Metalball drawing: rename mball helpers to handles

and also rename some related functions

Cleanup: quiet warning

UI: Hide grease pencil paper if not gpencil object

GWN: Fix ubo debug printf

GWN: Fix attrib arrays giving incorrect name depending on the platform.

It seems that some opengl implementations are returning "[0]" after array names but some others dont.

Remove the "[0]" so everything is consistent.

Fix pixelate for negative values

If the object was in negative location, the draw got full opaque.

Merge branch 'master' into blender2.8

Code cleanup: simplify switch statement, ensure we catch missing enums.

Fix T54073: crash and uninitialized memory in Cycles displacement hashing.

Fix crash reading deg_point_cache_transform.blend test, saved with 2.8.

In general 2.8 files may not be readable in master, but might as well fix
this case so all the lib/tests can be opened still.

Cleanup: Remove debug-only code

Fix error for render onion skin

The flag was not working as expected in renders

Fix T54076: MCE in Graph mode - clip.graph_select_border does not work by header menu

While the script should be using INVOKE_PREVIEW for operators in clip view,
window manager was lacking some switch statements.

Thanks Brecht fore review!

Rename function macro after merge

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' into blender2.8

Cleanup: rename BLI_thread.h API

- Use BLI_threadpool_ prefix for (deprecated)
thread/listbase API.
- Use BLI_thread as prefix for other functions.

See P614 to apply instead of manually resolving conflicts.

Merge branch 'master' into blender2.8

Cleanup: use '_len' instead of '_size' w/ BLI API

- When returning the number of items in a collection use BLI_*_len()
- Keep _size() for size in bytes.
- Keep _count() for data structures that don't store length
(hint this isn't a simple getter).

See P611 to apply instead of manually resolving conflicts.

Cleanup: Style, braces with macros
