preserve tab position and line when reloading renamed editor file (bug #49322) * file-editor-interface.h: tab index as new argument for request_open_file * file-editor.cc (restore_session): session_data now with line number and new file name after rename; (handle_file_remove): store data of file to remove in the struct session_data and append it to the list of all removed/renamed files; (handle_file_renamed): reload all files at desired tab indexes and line numbers that were previously renamed based on data stored in the list of structures; (request_open_file): new argument: desired tab index, also passed to add_file_editor_tab; (add_file_editor_tab): new argument: desired tab index (handle_dir_remove): use list of session_data structures to store data of removed/renamed files in a directory; * file-editor.h: extended session data by new_file_name and line, request_open_file and add_file_editor_tab with tab index as additional argument, list of session_data structures instead of list of strings for the file data
