Add a new "Swap compression" option to the preferences, allowing
explicit control over the tile-swap compression algorithm.
Previously, control over swap compression was only possible through
GEGL command-line options/environment variables. Since the GEGL
API to list all available compression algorithms is still private
for now, we currently only list the three predefined compression
levels -- "best performance" (the default), "balanced", and "best
compression" -- and a "none" option, to disable compression
altogether. Selecting a custom compression algorithm is possible
by entering its name manually.

Move swap/cache and temporary files out the GIMP user config dir:
libgimpbase: add gimp_cache_directory() and gimp_temp_directory()
which return the new default values inside XDG_CACHE_HOME and the
system temp directory. Like all directories from gimpenv.[ch] the
values can be overridden by environment variables. Improve API docs
for all functions returning directories.
Add new config file substitutions ${gimp_cache_dir} and
${gimp_temp_dir}.
Document all the new stuff in the gimp and gimprc manpages.
app: default "swap-path" and "temp-path" to the new config file
substitutions. On startup and config changes, make sure that the swap
and temp directories actually exist.
In the preferences dialog, add reset buttons to all file path pages.

... "threads" property.
Actually there is no need of having a public GEGL_MAX_THREADS as written
in the previous commit. We can just retrieve the max for a GObject
property.
Raise GIMP_MAX_NUM_THREADS to 64, following the changes in GEGL (see
GEGL commits 6d128ac and f26acbb). This is still considered unstable and
to be used at one's own risk (cf. GIMP commit 1f5739d) but at least, it
could allow discovering and fixing bugs.
It would be nice if GEGL_MAX_THREADS could be public so that to not have
to edit this by hand at each change.
- enable the setting code in gimp-gegl.c again
- but set the default to one thread in GimpGeglConfig, with a CPP warning
- rename "processors" to "threads" in the GUI
- add a warning box about unexpected results when increasing #threads
- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will
