There was a nonfatal assertion in pathbias_should_count that would
trigger if onehop_tunnel was set, but the desired_path_length was
greater than 1. This patch fixes that. Fixes bug 24903; bugfix on
0.2.5.2-alpha.
Because of #25306 for which we are unable to reproduce nor understand how it
is possible, this commit removes the asserts() and BUG() on the missing
descriptors instead when rotating them.
This allows us to log more data on error but also to let tor recover
gracefully instead of dying.

This patch adds some additional logging to circuits_handle_oom() to give
us more information about which specific compression backend that is
using a certain amount of memory.

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.)
* FIXES#25450: https://bugs.torproject.org/25450
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.
since all it does is produce false positives
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.
