Coverity found a null pointer reference in nodelist_add_microdesc().
This is almost certainly impossible assuming that the routerstatus_t
returned by router_get_consensus_status_by_descriptor_digest() always
corresponds to an entry in the nodelist. Fixes bug 25629.

This should avoid most intermittent test failures on developer and CI machines,
but there could (and probably should) be a more elegant solution.
Also, this test was testing that the IP was created and its expiration time was
set to a time greater than or equal to `now+INTRO_POINT_LIFETIME_MIN_SECONDS+5`:
/* Time to expire MUST also be in that range. We add 5 seconds because
* there could be a gap between setting now and the time taken in
* service_intro_point_new. On ARM, it can be surprisingly slow... */
tt_u64_op(ip->time_to_expire, OP_GE,
now + INTRO_POINT_LIFETIME_MIN_SECONDS + 5);
However, this appears to be a typo, since, according to the comment above it,
adding five seconds was done because the IP creation can be slow on some
systems. But the five seconds is added to the *minimum* time we're comparing
against, and so it actually functions to make this test *more* likely to fail on
slower systems. (It should either subtract five seconds, or instead add it to
time_to_expire.)

The C code and the rust code had different separate integer overflow
bugs here. That suggests that we're better off just forbidding this
pathological case.
Also, add tests for expected behavior on receiving a bad protocol
list in a consensus.
Fixes another part of 25249.
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.
In some cases we had checked for it, but in others we had not. One
of these cases could have been used to remotely cause
denial-of-service against directory authorities while they attempted
to vote.
Fixes TROVE-2018-001.

this commit should get merged into 0.2.9 and 0.3.0 *and* 0.3.1, even
though the code in the previous commit is already present in 0.3.1. sorry
for the mess.

This commit takes a piece of commit af8cadf3a9 and a piece of commit
46fe353f25, with the goal of making channel_is_client() be based on what
sort of connection handshake the other side used, rather than seeing
whether the other side ever sent a create_fast cell to us.
We had this safeguard around dos_init() but not when the consensus changes
which can modify consensus parameters and possibly enable the DoS mitigation
even if tor wasn't a public relay.
