Support universal C runtime, SDK 10 and .NET 4.6

Starting with MSVC 14.0 (aka VS 2015) C Runtime (CRT) was divided in
two logical parts: The VCRuntime, which contained the compiler support
functionality required for things like process startup and exception
handling, and a "stable" part that contained all of the purely library
parts of the CRT.

Previously, all of the CRT headers, sources, and libraries were
distributed as part of the Visual C++ SDK, installed in the VC
subdirectory of Visual Studio installation (generally C:\Program
Files (x86)\Microsoft Visual Studio 14.0\VC). The files for the
VCRuntime are still part of the Visual C++ SDK. The headers, sources,
and libraries are now distributed as part of a separate Universal CRT
SDK. This SDK is included with Visual Studio; it is installed to
C:\Program Files (x86)\Windows Kits\10. The debug ucrtbased.dll is
also included as part of this SDK and is installed to the system
directory.

In I0ef8cda7b initial support was added to suport VS 2015. In this
change support for universal CRT, .NET 4.6 and SDK 10 is added. UCRT
dirs are added to CFLAG, CXXFLAG and ILIB. SDK 10 include path is
added to SOLARINC. .NET Framework 4.6 was splitted from SDK 10 and
needs to be discovered separately.
