Fix out of bound array access

And other minor fixes.

Fix compilation error with latest OIIO 1.7.8

There are some changes in OIIO includes so now need to do some
things differently.

Fix T50094: Crash when viewport rendering point density texture

The idea is simple: cache PD resolution from cache_point_density() RNA
function because that one is supposed to be called while database is
locked for original synchronization.

Ideally we would also pass array size to the sampling function, but
it turned out to be quite problematic because API only accepts int type
and passing size_t might cause some weird behavior.

Cycles: Pass extra array size argument to builtin image pixels functions

This is a way to avoid possible memory corruption when render threads works
in parallel with UI thread.

Not guarantees complete safe, but makes things easier to check anyway.

Math lib: Fix use function of wrong dimension

Seems to be a typo in recent commit e1e49fd.

Fix T50029: BVHTree.FromPolygons memory leak

Fix C++11 building on MSVC 2015

Newest 2017 not yet supported because i don't know its version symbol...

Default to C++11 for all compilers (2.8)

This fixes multiple problems on latest Mac OS + Xcode. Hopefully does not cause any on other platforms.

The Xcode detection logic could use further cleanup. It's checking several old versions that are unsupported for Blender 2.8+ development.

DerivedMeshes clean up their draw-batch caches

No more "Not freed memory blocks"!

This code was almost ready 1 month ago, waiting for other pieces to fall into place.

Gawain: batch mode uses buffer ID funcs

The _discard functions now free their resources! These were waiting on thread-safe ID management, which we now have.

Gawain: immediate mode uses buffer ID funcs

These functions are called very infrequently.

Gawain: manage GL buffer IDs in a thread-safe way

Needed because deps graph can destroy objects from any thread. We ran into the same problem & solved it in GPU_buffers.

Implemented in C++11 since it provides the needed machinery. The interface is in C like the rest of Gawain.

[msvc] remove /opt all together and revert to the default behavior /opt:ref for release builds, /opt:noref for debug builds.

Comment: explain viewport & render pixel-size

It wasn't all that clear why both pixel-sizes are needed.
