gegl-parallel provides various parallel algorithms. Currently, this is limited to the gegl_parallel_distribute() family of functions, which distribute work across multiple threads, migrated from GIMP. The following commits use these functions to replace the various thread-pools we use to auto-parallelize operations with simpler code, fixing potential dealocks as a result of nested operation processing, as in bug #790810, along the way. Since gegl-parallel is public API, it also eases manual parallelization of operations, inside and outside of GEGL.
