This patch is a result of auditing all of our uses of
get_datadir_fname() and its kin, and dividing them into cache vs
keys vs other data.
The new get_keydir_fname() and get_cachedir_fname() functions don't
actually do anything new yet.
Apparently, the unit tests relied on being able to make ed->x509
link certs even when they hadn't set any server flags in the
options. So instead of making "client" mean "never generate an
ed->x509 cert", we'll have it mean "it's okay not to generate an
ed->x509 cert".
(Going with a minimal fix here, since this is supposed to be a
stable version.)
Previously we could sometimes change our signing key, but not
regenerate the certificates (signing->link and signing->auth) that
were signed with it. Also, we would regularly replace our TLS x.509
link certificate (by rotating our TLS context) but not replace our
signing->link ed25519 certificate. In both cases, the resulting
inconsistency would make other relays reject our link handshakes.
Fixes two cases of bug 22460; bugfix on 0.3.0.1-alpha.
Our config code is checking correctly at DataDirectoryGroupReadable but then
when we initialize the keys, we ignored that option ending up at setting back
the DataDirectory to 0700 instead of 0750. Patch by "redfish".

Improve the messages logged when Tor wants or needs to load the master ed25519 identity key so the user is explicitly informed when further action is required or not. Fixes ticket #20650.
Some compilers apparently noticed that p2len was allowed to be equal
to msg, and so maybe we would be doing memset(prompt2, ' ', 0), and
decided that we probably meant to do memset(prompt2, 0, 0x20);
instead.
Stupid compilers, doing optimization before this kind of warning!
My fix is to just fill the entire prompt2 buffer with spaces,
because it's harmless.
Bugfix on e59f0d4cb9, not in any released Tor.
They are no longer "all" digests, but only the "common" digests.

This is an automated patch I made with a couple of perl one-liners:
perl -i -pe 's/crypto_digest_all/crypto_common_digests/g;' src/*/*.[ch]
perl -i -pe 's/\bdigests_t\b/common_digests_t/g;' src/*/*.[ch]
