2b27ce52d2 Fix out-of-bounds read in INTRODUCE2 client auth
The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.

Fixed by checking auth_len before comparing the descriptor cookie
against known clients.

Fixes #15823; bugfix on 0.2.1.6-alpha.

26c344a563 Revert "Remove obsolete workaround in dirserv_thinks_router_is_hs_dir()"
Fixes #15850, part of #15801. Change file is added by this commit. The
original comment in the reverted commit is removed because right now we
*need* a DirPort until #15849 is implemented so no doubt nor confusion there
anymore.

This reverts commit 80bed1ac96.
