re-write the handling of crypto libraries. try to use the one of

openssl's libcrypto or krb4's libdes that has all the required functionality (md4, md5, sha1, des, rc4). if there is no such library, the included lib/des is built. git-svn-id: svn://svn.h5l.se/heimdal/trunk/heimdal@10519 ec53bebd-3082-4978-b11e-865c3cabbd6b
