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]
[1] https://bugs.gentoo.org/462814
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.
Tested with Debian Testing, might need some adjustements for other
distributions...
Also removed last patches we used here, we shall not need any anymore!
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.
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.
-Moved from dynamic link to static on windows
-gained lcms/tinyxml/yamlcpp deps, since we need a little more control over the build flags than the build-in options will provide.
-expanded build_deps.cmd with 2017 support, it can't locate msvc2017 so needs to be run from developer prompt.
-Newer cmake was unhappy with openal's cmakelists.txt
-collada has warning as error on and errored out on new msvc2017 warnings.
This commit contains the minimum to make clang build/work with blender, asan and ninja build support is forthcoming
Things to note:
1) Builds and runs, and is able to pass all tests (except for the freestyle_stroke_material.blend test which was broken at that time for all platforms by the looks of it)
2) It's slightly faster than msvc when using cycles. (time in seconds, on an i7-3370)

3) clang on windows uses a drop in replacement for the Microsoft cl.exe (takes some of the Microsoft parameters, but not all, and takes some of the clang parameters but not all) and uses ms headers + libraries + linker, so you still need visual studio installed and will use our existing vc14 svn libs.
4) X64 only currently, X86 builds but crashes on startup.
5) Tested with llvm/clang 6.0.0
6) Requires visual studio integration, available at https://github.com/LazyDodo/llvm-vs2017-integration
7) The Microsoft compiler spawns a few copies of cl in parallel to get faster build times, clang doesn't, so the build time is 3-4x slower than with msvc.
8) No openmp support yet. Have not looked at this much, the binary distribution of clang doesn't seem to include it on windows.
9) No ASAN support yet, some of the sanitizers can be made to work, but it was decided to leave support out of this commit.

-No more hardcoded python35/36 tokens in the scripts
-disabled python module for boost, was not used
-Updated patches for python to support building with msvc2013
Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.
Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.
