Hello,

Accomplishments:

1. Add more test vectors to skein_256 and skein_512.

https://github.com/magnumripper/JohnTheRipper/pull/1649/files

2. Fix: is_key_right() ignores the result of get_key() when invoked by
the test_fmt_case(). Check the length of string returned by get_key()
which should be between plaintext_min_length and plaintext_length.

3. Add test vector for vms to detect different code path.

4. Try to debug the bitcoin crash when ./john --test-full=0. Now we
can reproduce this bug with wordlist mode. Opened an issue for
this bug.
