[PATCH 03/25] Use const cast in BitIsOn macro to avoid angering gcc

[Alan Coopersmith]

Fixes gcc warnings such as:
inpututils.c: In function 'valuator_mask_isset':
inpututils.c:498:5: warning: cast discards qualifiers from pointer target type
inpututils.c: In function 'CountBits':
inpututils.c:613:9: warning: cast discards qualifiers from pointer target type
