* upgraded libcdio to 0.7.2 (not that it makes much difference :) )

         always defined)

  if this breaks the linux or win32 mozilla plugin then it should be restored.

The playlist works fine again (with ASCII/Latin locale charset).
When in UTF8, it might be a good idea to check for invalid bytes
sequences and replace them with question mark - at the moment
wxWidgets still leave the whole text blank which result in blank
playlist item in the playlist.

(the documentation for wxWidgets 2.5.3 is wrong :
 wxConvCurrent (which does not work) does not point
 to wxConvLibc nor wxConvLocal (which both work))

It is now possible to use wxvlc with non UTF-8 locale.
Previously, any text item with non-ASCII character in it would be
blank.

* modules/stream_out/transcode.c: fixed segfault.
