It happend that the previously shown frame was still on screen
while the decoder reused it already and the result was a mixed
picture on screen.
Protection is easy: just keep a reference to previously shown
frame and it cannot be reused by the decoder until a frame
duration has passed which should be sufficient to see the
current frame on screen.
Such referencing has already been implemented although it was
not used for deinterlacing. Therefore it had been disabled to
get an additional frame for decoding in coping with dropped
frames.
The change reenables referencing the previously shown frame.

While disabling for progressive frames was ment to improve DVD
playback, it turned out that many TV broadcasters set this flag
too, although their content is not progressive.
Adding an option allows the user now to enable this feature when
the watched streams make correct use of this flag.
Another option allows to disable bob deinterlacing when a scaled
OSD is on screen. As bobbing adds some noise to horizontal lines
the OSD quality might be improved by enabling this option.

When xine-ui switches to fullscreen mode or back again, it will
change the drawable by sending XINE_GUI_SEND_DRAWABLE_CHANGED.
This may lead to BadDrawable X Errors when the video out thread
is still using the old drawable for drawing.
The changes below block XINE_GUI_SEND_DRAWABLE_CHANGED from
changing the drawable while it is used for drawing.

xine_spudvb_decoder.c has hardcoded frame size (720x576).
While this is fine for most dvb channels, some channels have smaller frame
size (e.g. 544x576) but the dvb subs bitmaps are however still 720 width.
In such case, some right aligned subs appear truncated.
This patch adds a (very basic) function to downscale subs to fit frame width.

Well, seems i've forgot this one ;)

This new patch honors ui.osd.text_palette

Actually, audio_decoder_loop stores audio streams in ascending buffer type
order. So, for example a stream with buffer type BUF_AUDIO_A52|channel_num
will always be stored in audio_track_map array before any mpegaudio stream.
This breaks the stream order known by TS demuxer and so a user can get a52
french audio when selecting "deu" ! Bad again. This patch fixes that.

With current code, ts demuxer stores audio tracks in the order it finds it in
PMT, but doesn't correctly set the buffer type so stream's audio_track_map
may (and often) have a different order and so a user can get german audio
when selecting "ita" ! Bad. This patch fixes that.
It also fixes get_optional_data to return correct spu lang instead of none.
