0024234: occt master is not compiled by VC++ 2005 (vc8 32/64 bit TKBO)

Fixed building by VS 2005 and VS 2013 (Express):
- macro _WIN32_WINNT defined in BOPCol_TBB.hxx for building with TBB on VS 2005
- compiler warnings specific for VS 2005 (vc8) fixed (explicit casts added in assignment expressions involving small integer types)
- definition of functions atanh, acosh, asinh is avoided for vc12 and later (they are provided by CRT in vc12)
- math constants (M_PI and similar) are defined by including math.h rather than by custom code
- misuse of stream operator << fixed in a few places
