Added function called WM_set_locked_interface which does
two things:
- Prevents event queue from being handled, so no operators
(see below) or values are even possible to run or change.
This prevents any kind of "destructive" action performed
from user while rendering.
- Locks interface refresh for regions which does have lock
set to truth in their template. Currently it's just a 3D
viewport, but in the future more regions could be considered
unsafe, or we could want to lock different parts of
interface when doing different jobs.
This is needed because 3D viewport could be using or changing
the same data as renderer currently uses, leading to threading
conflict.
Notifiers are still allowed to handle, so render progress is
seen on the screen, but would need to doublecheck on this, in
terms some notifiers could be changing the data.
For now interface locking happens for render job only in case
"Lock Interface" checkbox is enabled.
Other tools like backing would also benefit of this option.
It is possible to mark operator as safe to be used in locked
interface mode by adding OPTYPE_ALLOW_LOCKED bit to operator
template flags.
This bit is completely handled by wm_evem_system, not
with operator run routines, so it's still possible to
run operators from drivers and handlers.
Currently allowed image editor navigation and zooming.

Allow loading of image sequences in addition to single images in the open image operator
I solved it by adding the possibility to load an image sequence in the Load Image Operator.
The image user is passed in the operator customdata now as well, best solution for now, but general handling of image user still a bit weak. The offset and length of the image sequence is now calculated in the image open operator by storing all found frames in a list and sorting this list.

Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

This was actually a regression after color management re-implementation, need
to copy settings from saved image buffer to an original one since they might
be modified during save.
Also noticed image format planes detection didn't work properly from an image
buffer. Made it so save operator works fine now, but also marked a TODO in
BKE_imbuf_to_image_format() which needs to be investigated further.
Summary:
Behaves very much the same as cache for Movie Clip datablock:
- Image now have `MovieCache *cache` field which replaced
legacy `ListBase ibufs`.
This allows image datablock to easily keep of image
buffers which are owned by itself. This field isn't
saved to the file and getting restored on undo steps.
However, cache limit is global for movies, sequences
and image datablocks now. So overall cached image buffers
size will not go above cache limit size in user
preferences.
- Image buffers which are marked as BITMAPDIRTY will never
be freed from the cache.
- Added utility function to iterate over image buffers
saved in movie cache.
- Movie cache cleanup check callback now have ImBuf argument
which can be used in a condition of cleanup.
- Added some utility functions which replaces legacy ibufs
iterations with image cache iteration which happens from
inside a lock.
- Fixed `image_mem_size()` which was only counting one of
the buffers if both float and byte buffer present.
Additional notes:
- `BKE_image_get_first_ibuf()` is rather stupid, but direct
access to ibufs->first was also the same stupid idea.
Would consider avoid this function is another project.
- There are some places which doesn't look threadsafe, but
they already were not so much threadsafe anyway before.
So think not a big deal with solving this later.
Finally solves infinite memory usage by image sequences! :)

Fixes this problem:
*Go to the Blender (BI) textures tab and open an existing image.
*Hit on the plus sign next to datablock to create a new image.
*Complete the creation process and switch back to the first (loaded) image.
-> The image user count raises... will raise as often as you hit the plus sign
The SAMPLELINE flag in histogram was set during the BKE_histogram_update_sample_line function. That function in turn is called during every scope update in area draw function, meaning that during render
it constantly gets set. OTOH the operator tries to disable the flag on invoke, which "cancels" the sample line by default. So during render the operator un-setting of the flag has no effect, because the
render job immediatly triggers a redraw, which updates scopes and sets it again.
Moved the flag out of the actual sample line update function into the operator execute. Now only the operator enables/disables overall sample line drawing, while the rest of the update works as before.
This mimics the behaviour we have in the Clip Editor.
I personally would prefer if we had no border once in fullscreen
(current border is 5 pixels).
I will consult Sergey Sharybin first to see if we can change that in the clip editor as well (though there I
believe the border is useful - the bottom of the editor is used to indicate 'tracked' frames.
Issue was caused by operator redo saving values for previous
inverted channels, meaning the same channels will be inverted
next time operator runs.
Don't think it's useful to save operator values here, since
you don;t have visual feedback about which channels were
inverted. So marked all this properties as SKIP_SAVE. Gives
much more predictable results.
in fact the problem was caused by own previous fix/improvement for a different case, now this works as follows...
- render uses last-saved name, falls back to 'untitled' in blend file path.
- non render uses id-name always, saves into dir of last-saved image, fall back to blend file path.
Was caused by svn rev53181, and it worked before because
image buffer didn't have quality set and in this case
fall back to scene settings happened.
Now or render result quality from scene settings is always
used, image buffer's settings is ignored.
This makes it so sample line (for all image editor, sequencer and compositor)
displaying managed color for byte buffers as well. It was simply not implemented
before.

Get rid of BLI_splitdirstring, replace with calls to BLI_split_dirfile, BLI_split_dir_part and BLI_split_file_part as appropriate.
