markm a83b802bad Start the eBones cleanup ball rolling.
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.
