These are the start of a lot of work to clean up the FreeBSD eBones code. these changes include, but are not limited to: - Create prototypes for all the library routines - Make all the libraries compile clean with -Wall set - Fix numerous small bugs shown up in the above process - Prepare the code for libdes's removal to secure/ - add register, registerd and make_keypair to the make Lots more will follow in days to come.
