Add round to even builtin for non DFP variables

IEEE arithmetic defines five rounding modes, described at

https://en.wikipedia.org/wiki/IEEE_floating_point#Rounding_rules

For DFP arithmetic these may already have been implemented, but for "nomal" fixed decimal arithmetic, they have to be user-implemented. It would be nice if at least one, "round-to-nearest, ties to even" could be added as a new builtin function.

    Delivered as part of APAR PI75582 / PTF UI44364

    The new ROUNDTOEVEN built-in function provides this support

    The ROUNDDEC built-in function has been renamed as ROUNDAWAYFROMZERO. This gives it a much more meaningful name since what it performs is mostly commonly known as round half away from zero.

    The ROUNDTOEVEN built-in function returns the value of x rounded at a digit specified by n following the rounding rule of round half to even.

    It is the same as the ROUNDAWAYFROMZERO function except that while that function rounds ties away from zero (so 24.5 gets rounded to 25 and -24.5 gets rounded to -25), the ROUNDTOEVEN function rounds ties to the nearest even value (so both 23.5 and 24.5 get rounded to 24 and both -23.5 and -24.5 get rounded to -24 )
