* boost::thread mostly gone... still need to get rid of once
everything compiles
* replace boost::call_once
* remove link-time dependency on boost::thread
* first pass at using async
* switch to using async everywhere
* - added -DBOOST_SYSTEM_NO_DEPRECATED to definitions for MINGW builds
- modified a few #ifdef's to discriminate better between MINGW and MSVC
- added a ios::binary to Code/GraphMol/FileParsers/testMolSupplier.cpp
(I already had to add some of those in the past to avoid the CR+LF issues on Windows)
- modified Code/GraphMol/FMCS/MaximumCommonSubgraph.cpp and
Code/GraphMol/FMCS/FMCS.h because checking the function pointer does not
work with DLLs as the function pointer changes upon different calls
- builds under MinGW with -DRDK_USE_BOOST_SERIALIZATION=OFF and
RDK_BUILD_THREADSAFE_SSS=OFF
* - added the possibility to define MSVC_RUNTIME_DLL to point to the
absolute path of an appropriate MSVC runtime DLL to enable
multi-threaded builds with MinGW
- modified C++ and Python tests of the multi-threaded conformation
embedder as under 32-bit MinGW lower numeric precision introduces minimal
coordinate differences with result in ~1-kcal energy difference.
Therefore the energy criterion has been made more lenient, and a
coordinate MSD criterion has been introduce to compare substantial
identity of conformations
* - reverted Code/GraphMol/DistGeomHelpers/Wrap/testDistGeom.py and Code/GraphMol/DistGeomHelpers/testDgeomHelpers.cpp
to the upstream/master version
