* app/plug-in/plug-in.[ch]: changed member
"ProcRec *current_temp_proc" to "GList *temp_proc_recs", a stack
of temporary procedures, just as the "temp_main_loops" member is
supposed to be the stack of main loops for waiting for the
temp_procs' return values.
* app/plug-in/plug-in-run.c (plug_in_temp_run): changed accordingly.
* app/plug-in/plug-in-message.c
* app/plug-in/plug-in-run.c
* libgimp/gimp.c: added #define ENABLE_TEMP_RETURN 1.
Enables return values for temporary procedures. On the libgimp
side, this just enables the code which returns the values, on the
app side it enables per-plug-in stacks of proc_recs and main_loops
and a message handler for the GP_TEMP_PROC_RETURN message.
A temp_proc's caller now blocks until the proc is finished.
Fixes bug #50649.
Left the #ifdefs there so it can be easily disabled if things
break. Please play with Script-Fu and test this.
