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 moved the crypto_pk_* digest functions into crypto_rsa.[ch] because they fit
better with the RSA module.
Follows #24658.

Also correct MAX_VERSIONS_TO_EXPAND to match the C.
NOTE that this patch leads to incorrect behavior: the C code allows
huge ranges; it just doesn't allow votes on them (currently). For
full compatibility, we'll need to make the rust code store ranges as
ranges natively, possibly using something like the range_map crate.
Still, this patch is smaller than a "proper" fix.
Fixes TROVE-2018-003.
Since 0.2.4, tor uses EWMA circuit policy to prioritize. The previous
algorithm, round-robin, hasn't been used since then but was still used as a
fallback.
Now that EWMA is mandatory, remove that code entirely and enforce a cmux
policy to be set.
This is part of a circuitmux cleanup to improve performance and reduce
complexity in the code. We'll be able to address future optimization with this
work.
Closes#25268

The reason to do so is because these functions haven't been used in years so
since 0.2.4, every callsite is NOP.
In future commits, we'll remove the round robin circuit policy which is mostly
validated within those function.
This simplifies the code greatly and remove dead code for which we never had a
configure option in the first place nor an easy way to use them in production.

It is rename to something more meaningful that explains what it does exactly
which is sets the EWMA options (currently only one exists). The new name is
cmux_ewma_set_options().
Also, remove a public function from circuitmux_ewma.h that is only used in the
C file. Make it static inline as well.
