Fix memory leakage in python bindings

The python bindings generated by the groovy code generator contain a reference counting bug which results in a memory leak whenever a std::vector is converted to a python list.  The following member functions are affected:

* xbmcvfs.listdir
* xbmc.Player.getAvailableSubtitleStreams
* xbmc.Player.getAvailableAudioStreams
* xbmcgui.Control.getPosition
* xbmcgui.Dialog.browse
* xbmcgui.Dialog.browseMultiple

The reference counting bug occurs because PyList_Append() increments the reference count of the item, so the caller needs to call Py_DECREF() because it no longer owns the object.

This bug is especially problematic when running the Watchdog Service Addon since it may result in frequent calls to xbmcvfs.listdir, and each call can leak many kilobytes of data when listing directories containing many files.
fixed: Properly handle stacked files for subtitles
vdpau: map/unmap surfaces on every cycle, requested by AMD
vdpau: Improve detection of supported files.

A minor improvement on the detection of whether or not a video will
play. It is a good idea to at least make sure that the video codec
is supported and that the resolution does not exceed the supported
resolution.
