This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

GeglOperation
* operation names are now prefixed, the ops in GEGL use 'gegl:' as prefix.
* gegl:opacity - combine value and aux mask input when both are available.
* gegl:src-in - deal correctly with extens.
* gegl:path - new op covering the stroke/fill needs of SVG.
* deprecated gegl:shift, the affine familiy of operations now
uses the same fast code paths for integer translations.
GeglBuffer
* Profiling motivated speed ups in data reading/writing.
* Remove left-over swapfiles from dead processes at startup.
GeglNode
* made gegl_node_add_child and gegl_node_remove_child public API.
GeglPath
* Vector path representation infrastructure, supporting poly lines and beziers
by default, the infrastructure allows extensions from applications with
other curve types (smooth curves, spiro curves and others.).
framework.
GEGL provides infrastructure to do demand based cached non destructive
image editing on larger than RAM buffers. Through babl it provides
support for a wide range of color models and pixel storage formats for
input and output.
