be0891667e Fix undefined behavior caused by memory overlap
The tor_cert_get_checkable_sig function uses the signing key included in
the certificate (if available) when a separate public key is not given.

When the signature is valid, the tor_cert_checksig function copies the
public key from the checkable structure to the public key field of the
certificate signing key.

In situations where the separate public key is not given but the
certificate includes a signing key, the source and destination pointers
in the copy operation are equal and invoke undefined behavior.

Undefined behaviour is avoided by ensuring both pointers are different.

3fcb74e98b Add more consistency checks in load_ed_keys
Make sure that signing certs are signed by the right identity key,
to prevent a recurrence of #16530.  Also make sure that the master
identity key we find on disk matches the one we have in RAM, if we
have one.

This is for #16581.

3bee74c6d1 Generate weird certificates correctly
(Our link protocol assumes that the link cert certifies the TLS key,
and there is an RSA->Ed25519 crosscert)

0b819a2a7c Enforce more correspondence between ri and ei
In particular, they have to list the same ed25519 certificate, and
the SHA256 digest of the ei needs to match.

fe5d2477aa Implement ed25519-signed descriptors
Now that we have ed25519 keys, we can sign descriptors with them
and check those signatures as documented in proposal 220.

818e6f939d prop220: Implement certificates and key storage/creation
For prop220, we have a new ed25519 certificate type. This patch
implements the code to create, parse, and validate those, along with
code for routers to maintain their own sets of certificates and
keys.  (Some parts of master identity key encryption are done, but
the implementation of that isn't finished)
