lang/seed7: update to 05_20160831

• The Seed7 runtime library has been improved to allow paths longer than PATH_MAX (260) characters under Windows.
• The program sydir7.sd7 has been improved. Now it is avoided to copy a file, when source and destination differ only by date. The option -c has been added. With -c the source is copied and files that are missing in the source are removed from the destination.
• The function readVolumeName in dir_rtl.c has been improved to allow extended length paths (This paths exist under Windows and have a prefix of \\?\ ).
• The functions opendir and wopendir in dir_win.c have been improved to allow paths longer than 260.
• In the library seed7_05.s7i the undocumented function xalloc has been removed.
• The function printArgv has been added to arr_rtl.c to improve the logging.
• The program chkccomp.c has been improved to write settings to always use the directory functions from dir_win.c under Windows.
• The function adjustCwdForShell has been added to cmd_rtl.c. This function sets the current working directory to something acceptable by cmd.exe.
• In stat_win.c the function wstati64 has been renamed to wstati64Ext and improved to call the original stat function, when possible.
• The new file stat_drv.h has been added. In this file a prototype of wstati64Ext is defined when necessary.
• The program wrdepend.c has been improved to work correctly, when the INCLUDE_OPTIONS macro contains newline characters.
