Newer OpenSubdiv brings fixes and improvements for non-manifold meshes,
which fixes some crashes we've experienced in the recent past when using
Gregory patches.
Additionally, thing new version of OpenSubdiv brings sparse patches,
which allows to multi-thread topology refinement step.
This time both full `make deps` and final compilation is tested on
a freshly installed CentOS 7.
The thing is: OpenImageIO is not configured to use an external PugiXML
library, so it was compiling its own.
At the same time the OpenShadingLanguage library was commanded to use
an externally compiled PugiXML. This caused some sort of discrepancy
which lead to Blender-link-time errors. Could be linking error, could
be namespace related, could be ABI related. In any case since we do
have PugiXML in the OpenImageIO already lets just stick to it.
The change did break compilation on default Ubuntu install for Stefan
and on default CentOS install for myself.
This reverts commit 64671e53d20c2a30c64b98c747b0e002218c3952.
This is in preparation of an the upcoming fix where we need to use a Metal
layer to avoid performance issue when drawing with OpenGL. Note that we already
only officially support 10.12+, the difference with this change is that Blender
will not start at all on 10.9 and 10.10.
Most of the source tarballs are retrieved via http, but a few remain
that are still downloaded via ftp. This causes some pain with corporate
firewalls, so moving the last two URIs to http helps ease the build process.

llvm generates some header files at build time that differ between
debug/release causing linker errors when you used the release headers
for a debug build.
This bring macOS on par with Windows and Linux. It uses the OpenMP library
added to our precompiled libraries.
Custom flags are set because FindOpenMP from CMake below 3.12 does not support
AppleClang, and more recent versions do not work with our custom directory
location either.

Note that this is turned off by default and must be enabled at build time with the CMake WITH_CYCLES_EMBREE flag.
Embree must be built as a static library with ray masking turned on, the `make deps` scripts have been updated accordingly.
There, Embree is off by default too and must be enabled with the WITH_EMBREE flag.
Using Embree allows for much faster rendering of deformation motion blur while reducing the memory footprint.
TODO: GPU implementation, deduplication of data, leveraging more of Embrees features (e.g. tessellation cache).

ffi stubbornly wants to put libs in lib64 even when you tell it not to on some linux distributions.
patch based on sed fix the gentoo guys did [1]

Mainly this is following Linux to build own xml2/lzma/ssl/sqlite and linking
them all statically. This ensures the Python ssl module uses a recent openssl
version rather than a very old one shipped with macOS.
There is system-wide libz development package installed by default,
needed for some other dependencies. This patch ensures Python will
use our own self-compiled Zlib.
This involved getting SSL compiled from sources first, ensuring
it is a static library placement independent code. Configuration
is based on what Debian is using. CFlags required to have own
configuration file, which i didn't find a better place that next
to the corresponding CMake file.
It is OpenSSL btw.
It is set to Python via --with-openssl= configuration argument.
This works fine in a clean chroot, but having libssl-dev installed
might make Python to prefer system wide library, This was worked
around by using libssl_pic.a name for the library and modifying
setup.py. Would be cool to ensure system wide libraries are not
a problem, but official release builder is safe against this,
since it will catch possible non-static dependencies.
There is also a new map file which shadows bunch of Python
symbols. Without this Python's shared libraries might bring
conflicting symbols to Blender namespace at runtime.
Hopefully this doesn't break other platforms.
there is an issue with objects destructing in a non deterministic way during process shutdown, temporary work around this until osl has a fix in place.
