* app/base/gimphistogram.[ch]: add refcounting and replace free()
API by ref() and unref().
* app/core/gimpdrawable-equalize.c
* app/core/gimpdrawable-levels.c
* app/widgets/gimphistogrameditor.c
* tools/pdbgen/pdb/color.pdb: replace calls to
gimp_histogram_free() by gimp_histogram_unref().
* app/pdb/color_cmds.c: regenerated.
* app/widgets/gimphistogramview.c: reference the histograms so we
don't need the widget's users to keep them around while the widget
exists.
* app/tools/gimpcurvestool.[ch]: remove the histogram from the
tool struct and just create one locally to set it on the histogram
view widget.
Unrelated:
* app/tools/gimplevelstool.[ch]
* app/tools/gimpthresholdtool.[ch]: renamed "hist" members to
"histogram" plus some cleanup.
