08c1f5bf33 Cycles: Improve sampling of area lights
This patch uses the sampling method described in "A Low Distortion Map Between Triangle and Square" by Eric Heitz.
The benefit is avoiding sqrt in the calculation, which could be cheaper on some architectures, and the result is
more even sampling across the triangle surface.

Based on ideas from

ccf43fe605 Cycles: Fix rendering instanced smoke domain.
The problem was that Cycles would store a pointer to an object in
`DEGObjectIterData->templ_dupli_object`. This pointer was then accessed
when the iterator was already freed.

183ba284f2 Cleanup: make guarded memory allocation always thread safe
Previously this would be enabled when threads were used, but threads are now
basically always in use so there is no point. Further, this is only needed for
guarded allocation with --debug-memory which is not performance critical.

2ad5131f77 OpenSubdiv: Cleanyp, remove old GPU code

library.

22f68f85a4 OpenSubdiv: Cleanup, remove unused topology orientation code
The code was trying to make winding consistent and manifold, same as
OpenSubdiv expects it to.

Unfortunately, the code was having some issues in corner cases so the
winding wasn't really correct.
Fortunately, the latter (compared to when this code was originally
written) supports orientation on OpenSubdiv side.

Removing code which is currently unused in Blender and which had
known issues. Is simple enough to bring the code from Git history
if the functionality is needed in the future.

27cac4a102 Fix T62422: Baking ray distance do not work
The previous naming scheme for the "selected to active" baking options
lead to confusion and they were not describing what they actually did.

To remedy this, I've added a new settings that does what the older setting implied it did.

005d04e145 Manta: Cleanup, strict compiler flag
For some reason was only visible with gcc-10 in release builds.

Kind of makes sense since there is no CMake code which removes strict
compiler flag, so deal with strict flags in the code itself.

d9773edaa3 Cycles: code refactor to bake using regular render session and tiles
There should be no user visible change from this, except that tile size
now affects performance. The goal here is to simplify bake denoising in
D3099, letting it reuse more denoising tiles and pass code.

A lot of code is now shared with regular rendering, with the two main
differences being that we read some render result passes from the bake API
when starting to render a tile, and call the bake kernel instead of the
path trace kernel.

With this kind of design where Cycles asks for tiles from the bake API,
it should eventually be easier to reduce memory usage, show tiles as
they are baked, or bake multiple passes at once, though there's still
quite some work needed for that.

2b36cf3118 Libmv: Fix crash solving when having negative frames
Don't use linear array with frame as an index since it has the
following disadvantages:

- Requires every application to take care of frame remapping, which
  could be way more annoying than it sounds.

- Inefficient from memory point of view when solving part of a footage
  which is closer to the end of frame range.

Using map technically is slower from performance point of view, but
could not feel any difference as the actual computation is way more
complex than access of camera on individual frames.

c880e54a95 Cycles: Refactor microfacet BSDFs to remove separate anisotropy code
Since the sampling and evaluation functions handle both cases anyways,
there's not really a point for keeping the distinction in the kernel,
so we might as well cut down the number of CLOSURE_BSDF_MICROFACETs a bit.
