Hacky kludge fixes to get mingw64 to compile - "finite()" issues

* finite() is not defined on mingw64 when using c++11

* isfinite() can be used instead, but, to use it, you need to
#include <cmath> and using std::isfinite;
to each offending file where finite() may get called,
which is basically every file that includes
BLI_math.h ==> math_vector_inline.c

* In this patch, we define our own wrapper for finite() (via the
C code in blenlib, which is free of all this C++ crapiness),
which the C++ code can then feast on.

The name though needs 2 underscores, as the single-underscore
version (_finite) causes conflicts with symbols from dll's
(i.e. most likely conflicting with the MSVC _finite(), which
mingw-C++11 *still* doesn't see either).
