- Use VidMode extension to determine the display dimensions more accurately when enabling full screen mode (fixes #534, should fix Debian #290392)
- Move view port and cursor to a sane position
- Check for VidMode extensions (libXxf86vm)

    because some Xv drivers do not necessarily pad video at 16 bytes.

- Unicode file names fixes

- getcwd() unicode fix

skins2 and galaktos remain as I'm not sure how they (don't?) handle
encodings.

http interface URL were purposedly not made to use Unicode. I'm open to
suggestions on that one.

 * doc/skins/skins2-howto.xml: Updated doc

- fix load/save of configuration and creation of configuration directory (refs #528)

Re-enabled i420_yuy2_mmx on Darwin/x86.

   You can use the following actions in the XML file:
    - dvd.nextTitle()
    - dvd.previousTitle()
    - dvd.nextChapter()
    - dvd.previousChapter()
    - dvd.rootMenu()

  (one must use stat() rather than lstat() to obtain the size of a file's content!)
- Use UTF-8 wrappers (refs #528)

- FromLocaleDup() returns a string to be freed with free() instead of LocaleFree()

 nor pkg-config
