dc6d7f072d Make foo_validate() functions call config_validate().
The former foo_validate() functions are now toplevel
legacy_validate_fn callbacks.  The new foo_validate() functions now
call them.

This change lets us remove the old shared_random disk state
validation callback entirely.

simplification is guaranteed to be correct.  Full boolean
simplification would require this script to parse C, and nobody

bcef6a5802 practracker: Refactor flow to use generators
Instead of having "consider" functions that have to call a global

f306d12b58 Refactor handling of TestingTorNetwork
Previously, when TestingTorNetwork was set, we would manually adjust
the initvalue members of a bunch of other config_var_t, and then
re-run the early parts or parsing the options.

Now we treat the initvalue fields as immutable, but instead assign
to them in options_init(), as early as possible.  Rather than
re-running the early parts of options, we just re-call the
options_init_from_string() function.

This patch de-kludges some of our code pretty handily.  I think it
could later handle authorities and fallbacks, but for now I think we
should leave those alone.

When an exception is present, we can now violate the limit by a little
bit and only produce a warning.  The strict flag overrides this
behavior.

Also, practracker counted functions as starting one line after the
function name, and ending with the closing brace.  Now they start
with the open brace and end with the closing brace.

c60a85d22a Add a "typed_var" abstraction to implement lvalue access in C.
Right now, this has been done at a high level by confparse.c, but it
makes more sense to lower it.

This API is radically un-typesafe as it stands; we'll be wrapping it
in a safer API as we do #30914 and lower the struct manipulation
code as well.

Closes ticket 30864.

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.

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
