Move the mostly-invariant part of control_event_boostrap() into a
helper control_event_bootstrap_core(). The helper doesn't modify any
state beyond doing logging and control port notifications.
Simplify control_event_bootstrap() by making it return void again. It
is currently a fairly complicated function, and it's made more
complicated by returning an int to signal whether it logged at NOTICE
or INFO.
The callers conditionally log messages at level NOTICE based on this
return value. Change the callers to unconditionally log their verbose
human-readable messages at level INFO to keep NOTICE logs less
cluttered.
This partially reverts the changes of #14950.
This is an attempt to work around what I think may be a bug in
OSS-Fuzz, which thinks that uninitialized data might be passed to
the curve25519 functions.
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.

This commit tests that the descriptor building result, when the client
authorization is enabled, includes everything that is needed.

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