Use srandom() to init the PRNG, not srand(), since we use random().
This is harmless because srandom() is called somewhere else, with time(NULL)
as a seed, but this is more correct.

On FreeBSD just use the MD5 implementation of libmd rather than that of
libcrypto so we don't need to relinquish csup when world is built without
OpenSSL.

In usr.bin/csup/auth.c, cast time_t to intmax_t instead, and use the
corresponding printf length modifier.

shared secret, and use long long format to snprintf a time_t.

- Move csup away from contrib/ and into usr.bin/. Software is no longer
contributed, and main development is happening in the FreeBSD repo.

Suggested by: joel

- Add support for CVSup authentication mechanisms to csup.
- Include a cpasswd script performing the same mechanisms as the cvpasswd
utility from CVSup.
