We previously used tor_fragile_assert() to declare that this case could not happen: VERSIONS cells are always supposed to be variable-sized, right? This is incorrect, though. On a v1 link protocol connection, all cells are fixed-sized. There aren't supposed to be any VERSIONS cells with this version of the protocol, but apparently, somebody was messing up. (The v1 link protocol is obsolete, so probably the implementer responsible didn't mean to be using it.) Fixes bug 31107. Bugfix on 0.2.4.4-alpha, when we introduced a tor_fragile_assert() for this case.

o Minor bugfixes (logging, protocol violations):

- Do not log a nonfatal assertion failure when receiving a VERSIONS

cell on a connection using the obsolete v1 link protocol. Log a

protocol_warn instead. Fixes bug 31107; bugfix on 0.2.4.4-alpha.
