*) 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>.
"[mod_dav_fs etag handling] should really honor the FileETag setting".
- It now does.
- Add "Digest" to FileETag directive, allowing a strong ETag to be
generated using a file digest.
- Add ap_make_etag_ex() and ap_set_etag_fd() to allow full control over
ETag generation.
- Add concept of "binary notes" to request_rec, allowing packed bit flags
to be added to a request.
- First binary note - AP_REQUEST_STRONG_ETAG - allows modules to force
the ETag to a strong ETag to comply with RFC requirements, such as those
mandated by various WebDAV extensions.
Be defensive when the request is missing.
Remove tabs.
Use a dedicated constant for the base64 sha1 length.
Be defensive when calculating the digest. Make sure the offset is initialised
to zero before reading the current offset.
Seek to the start of the file when calculating the ETag.
Add log numbers to util_etag.c.
Add MMAP support to ETag generation.
Use a brigade instead of direct reads, allow APR to handle MMAP.

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.

wait for ->not_idle. Return an int/bool since it's gotten / not gotten.

worker and the MPM child are exiting.

* modules/ssl/ssl_engine_io.c (ssl_io_filter_coalesce): Handle the case
where apr_bucket_read fails with an error and hence our current bucket
remains the morphing bucket and is not replaced with a 'data' bucket.
If the error is not EAGAIN, error out with an AP_FILTER_ERROR,
otherwise just do not consider the morphing bucket that has no data for
coalesce.
* modules/ssl/ssl_engine_io.c (ssl_io_filter_coalesce): Further tweaks
to logic, comments and debugging:
- allow buffering up to exactly COALESCE_BYTES rather than COALESCE_BYTES-1.
- put bucket type name in logging output
- do not coalesce a single-bucket prefix of length equal to the
buffer size (which would be a pointless memory copy).

mod_proxy_hcheck: don't pile up health checks. PR 63010.
Prevent health checks from running for a worker until the last one is fully
finished, to avoid making things worse (memory growth, #connections, ..).
This is done by zeroing worker->s->updated before scheduling the worker in the
threadpool, and resetting the time when it's finished. The scheduler then does
nothing if worker->s->updated is zero.
Also, to save some apr_time_now() calls when !HC_USE_THREADS, *baton->now is
updated in the callback and reused by the scheduler.

unrecognized schemes (overlong or not) and be caught by the no-handler case
