fixed: TTMATH_DEBUG_LOG has generated different carry-flags in UInt<> (when TTMATH_NOASM was used)

fixed: some GCC warnings about uninitialized variables
added: macro TTMATH_BIG_DEFAULT_CLEAR
       when defined the default constructor from Big<> clears its mantissa and exponent
       Big<1, 2> var;
       var.mantissa and var.exponent will be set to zero
       (but var has the NaN flag set too - it is not zero value, this is mainly for debug purposes)
added: Big::SetZeroNan()
       this method sets NaN flag (Not a Number)
       also clears the mantissa and exponent (similarly as it would be a zero value)
