    mesa,glsl: Move round_to_even() from glsl to mesa/main (v2)

    Move round_to_even's definition to mesa/main so that _mesa_float_to_half()
    can use it in order to eliminate rounding bias.

    In additon to moving the fuction definition, prefix its name with "_mesa",
    just as all other functions in mesa/main are prefixed.

    v2: Fix Android build.
