OSL 1.10.9 fixes osl-bug 866 [1] which is long standing issue
on windows where paths get un-escaped and osl breaks when you
install it to for instance c:\blender-tests\new-boolean
This patch bumps osl to 1.10.9, and since osl is llvm's
only consumer, llvm/clang were bumped 9.0.1
Removed some of the patches that were no longer needed
Builds and passes all tests on windows and linux

This aligns with the VFX reference platform 2020 along with the decision
to stick to Python 3.7, see T68774.
Blosc was downgraded to 1.5 as recommended by the OpenVDB documentation.
IlmBase and OpenEXR are now built together with CMake rather separately
using autoconf.

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.
Now, things are becoming REALLY confusing. The script does build
pugi, but is never telling OIIO to use an external one. Which makes
it to use a bundled one.
Trying to link OSL to a different version of pugi causes a lot of
linking errors.
Interestingly enough, that was me who made OSL to use external pugi
to solve configuration problem. But now i can not reproduce that
anymore.
Ideally we would either link everything against our pugi, or not
compile it at all.
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 an issue with objects destructing in a non deterministic way during process shutdown, temporary work around this until osl has a fix in place.
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.
