Ephemeral services will be listed in rend_services_list at the end of
rend_config_services, so it must check whether directory is non-NULL
before comparing.
This crash happens when reloading config on a tor with mixed configured
and ephemeral services.
Fixes bug #16060. Bugfix on 0.2.7.1-alpha.
With #15881 implemented, this adds the missing descriptor ID at the end of
the expected control message.

For FAILED and RECEIVED action of the HS_DESC event, we now sends back the
descriptor ID at the end like specified in the control-spec section 4.1.25.
Fixes#15881

This field was only needed to work with the now-long-gone (I hope,
except for some horrible apples) openssl 0.9.8l; if your headers say
you have openssl 1.1, you won't even need it.
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.
Use it in the sample_laplace_distribution function to make sure we return
the correct converted value after math operations are done on the input
values.
Thanks to Yawning for proposing a solution.

- Rewrite changes file.
- Avoid float comparison with == and use <= instead.
- Add teor's tor_llround(trunc(...)) back to silence clang warnings.
- Replace tt_assert() with tt_i64_op() and friends.
- Fix whitespace and a comment.
Consistently check for overflow in round_*_to_next_multiple_of.
Check all round_*_to_next_multiple_of functions with expected values.
Check all round_*_to_next_multiple_of functions with maximal values.
Related to HS stats in #13192.
Avoid division by zero.
Avoid taking the log of zero.
Silence clang type conversion warnings using round and trunc.
The existing values returned by the laplace functions do not change.
Add tests for laplace edge cases.
These changes pass the existing unit tests without modification.
Related to HS stats in #13192.
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.
