These are not usable by plug-ins anymore which should store their data between runs as arguments or aux arguments (in case of values which should be stored from one run to another but are not really usable for non-interactive scripts). These are per-plug-in (not polluting the whole process space with just random strings as identifiers which could be used by other plug-ins) and even survive restarts of GIMP. I still keep these functions, but only internally, as they are used to store settings of GimpAspectPreview, GimpDrawablePreview and GimpZoomPreview across plug-in runs. Still I changed their API to set and return a GBytes directly (mimicking the private PDB functions' API). Also I remove gimp_pdb_get_data_size() which is useless when exchanging GBytes directly. Note that the 2 functions are still exported in the library, and only not advertized through headers (so they are not really internal, just hidden), on purpose, because we need to call them in libgimpui. So it is still relatively easy for a plug-in to use them. Nevertheless I made clear in the function documentation that these must not be considered public and could end up deleted at any time. Any plug-in still trying to call these takes the risk of having their code relying on unreliable API.
