Mark Murray d79d4a7ced Major cleanup of eBones code:
- Get all functions prototyped or at least defined before use.
- Make code compile (Mostly) clean with -Wall set
- Start to reduce the degree to which DES aka libdes is built in.
- get all functions to the same uniform standard of definition:
int
foo(a, b)
int a;
int *b;
{
   :
}
- fix numerous bugs exposed by above processes.

Note - this replaces the previous work which used an unpopular function
 definition style.
