The GIMP version string and the backtrace both look completely wrong
when pasted as-is on gitlab. Somehow all linefeed are gone.
This can be fixed by surrounding these as blocks (triple backticks),
using markdown syntax. Of course now the debug content is not for our
tracker only since packagers are encouraged to replace with their own
tracker URL, but this small markdown syntax is simple enough that it
should not break formatting on other platforms (as far as I know).

In gimp_parallel_run_async(), when aborting a GimpAsync operation
in reponse to its "cancel" signal, properly clean up internal data
attached to the object, to avoid use-after-free if the signal is
emitted again.
(cherry picked from commit 3fa4c01bcf)
Add a boolean "independent" parameter to gimp_parallel_run_async().
When FALSE, the passed function is run in the shared async thread
pool; when TRUE, the passed function is run in an independent
thread.
Generally, async operations should run in the async pool, however,
it might be desirable to run long-standing operations, especially
ones that can't be canceled, in independent threads. This avoids
stalling quicker operations, and shutdown.
Adapt the rest of the code for the change. In particular,
initialize the font cache in an independent thread.

In gimp_parallel_run_async(), connect to the returned GimpAsync's
"cancel" signal, and abort the operation in response if it's still
enqueued, i.e., if its execution hasn't started yet.
(cherry picked from commit 3958ffbe50)
Have GimpAsync implement the GimpWaitable and GimpCancelable
interfaces, added in the previous two commits, instead of providing
its own public version of the corresponding functions.
Add gimp_async_cancel_and_wait() as a convenience function for both
canceling an async operation, and waiting for it to complete.
Adapt the rest of the code to the change.

The code was basically leaking memory everywhere, and apparently on
purpose (according to a top comment). Even on short-lived process, not
properly managing memory is not a good habit, especially if we plan to
maintain a program for the long run.
So here are some fixes. I'm sure I must have missed some places (code
was a mess), and hopefully I broke nothing. But that's good for now. At
least it is somewhat sane code now.

Since commit 58fa382001, gimptool would accept source files with
non-standard extensions when using known C or C++ compilers. This would
include source with no extensions at all.
When this happens, do not try to set a pointer to a non-existing dot
separator to '\0'. That obviously segfaults.

Unlike the last two commits, we don't port GimpConfig to
G_DEFINE_INTERFACE(), since we need to provide a base initializer
for it. However, this commit aligns it with the rest of our
intefaces, by renaming gimp_config_interface_get_type() to
gimp_config_get_type(), and by performing class initialization for
the interface in a separate function than base initialization.
Keep gimp_config_interface_get_type() around as a deprecated
function, to maintain ABI compatibility. It will be removed in a
separate commit in master, so that this commit can be easily
cherry-picked to gimp-2-10.
(cherry picked from commit 5f8643a6ee)
... instead of calling g_type_register_static() ourselves.
Keep the old foo_interface_get_type() (replaced with
foo_get_type()) around as deprecated functions, to maintain ABI
compatibility. They will be removed in a separate commit in
master, so that this commit can be easily cherry-picked to
gimp-2-10.

Fonts should not be blocking startup as this provides a very bad
experience when people have a lot of fonts. This was experienced even
more on Windows where loading time are often excessively long.
We were already running font loading in a thread, yet were still
blocking startup (thread was only so that the loading status GUI could
get updated as a feedback). Now we will only start loading and proceed
directly to next steps.
While fonts are not loaded, the text tool will not be usable, yet all
other activities can be performed.
(cherry picked from commit 2484dec7d5)
Improve the formalism of a GimpAsync object being "sycned"
(previously referred to as the main thread being "synced" with the
async thread), by both providing a gimp_async_is_synced() function,
separate from gimp_async_is_stopped(), and by improving the type
and function descriptions.
Make sure all previously added callbacks have been called after a
call to gimp_async_wait[_until](), even if these functions are
called from within a callback.
(cherry picked from commit a901c3c1f4)
Replace the custom threading code with a call to
gimp_parallel_run_async(). This simplifies the code, while
maintaining the current (blocking) behavior. In the future, we
might build upon this to actually load the fonts in the background.
(cherry picked from commit 3e92e7a449)
... which is similar to gimp_async_wait(), taking an 'end_time'
parameter, controlling how long to wait for the async operation to
complete.
(cherry picked from commit 68c57548fd)
The default stack size for new threads on MacOS is 512 KiB, making
our 512 KiB limit for stack-allocated buffers in
gimp_operation_layer_mode_real_process() too high. Lower it to
256 KiB.
(cherry picked from commit 367399e5c0)
In gimp_drawable_gradient(), pass the undo description ("Gradient")
to gimp_gegl_apply_operation(), so that its displayed as the
progress text while rendering the gradient, even when applying a
shaped gradient, in which case we end the progress after
calculating the distance map, causing the progress text be NULL
during rendering unless explicitly set.
(cherry picked from commit deee2f14f5)
... which is a drop-in replacement for gegl_buffer_copy(),
parallelizing the copy operation when the source and destination
formats are different, requiring a conversion.

and remove all clipping hacks for drawing the canvas background, turns
out they never worked and we were relying on the pattern set on the
window, gah! This optimizes away one entire step of drawing of image
size, for each expose...
