add SqliteStatementWrapper class and refactor SqliteStorage and SqliteWrapper * Refactor test fixture * ros2GH-50 Assert message content in write_integration_test, and remove TODOs * ros2GH-50 Remove sqlite_storage_plugin unit tests * ros2GH-50 Refactor SqliteStatements and SqliteStorage * ros2GH-50 Fix build after rebase * ros2GH-50 Make has_next() method no more const * ros2GH-52 Extend statement wrapper with a generic bind * ros2GH-50 Refactor after rebase * ros2GH-59 cleanup db interface - Remove virtual on methods as this was added only for unit tests. We decided to use only integration tests for the sqlite plugins. - Changes semantics of SqliteStatement: represents always a prepared statement if not null. - Ensures that a SqliteStatementWrapper cannot be copied and does not publicly expose its sqlite_stmt as this would cause memory corruption. * ros2GH-59 Introduce general read interface for sqlite statements - Uses a std::tuple for row data - Exposes an iterator interface for the query result * ros2GH-59 Cleanup: remove unused files * ros2GH-59 make sqlite interface fluent * ros2GH-59 move creation of serialized message to rosbag2_storage This is not storage plugin specific but will be needed by most (if not all) plugins. * Change rcutil_char_array_t to rmw_serialized_message_t in subscriber * Remove debugging output in test

Currently the
rosbag2layer provides only reader, writer, and info.This interface shall be enhanced to also offer the possibility to read messages from a bag and potentially modify them and store the modified data in the original bag.
