patch.
- Adds timeout to entropy collection
- Disables slow entropy sources
- Load and save seed file
- Changed entropy seed code to user per-user seeds only (server seed is
saved in root's .ssh directory)
- Use atexit() and fatal cleanups to save seed on exit
- All OpenSSL includes are now unconditionally referenced as
openssl/foo.h
- Pick up formatting changes
- Other minor changed (typecasts, etc) that I missed
