Remove unneccesary casts from WriteToClient calls

 Casting return to (void) was used to tell lint that you intended
 to ignore the return value, so it didn't warn you about it.

 Casting the third argument to (char *) was used as the most generic
 pointer type in the days before compilers supported C89 (void *)
 (except for a couple places it's used for byte-sized pointer math).
