76ddd498e2 dvbsuboverlay: Handle non_modifying_colour_flag correctly in the RLE handlers
The check for when to not memset was checking on an undeterministic 'bits' variable value,
which is only meant to be used inside the loop earlier when it is supposed to check if
clut_index is 1 together with non_mod set, as per spec:

"non_modifying_colour_flag:  If set to '1' this indicates that the CLUT entry value '1'
is a non modifying colour. When the non modifying colour is assigned to an object pixel,
then the pixel of the underlying region background or object shall not be modified. This
can be used to create "transparent holes" in objects."

994156c1b8 dvbsuboverlay: remove unnecessary RGB -> YUV conversion by using YUV palettes
the default CLUTs still use RGB -> YUV conversions since the standard defines
them as RGBA values.

767c29cc2f dvbsuboverlay: use GST_LOG etc. for logging
The dvbsub routines were originally designed as a mini lib with a
log callback (which from the looks of it in our case would always
be called and always assemble the string even with debug output
disabled). Some of these debug statements can probably be removed
or cleaned up some more.

41c82583f5 dvbsuboverlay: Make the new dvb_subtitles_free() accept NULL
Don't crash if dvb_subtitles_free(NULL) gets passed, like most other
*_free functions are happy with.

7e2e52cab8 dvbsuboverlay: Pass page_time_out and pts with the DVBSubtitles structure
Eases holding onto the information in gst plugins side queue of
DVBSubtitles, so we won't need to create yet another temporary struct
to keep the pts and page_time_out too.
And this really logically belongs at the toplevel information set anyway
and in that struct...

aca7237878 dvbsuboverlay: Make the libdvbsub callback handler responsible for memory cleanup
We want to allow queueing of raw region image data in the gst plugin side,
and keep the data around until we pop the item from the queue. So make
the callback handler responsible for memory cleanup, if one is installed.
