lib/krb5/crypto.c was a large, monolithic block of code which made it very difficult to selectively enable and disable particular alogrithms. Reorganise crypto.c into individual files for each encryption and salt time, and place the structures which tie everything together into their own file (crypto-algs.c) Add a non-installed library (librfc3961) and test program (test_rfc3961) which builds a minimal rfc3961 crypto library, and checks that it is usable.
