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.

As of August 29, 2018, Appveyor images come with gcc 8.2.0 by
default. 64-bit Windows executables compiled with gcc 8.2.0 and
tor's --enable-gcc-hardening crash.
Fixes bug 27460; bugfix on 0.3.4.1-alpha.
It is not supported, and always fails. Some compilers warn about the
function pointer cast on 64-bit Windows.
Fixes bug 27461; bugfix on 0.2.2.23-alpha.
gcc 8 warns that extend_info_t.nickname might be truncated by strncpy().
But it doesn't know that nickname can either contain a hex id, or a
nicknames. hex ids are only used for general and HSDir circuits.
Fixes bug 27463; bugfix on 0.1.1.2-alpha.
