OpenSSL 1.1.0 must be built with "enable-deprecated", and compiled with
`OPENSSL_USE_DEPRECATED` for this to work, so instead, use the newer
routine as appropriate.
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.
"+HSPOST" and the related event changes allow the uploading of HS
descriptors via the control port, and more comprehensive event
monitoring of HS descriptor upload status.
When we have a new descriptor ID for an onion address request, change it in
the rend_data_t object and purge the old one from the last hid serv request
cache.

Stop using an onion address since it's not indexed with that anymore in the
last hid serv request cache. Instead use a base32 encoded descriptor ID
contained in the rend_data_t object.

Every callsite that use to allocate a rend_data_t object now use the
rend_data_client/service_create() function.

Ground works for fixing #15816. This adds the rend_data_create() function in
order to have a single place where we initialize that data structure.
Furthermore, an array of descriptor IDs is added (one per replica) so we can
keep a copy of the current id in the object. It will be used to purge the
last hid serv request cache using those descriptor IDs. When they change,
they will be replaced and the old ones will be purged from the cache.

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.

These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.
Implements #6411.
