tor-keymgr: ephemeral type validation

Closes #1917

See merge request !2917

tor-keymgr: BREAKING: Fix TODO: Refactor API: Keystore::insert

See merge request !2902

Drop redundant/unused param item_type: &KeystoreItemType from
keystore::Keystore::insert. Method now uses param
key: &dyn EncodableItem to obtain a KeystoreItemType

doc: Remove dead reference to rpc_demo.py

See merge request !2913

python: Add .gitignore

See merge request !2914

arti: Fix TODO:  Add test for onion_proxy::build_list

See merge request !2896

Motivation: Param _item_type is redundant since prev commit. No point
in checking if key_data's item type and _item_type are the same, we
do things as per key_data's item type from now on.

- Removes a test for item type validation.

Makes param item_type redundant. Renames item_type -> _item_type.

shadow: Capture only 40 bytes of packets

See merge request !2916

The pcaps are only used to check for leaks by reading the packet
source/destination, so we don't need the entire packet. This should make
CI artifacts a bit smaller.

The fixed-size portion of an IP header is 20 bytes for IPv4 and 40 bytes
for IPv6. Shadow doesn't support IPv6, but used the IPv6 header size
anyways.

tor-proto/tor-circmgr: remove "ntor_v3" feature flag (and always enable)

ntor v3 is now always enabled.

This commit adds a Python .gitignore to the `python/` directory, taking
from the public domain gitignore file provided by GitHub[1].

Previously, I saw a `__pycache__` in my `git status` which was not nice.

[1]: https://github.com/github/gitignore/blob/main/Python.gitignore

It was removed in 08847ab2.

Add some allow(unused)

tor-rtcompat: Avoid wildcard dependency requirements.

See merge request !2910

This is preventing us from publishing `tor-rtcompat`:

> error: failed to publish to registry at https://crates.io
>
> Caused by:
>   the remote server responded with an error (status 400 Bad Request): wildcard (`*`) dependency constraints are not allowed on crates.io. Crate with this problem: `hex` See https://doc.rust-lang.org/cargo/faq.html#can-libraries-use--as-a-version-for-their-dependencies for more information

Version bumps for the 1.4.2 release

See merge request !2906

Bump to today's latest - 24343d0ef1da38e2e9fe6684bdffe3cf32c1153d.
Primarily to get determinism fix
https://github.com/shadow/shadow/pull/3542.

Previously shadow would report a platform of "shadowsys" in the uname
syscall, which would cause chutney to disable sandboxing by default.

As of https://github.com/shadow/shadow/pull/3442, shadow now returns
"Linux", which causes the chutney default to enable sandboxing.

When sandboxing is enabled, the tor processes abort with error, since
shadow doesn't support the seccomp syscall.
