This patch adds support for thread cancellation on Windows CE. It
emulates missing functions such as WaitForSingleObjectEx, by creating
a cancellation event handle, and forwarding the wait functions to wait
on both the original handles and the cancellation event. The thread can
then be cancelled by triggering the event from another thread.

The colourspace is wrong, but we have no other solutions for now.
Patch by Edouard Gomez, idea modified by David Flynn and merged manually by me.

 It allows to have more complete informations but only on currently
decoded tracks.

 It might not be the cleanest way, but I don't see any other fix with the
current API.
 Feel free to revert if a better fix can be found.
