Command lists

To facilitate faster adding of files etc. you can pass a list of commands all at once using a command list. The command list begins with command_list_begin or command_list_ok_begin and ends with command_list_end.

It does not execute any commands until the list has ended. The return value is whatever the return for a list of commands is. On success for all commands, OK is returned. If a command fails, no more commands are executed and the appropriate ACK error is returned. If command_list_ok_begin is used, list_OK is returned for each successful command executed in the command list.
