Implement buffer clipping/dropping using GstSegment.
This provides accurate seeking.

* ext/libpng/gstpngdec.h: Complete rewrite of pngdec. It's now
very nice and handle push/pull based model. if you have filesrc
connected to it, it will do random access to load the png file.
If you have a network source that can't do _getrange, it does
progressive loading through the chain function.
* gst/alpha/gstalphacolor.c: (gst_alpha_color_transform_caps),
(transform_rgb), (transform_bgr): Fix caps negotiation correctly
thanks to Master Wim Taymans ;-)
