* Image cache rewrite to using generic movie cache
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! :)

* Implement GPU-side dither

Summary:
Uses some magic pseudo-random which is actually a
texture coordinate hashing function.

TODOs:
- Dither noise is the same for all the frames.
- It's different from Floyd's dither we've been
　using before.
- Currently CPU and GPU dithering used different
　implementation. Ideally we need to use the same
　dither in CPU.

* Minor optimization for strlen and memcpy calls for reading blend files
　Summary:
　This commit removes ~10000 strlen calls and ~100000 memcpy calls in blender (profiled with blender --background), ~10000 memcpy calls in makesdna.
　There is no need to create null-terminated strings for atoi, because it converts only the initial portion of the string anyway.
　Also it was noticed that DNA_elem_array_size and arraysize functions work only with full strings, so there is no point to calculate strlen.

* Support units in modal numinput
　Summary:
　　This completly changes the way modal numinput is handled. Now, edited expression is a string, which then gets unit- and py-evaluated to
　　get a float value.
　　We gain many power and flexibility, but lose a few "shortcuts" like '-' to negate, or '/' to inverse (if they are really needed,
　　we still can add them with modifiers, like e.g. ctrl-/ or so).
　Features:
　　- units (cm, ", deg, etc.).
　　- basic operations from python/BKE_unit (+, *, **, etc.), and math constants and functions (pi, sin, etc.).
　　- you can navigate in edited value (left/right key, ctrl to move by block) and insert/delete chars, e.g. to fix a typo without
　　　having to rewrite everything.
　　- you can go to next/previous value with (ctrl-)TAB key.
　　- As before, hitting backspace after having deleted all leading chars will first reset the edited value to init state,
　　　and on second press, the whole "modal numinput" editing will be cancelled, going back to usual transform with mouse.
　Notes:
　　- Did not touch to how values are shown in header when modal numinput is not enabled (would do that in another commit),
　　　so this is still quite inconsistent.
　　- Added back radian support in BKE_unit.
　　- Added arcminute/arcsecond to BKE_unit.
　　(those unit changes affect all angle UI controls, btw, so you can now enter radians or longitude/latitude values when in degrees units).

* Fix T37709: Memory corruption when freeing custom bone shape objects
　Summary:
　　Issue was caused by access to pchan->custom object from channel free
　　function when freeing all objects from main. Order of objects free
　　is not defined and such an access might easily end up with access
　　to freed memory.
　　We don't need to do user counter stuff when freeing main, so added
　　an _ex functions with do_id_user flag which is used when freeing main.
　　We had the same issue with other datablocks, so now it should be
　　easier to support relevant user counter.
　　This issue was caused by the fix for T36391, so perhaps that's indeed
　　high time to do real user counter.

　要約すると、これは開放されたデータブロックへのアクセスによるものということらしい。

* Rigidbody: Add option to choose mesh source for collision shapes
　The options are:
　　Base: Base mesh
　　Deform: shape keys and deform modifiers
　　Final: All deformations and modifiers

　It would be nice to have a way of specifying where exactly in the
　modifier stack the collision shape is generated. However this is not
　staight forward since the rigid body simulation is not part of the
　modifier system and would require hacks to make it work.

* Fix crash when having multiple text objects sharing the same curve datablock
　Issue was caused by BKE_vfont_to_curve() modifying curve->nurbs list which gave threading issues.
　Now added BKE_vfont_to_curve_nubase() which operates on a given nurbs list base which is local
　in do_makeDispListCurveTypes().
　By the looks of it it wouldn't give speed regression because previously it also was creating
　nurbs for every font object sharing the same curve data.

* Fix T38024 crash when rebuilding sculpt mode buffers.
　Main issue here is that glBuf* calls were invoked from threads different than

　Fix here is twofold:
　* add an ID buffer in buffer pool that handles pbvh buffers and is freed
　from main thread when gpu_buffer_pool_free_unused is called.
　* do not create glbuffers in derivedmesh creation routine, rather tag nodes
　for update and create those in the draw function
　(guaranteed to be called from main thread)

* Fix crash happening in Cycles fcurve modifier
　Summary:
　Crash was happening because of fcurve modifier stack
　used modifier's DNA to store temporary data.
　Now made it so storage for such a thing is being
　allocated locally per object update so multiple objects
　which shares the same animation wouldn't run into
　threading conflict anymore.
　This storage might be a part of EvaluationContext,
　but that'd mean passing this context all over in
　object_where_is which will clutter API for now without
　actual benefit for this.
　Optimization notes: storage is only being allocated
　if there're Cycles modifier in the stack, so there're
　no extra allocations happening in all other cases.
　To make code a bit less cluttered with this storage
　passing all over the place added extra callbacks to
　the FModifier storage which runs evaluation with the
　given storage.
