Nick Mathewson a83650852d Add another NULL-pointer fix for protover.c.
This one can only be exploited if you can generate a correctly
signed consensus, so it's not as bad as 25074.

Fixes bug 25251; also tracked as TROVE-2018-004.

o Minor bugfixes (denial-of-service):
- Fix a possible crash on malformed consensus. If a consensus had
contained an unparseable protocol line, it could have made clients
and relays crash with a null-pointer exception. To exploit this
issue, however, an attacker would need to be able to subvert the
directory-authority system. Fixes bug 25251; bugfix on
0.2.9.4-alpha. Also tracked as TROVE-2018-004.
