   *) core/mod_ssl/mod_md:
     - adding new ap_ssl_*() functions for a backward
       compatible replacement of the major optional mod_ssl functions. This
       allows other ssl modules to work without impersonating mod_ssl and
       also allows different ssl modules being active on separate ports.
     - latest mod_md with support for multiple certificates per domain
       and ECDSA certificates. Removed ACMEv1 support.
     - Interworking mod_md and ssl modules changed to exchange PEM strings
       instead of file paths for ACME challenges.
     - core/mod_ssl/mod_md: adding OCSP response provisioning as core feature.

  *) mod_http2: sync with github standalone version 1.15.17
     - Log requests and sent the configured error response in case of early detected
       errors like too many or too long headers. [Ruediger Pluem]
     - new option 'H2OutputBuffering on/off' which controls the buffering of stream output.
       The default is on, which is the behaviour of older mod-h2 versions. When off, all
       bytes are made available immediately to the main connection for sending them
       out to the client. This fixes interop issues with certain flavours of gRPC, see
       also <https://github.com/icing/mod_h2/issues/207>.

Be defensive when calculating the digest. Make sure the offset is initialised

Seek to the start of the file when calculating the ETag.

mod_http2: explicitely apr_thread_exit() at the end of slot_run().

Calling apr_thread_exit() before returning from the thread function avoids
leaking the thread's pool (until/unless APR-2.0 is used).

mod_http2: Fix workers synchronization on pchild cleanup.

When the MPM child exits and pre-workers_pool_cleanup() is called, all the
workers are not necessarily in their idle critical section, thus aborting slots
in the ->idle list only may leave worker threads alive, later blocked in the
idle critical section with no one to wake them.

Instead of the per-slot ->aborted flag, workers_pool_cleanup() will now set
workers->aborted "globally" such that slot_run() does not wait to be woken up
from idle in this case, and all workers really exit.

Also, for workers_pool_cleanup() to wait for all the workers to reach the
->zombies list before returning, a new ->all_done condition variable is armed
when the last thread exits. Since this depends on the atomic ->worker_count to
reach zero, for accuracy the increment in activate_slot() is moved before the
thread startup.

* modules/http2/h2_workers.h (struct h2_workers): volatilize ->aborted and
  add the ->all_done condition variable.

* modules/http2/h2_workers.c (push_slot, pop_slot): volatilize the h2_slot*
  being cas-ed.

* modules/http2/h2_workers.c (cleanup_zombies): rename to join_zombies(), and
  move ->worker_count atomic inc to slot_done().

* modules/http2/h2_workers.c (get_next): when workers->aborted, leave and don't
  wait for ->not_idle. Return an int/bool since it's gotten / not gotten.

* modules/http2/h2_workers.c (slot_done): signal ->all_done when the last
  worker and the MPM child are exiting.

* modules/http2/h2_workers.c (slot_run): rework the loops now that get_next()
  is the stop signal.

* modules/http2/h2_workers.c (workers_pool_cleanup): wait for ->all_done when
  needed, and remove the !workers->aborted condition since the cleanup will
  only be called once.

* modules/http2/h2_workers.c (activate_slot): move ->worker_count atomic inc
  before the thread creation and handle failure rollback.
