Crypto modularity proj: Separate files under crypto directory based on their functionality. Move Kerberos specific files into krb subdir and MIT specific - into builtin subdir. Place all tests into crypto_tests subfolder.

+ * output file will be diffed against expected output to see whether
+ * regression tests pass.  The input file has a very primitive format.
+ * It is composed of alternating seeds and outputs.  The first line in
+ * the file is an integer source id from the krb5_c_randsource enum in
+ * krb5.h.  Then an integer seed length is read.  Then that many bytes
+ * (encoded in hex) are read; whitespace or newlines may be inserted
+ * between bytes.  Then after the seed data is an integer describing
+ * how many bytes of output should be written.  Then another source ID
+ * and seed length is read.  If the seed length is 0, the source id is
+ * ignored and the seed is not seeded.
