d760a316e9 Make config_props() show conversion information before to create the
swscale context.

This makes eventual warnings issued in case of swscale context
creation failure to be shown after the conversion information rather
than before, which is slightly less confusing.

3748b2b8e8 Fix leak in avfilter_graph_add_filter().
In case of reallocation failure the pointer to the original filter
array was lost. The correct behavior seems to just keep the old array

5bb5c1dc86 Add AVFilterPicRef.pos field and make libavfilter propagate stream
byte position information, as stored in the pkt.pos, through the
filterchain.

Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.

ec7ab610d5 Extend the slice filter to make it issue slice height values randomly
choosen between 8 and 32 when the supplied parameter is the string
"random".

This is useful for testing the slice support, but it is not supposed
to be used for other purposes and this interface may change in the
future, thus it is not documented.

The randomization algorithm adopted is the standard Numerical Recipes
LCG.
