Immediate Mode / DerivedMesh: Handle UV Shadow

Depsgraph: placeholder function for COW objects query

CTX_data_depsgraph(bContext *C);

Immediate Mode: glPop/glPushClientAttrib

Bumped Alembic library version to 1.7.1

This provides us with a clearer API (so I don't have to use const_cast<>
in upcoming code). It also allows layering of different Alembic files,
so you can have a base file and load a separate file containing overrides.

Verbally approved by Dr. Sergey.

Buildbot: Update master config

Alembic: force ALEMBIC_LIB_USES_BOOST=ON when not using C++11

Alembic requires one of ALEMBIC_LIB_USES_BOOST, ALEMBIC_LIB_USES_TR1, or
C++11, and silently defaults to the latter if the former two are OFF.

Before this change, Alembic was only built without C++11 of OpenEXR
was built at the same time. This dependency was both unnecessary and
undocumented.

Task: Remove non-atomic pool suspended flag assignment

This was done some lines above by atomic fetch and and.

Buildbot: Update master config

Fix bad level call.

Cleanup: avoid long lines (search tools complain!)

fix node editor drawing (T51086)

Fixed a few issues
- wrong transform matrices
- assert on node with no sockets
- color of collapsed nodes, some title areas

Also includes minor cleanup.

Draw Manager: Fix engine_type not set

Infinite Grid: View angle fade

and show Z axis in special persp views

Draw Manager: Use engine type pointer instead of engine name.

Faster search

Object Engine: Fix multi user lamp data display bug.

Objects that were using the same lamp data were having the same display matrices.
This is fixed by allowing engine to store a memory block inside the object itself.

Draw Manager: Fix Cache timers

Also expand the timer average range.

GPULamp: Separate GPULamp from GPUMaterial

Since we need GPULamps for draw engines, it makes sense to separate them.

Draw Manager: Fix glBlitFramebuffer error

Eevee: LTC area lights

Using Linear Transform Cosines to compute area lighting. This is far more accurate than other techniques but also slower.

We use rotating quad to mimic sphere area light. For a better approximation, we use a rotating octogon.
