There were a variety of potential 64b problems due to the complete lack of prototype declarations. So, we add a file, isam_prototypes.h, generated mostly by the 'cproto' tool. We also fixed up some errors that having proper prototypes pointed out, mainly in passing ints where pointers were expected and vice versa. The iserase() function was supposed to accept a char *, but was defined as only accepting a char. Fun stuff like that.
