Abstract the legacy projection code away into a virtual function
of GimpDrawable:
* app/core/gimpdrawable.[ch]: add new virtual function
GimpDrawable::project_region() which projects an area of a
drawable onto a passed in PixelRegion.
* app/core/Makefile.am
* app/core/gimpchannel-project.[ch]
* app/core/gimplayer-project.[ch]: new files which implement it.
* app/core/gimpchannel.c
* app/core/gimplayer.c: hook it in.
* app/core/gimpprojection-construct.c: get rid all the projection
code moved to above new files and project all drawables in one
loop.
* app/core/gimpprojectable.[ch]: remove the legacy methods
get_colormap() and get_components(), they are not needed any
longer.
* app/core/gimpimage.c: changed accordingly.
