[PATCH 04/25] verify_internal_event: preserve constness of data pointer

[Alan Coopersmith]

All we're using it for is ErrorF calls, so make it a const char *
to stop gcc from warning:

inpututils.c: In function 'verify_internal_event':
inpututils.c:629:9: warning: cast discards qualifiers from pointer target type
