Return a newly allocated fake client authorization object instead of taking
the object as a parameter.

When reloading tor, check if our the configured client authorization have
changed from what we previously had. If so, republish the updated descriptor.

Previously, the validation by decoding a created descriptor was disabled
because the interface had to be entirely changed and not implemented at the
time.
This commit re-enabled it because it is now implemented.

Parse the client authorization section from the descriptor, use the client
private key to decrypt the auth clients, and then use the descriptor cookie to
decrypt the descriptor.

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

Because this secret data building logic is not only used by the descriptor
encoding process but also by the descriptor decoding, refactor the function to
take both steps into account.

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.

Previously, we encrypted the descriptor without the descriptor cookie. This
commit, when the client auth is enabled, the descriptor cookie is always used.
I also removed the code that is used to generate fake auth clients because it
will not be used anymore.

We need to generate all the related keys when building the descriptor, so that
we can encrypt the descriptor.

In order to switch the default HS version from 2 to 3, we need tor to be smart
and be able to decide on the version by trying to load the service keys during
configuration validation.

Part of #27215, we need to call the ed_key_init_from_file function during
option_validate() which is before the global_options variable is set.
This commit make ed_key_init_from_file() stop using get_options() and instead
now has a or_options_t parameter.

This is another attempt to fix 1437668. The assertion here should
be safe, since the rules of networkstatus_get_param() keep the value
it returns in range.
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.
