This change mainly caused by too dark icon generated for texture brushes,
but also makes it a bit more straightforward from what's going on point of view.

Color management would be applied on both of float and byte buffers on image
save in cases if file format doesn't require linear float buffer and if image
is saving as render result.
This solves both initial report issue and TODO marked in previous fix.
Also de-duplicated image buffer color managing code and gave some more
meaningful names for few functions. Also wrote documentation around this
function, so current assumptions about spaces should be clear enough.
Made regression tests by saving EXR/PNG images to all supported format and
rendering OpenGL/Normal animation, in all cases seems everything is fine,
but more tests for sure would be welcome.

Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
images/movies from color space in which file is saved to Blender's linear
space (for float images, byte images are not internally converted, only input
space is stored for such images and used later).
This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
These are different ways to view the image on the same display device.
For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
display gamma.
- RGB curves are user-defined curves which are applying before display
transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
to support other spaces, but it's quite large project which isn't so
much important.
- Legacy Color Management option disabled is emulated by using None display.
It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
in the same way as previous release with color management enabled.

Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO
integration and to Brecht van Lommel for some further development and code/
usecase review!

World is being localized without increasing ID users, so no need
to decrease ID users on localized world free.

Shader preview job localizes material without referencing it as a user,
so don't need to unreference itself as a user from this material.
Added BKE_material_free_ex function which could skip user dereferencing.
This also removed old hack with mtex users.

Seems the issue was caused by render layer node overwritng active scene
when render button is clicked. It lead t situations when job was adding
with owner of rendering scene, but modal callback was checking for render
jobs existing for current active scene. There was no such jobs so operator
used to finish at this point and free report list used by render pipeline.
Solved by storing operator owner in operator's custom data. Probably
there's nicer way to do fix this issue but currently can't think of it.

Issue was caused by the fact, that sequencer is working in sRGB space, but
when there's only image input strips we need to make sure conversion from
byte to float buffer would keep float buffer in sRGB space and wouldn't
make it linear as it's supposed to be in other areas.

- Make sure functions are named in way BKE_<object>_<action> (same way as RNA callbacks)
- Make functions which are used by mball.c only static and remove their prototypes
from public header file.
Further cleanup is coming.
