Fix crash when Making Duplicates Real for groups

Layers: Fix selected lamp and dupli count for info stats

Make auto handle placement aware of cyclic extrapolation.

Cyclic extrapolation is implemented as an f-curve modifier, so this
technically violates abstraction separation and is something of a hack.
However without such behavior achieving smooth looping with cyclic
extrapolation is extremely cumbersome.

The new behavior is applied when the first modifier is Cyclic
extrapolation in Repeat or Repeat with Offset mode without
using influence, repeat count or range restrictions.

This change in behavior means that curve handles have to be updated
when the modifier is added, removed or its options change. Due to the
way code is structured, it seems it requires a helper link to the
containing curve from the modifier object.

Fix T52959: Local view looses clip range on exit

Fix T53074: Use the pybuffer->itemsize to get the corresponding GLtype

It seems that `typestr` does not always define the final size of the element. And it varies by operating system.

Then use the `typestr` only to know the itemtype is `float` type or not.

Fix T53007: OpenSubdiv + transparency = artefact/crashes

GPU: Report number of compressed texture formats to help nailing crahs down in the future

GPU: Fix memory corruption in GPU_debug on GTX1080

Number of texture formats is 51, which is greater than allowed size of 32.

Added alpha channel check to Alembic unit test

It was broken due to 823bcf1689a3dbd44dd77b2c8ea46b9b54073c46, which added
alpha information and thus changed tuple size from 3 to 4 items.

Merge branch 'master' into blender2.8

WM: move gesture operator callbacks into own file

`wm_operators.c` is near 5k LOC with lots of mixed functionality,
extract gesture callbacks since they aren't closely related.

Merge branch 'master' into blender2.8

Cleanup: use 'e' prefix for enum typedefs

Convention was only followed loosely,
apply to DNA where changes aren't likely to conflict.

(Skipped ModifierType for eg).

Merge branch 'master' into blender2.8

WM: immediate line-gesture activation on tweak

Matches border-gesture behavior,
needed for binding bisect to tweak event.

GPUFramebuffer: Fix recursive downsample exiting early.

I should really proof read my commits a bit more.

Knife Tool: add wait_for_event option

GPU Extension: Fix AMD Vega + open source driver detection.

Docs: Add comments on workspace removal functions
