(svn r11119) -Codechange: analyze .tar files upon loading, remembering their files and offsets, which speeds up .tar handling with a big factor

-Fix: several win32 .tar support problems
-Fix: better checking of .tar versions and other minor things
-Codechange: don't call fclose() but FioFClose to close a file
