Cycles: Simplify some extra OpenCL query code

Update CLEW to latest version

Needed to get access to some AMD extensions.

Cycles: Cleanup, add some utility functions to shorten access to low level API

Should be no functional changes.

OpenGL: convert to new matrix API (part 3)

Part of T49450

OpenGL: remove 'circ' helper function

This was no longer being used.
Part of T49043

fix use-before-init error + local cleanup

"path" was being used uninitialized. Thanks for the warning, clang!

remove gpuMatrixUpdate_legacy function

No longer needed since 231b5d96bbfd77253941dd37cc4929e4e119d706 tracks dirty state of legacy matrix stacks.

Part of T49450

OpenGL: convert to new matrix API (part 2 of x)

Part of T49450

For this batch I focused on usage of gpuMatrixUpdate_legacy.

track dirty state of legacy matrix API

This is used to send latest matrix values to shader when drawing.

Previously handled by calling OpenGL matrix functions, followed by gpuMatrixUpdate_legacy. With this change that function is no longer needed.

Part of T49450

OpenGL: remove older matrix macros

Some of these were unused, the others are now handled by GPU_matrix.

Part of T49450

OpenGL: convert to new matrix API (part 1 of x)

Part of T49450

For this batch I focused on usage of (now-obsolete) macros in BIF_gl.h

add missing gpuRotate2D function

Prototype was there, we just weren't using this yet.

Part of T49450

OpenGL: more legacy support for matrix routines

For the sake of forward progress on T49450

We can now replace legacy gl* matrix function calls with their gpu equivalents. "Inactive" in this code means we're using the legacy matrix stacks, not our own. Setting up the proper gpuMatrixBegin2D/3D/End calls can be done afterward.

Most or all of this will be removed after the transition to core profile.

Cycles: Fix wrong vector allocation in the mesh sync code

Cycles: Fix building of OpenCL kernels

Theres no overloading of functions in OpenCL so we can't make use of
`safe_normalize` with `float2`.

Fix T51012: Surface modifier was not working with curves

This prevented the Force Field Curve Shape of working

Fix T50268: Cycles allows to select un supported GPUs for OpenCL

Cycles: Update remaining time once per second without waiting for a tile change

Previously, the code would only update the status string if the main status changed.
However, the main status did not include the remaining time, and therefore it wasn't updated until the amount of rendered tiles (which is part of the main status) changed.

This commit therefore makes the BlenderSession remember the time of the last status update and forces a status update if the last one was more than a second ago.

Reviewers: sergey

Differential Revision: https://developer.blender.org/D2465

Edit Mode Engine: Remove unecessary matrix.

Object Mode Engine: New outline method.

We render selected meshes into another buffer and use a screen space shader to expand the color out of the mesh silouhette.

Pros: only one additionnal render pass is needed (like old outline code), and we have occluded informations.
Cons: memory usage is a problem. This method needs 2 color buffer to ping pong when expanding the outline and 1 depth buffer to test occluded fragments. This gives a 88 bits/pix memory footprint.

Idea: Since we don't need all color range but only some uniform colors (theme colors) we could manipulate only the color ID instead of the whole color this could cut the color buffer size and lower the memory footprint to 58 bits/pix.
