Support new libnsgif by adding bitmap flag BITMAP_ABGR.

This tells big endian systems that the data is in ABGR instead of RGBA.
It should be ignored on little endian systems!
Add support in Amiga platform code.

-> All platform code that could be compiled for big endian systems will need
   to be updated to recognise BITMAP_ABGR.  This includes GTK and
   Framebuffer frontends.  Both BITMAP_ABGR *and* the endianness of the host
   will most likely need to be checked and the allocated bitmap format
   and/or bitmap plotter changed to handle ABGR component order.
