0bc1241494 Make sure that we send at least some random data in RELAY_DATA cells 
Proposal 289 prevents SENDME-flooding by requiring the other side to
authenticate the data it has received.  But this data won't actually
be random if they are downloading a known resource.  "No problem",
we said, "let's fell the empty parts of our cells with some
randomness!" and we did that in #26871.

Unfortunately, if the relay data payloads are all completely full,
there won't be any empty parts for us to randomize.

Therefore, we now pick random "randomness windows" between
CIRCWINDOW_INCREMENT/2 and CIRCWINDOW_INCREMENT. We remember whether we have
sent a cell containing at least 16 bytes of randomness in that window.  If we
haven't, then when the window is exhausted, we send one.  (This window approach
is designed to lower the number of rng checks we have to do.  The number 16 is
pulled out of a hat to change the attacker's guessing difficulty to
"impossible".)

Implements 28646.

7893f2cd73 cov-test-determinism: use the same RNG seed as in travis.yml 
We added this facility so that we could get deterministic PRNG
behavior for coverage testing on tests that use a replaced PRNG.
We need to have our coverage determinism tool test for this as well.

3835a3acf5 sendme: Properly record SENDMEs on both edges 
Turns out that we were only recording the "b_digest" but to have
bidirectionnal authenticated SENDMEs, we need to use the "f_digest" in the
forward cell situation.

Because of the cpath refactoring, this commit plays with the crypt_path_ and
relay_crypto_t API a little bit in order to respect the abstractions.

Previously, we would record the cell digest as the SENDME digest in the
decrypt cell function but to avoid code duplication (both directions needs to
record), we now do that right after iff the cell is recognized (at the edge).
It is now done in circuit_receive_relay_cell() instead.

We now also record the cell digest as the SENDME digest in both relay cell
encryption functions since they are split depending on the direction.
relay_encrypt_cell_outbound() and relay_encrypt_cell_inbound() need to
consider recording the cell digest depending on their direction (f vs b
digest).

Fixes #30428

59b9eecc19 sendme: Record cell digest on both client and exit 
It turns out that only the exit side is validating the authenticated SENDME v1
logic and never the client side. Which means that if a client ever uploaded
data towards an exit, the authenticated SENDME logic wouldn't apply.

For this to work, we have to record the cell digest client side as well which
introduced a new function that supports both type of edges.

This also removes a test that is not valid anymore which was that we didn't
allow cell recording on an origin circuit (client).

5f47d582d5 Practracker beatings are even more fun when they get caused mid-PR due to a github auto-rebase of a PR 
Because github PRs choose the most recent origin/master at the time of the PR
(and for any fixups pushed to a PR later to send to CI), there are tons of
conflicts and unexpected practracker issues.

This means CI can suddenly fail after fixups to a branch that pass locally.

Then CI fails and we have to close and re-open the PR.

dbfe1a14e4 When parsing a multiline controller command, be careful with linebreaks 
The first line break in particular was mishandled: it was discarded
if no arguments came before it, which made it impossible to
distinguish arguments from the first line of the body.

To solve this, we need to allocate a copy of the command rather than
using NUL to separate it, since we might have "COMMAND\n" as our input.

Fixes ticket 29984.
