DRW: Fix lightprobe objects outlines.

GPU: Add GPU_SHADER_INSTANCE_VARIYING_ID_VARIYING_SIZE.

Will be used for probe outline id drawing.

DRW: Add DRW_UNIFORM_INT_COPY.

This allow to use int uniforms that are not references. Convenient for ids.

Cleanup collada: improved class description comment

Refactor Collada: Moved static class functions to collada_utils

Reason: The functions had nothing to do with the class

Cleanup: Various code/style tweaks to GP code

Depsgraph: Fix unwanted node tree copy-over

Was caused by two things from the past:

- Tagging would set id->recalc to COW update flag.
This one is to be ignored.

- Particle tagging will use psys recalc flags on id->recalc,
but we only need to use flags from particles. Otherwise
it will be some collisions in bit masks.

Merge branch 'master' into collada

bpy consistency fix handler_add(handle)

This doesn't change the API, so it doesn't affect any script.
However it give more consistent error messages.

bpy blf api example update

With changes from Campbell Barton as well.

Compiler warning fixes on GCC

* gpencil_add_*_shgroup() - Removed unused parameters (gpd)

* Fix warning about rgba being uninitialised in gpencil_fill.c::get_pixel()
- The non-float case here looks like it shouldn't ever happen, but for good measure,
I've added an assert + set a value here to keep compiler happy.

* Fix uninitialised var in gp_brush_drawcursor() - paintbrush

* GPencilOffsetModifier defined an RNA vertex group name set function, but didn't use it

Merge branch 'master' into blender2.8

Fix (unreported) RNA sometimes trying to get named sub-props from non-Group IDProp.

Why exactly this happens remains unclear, found that in the
autumn.blenrig file of Spring production while working on static
overrides... Tons of ugly IDProps in that rig. xD

Pose: fix wpaint + pose mode pick & linked select

Merge remote-tracking branch 'origin/master' into collada-new

Fix blenderplayer and collada build.

Cleanup Collada: moved typedefs to more intuitive locations

cleanup: indentation and class method declarations

Refactor Collada: Major rewrite of the AnimationExporter

* Mostly reorganized the classes and made them more readable.
* The animation sampler now can be used for any animation curve.
Before the sampler only looked at curves which are supported by
Standard Collada 1.4. However the Collada exporter currently
ignores all animation curves which are not covered by the 1.4.1
Collada Standards. There is still some room for improvements
here (work in progres)
* Removed some unnecessary dependencies and cleaned up many
functions which have become unnecessary and no longer used.
* moved functions between classes to better match the class
responsibilities.
* took care that the functions are kept small and understandable
* removed intermediate structures which are no longer needed
* cleanly separated the Animation sample part from the
Collada part so that they can be treated independently from each
other

Known issues:

* Some exports do currently not work reliably, among those
are the camera animations, material animations and light animations
those animations will be added back next (work in progres)

* Exporting animation curves with keyframes (and tangents)
sometimes results in odd curves (when parent inverse matrix is involved)
This needs to be checked in more depth.

* Export of "all animations in scene" is disabled because the
Collada Importer can not handle this reliably at the
moment (work in progres).

Fix Collada: replaced nullptr by NULL at various places

To remain compatible with the c++ version used in master
