If a tor client gets a descriptor that it can't decrypt, chances are that the
onion requires client authorization.
If a tor client is configured with client authorization for an onion but
decryption fails, it means that the configured keys aren't working anymore.
In both cases, we'll log notice the former and log warn the latter and the
rest of the decryption errors are now at info level.
Two logs statement have been removed because it was redundant and printing the
fetched descriptor in the logs when 80% of it is encrypted wat not helping.

This commit refactors the existing decryption code to make it compatible with
a new logic for when the client authorization is enabled.

The new ClientOnionAuthDir option is introduced which is where tor looks to
find the HS v3 client authorization files containing the client private key
material.

This commit won't build yet -- it just puts everything in a slightly
more logical place.
The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature". The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.
This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all. That
will have to come in the future.
We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
