- on newer HTTPD versions, return connection monitoring
to the event MPM when block on client updates.
2.4.x versions still treat connections in the event
MPM as KeepAlive and purge them on load in the middle
of response processing.
- spelling fixes
- support for yield calls in c2 "network" filter

- provide "Connection" header in internal Upgrade request
- set input notification if input is already available when
stream processing is started
- add optional function in mod_http2.h to use instead of
ap_get_pollfd_from_conn() in older servers with a new
mod_http2

server versions. Give error message accordingly when trying to
enable websockets in unsupported configurations.
Add test and code to check the, finally selected, server of
a request_rec for websocket support or 501 the request.

described in RFC 8441. A new directive 'H2WebSockets on|off' has been
added. The feature is by default not enabled.
As also discussed in the manual, this feature should work for setups
using "ProxyPass backend-url upgrade=websocket" without further changes.
Special server modules for WebSockets will have to be adapted,
most likely, as the handling if IO events is different with HTTP/2.
HTTP/2 WebSockets are supported on platforms with native pipes. This
excludes Windows.

- New directive 'H2EarlyHint name value' to add headers to a response,
picked up already when a "103 Early Hints" response is sent. 'name' and
'value' must comply to the HTTP field restrictions.
This directive can be repeated several times and header fields of the
same names add. Sending a 'Link' header with 'preload' relation will
also cause a HTTP/2 PUSH if enabled and supported by the client.
- Fixed an issue where requests were not logged and accounted in a timely
fashion when the connection returns to "keepalive" handling, e.g. when
the request served was the last outstanding one.
This led to late appearance in access logs with wrong duration times
reported.
- Accurately report the bytes sent for a request in the '%O' Log format.
This addresses #203, a long outstanding issue where mod_h2 has reported
numbers over-eagerly from internal buffering and not what has actually
been placed on the connection.
The numbers are now the same with and without H2CopyFiles enabled.

* Extensive testing in production done by Alessandro Bianchi (@alexskynet)
on the v2.0.x versions for stability. Many thanks!
* refactored stream response handling to reflect the different phases
(response/data/trailers) more clearly and help resolving cpu busy loops.
* Adding more negative tests for handling of errored responses to cover
edge cases.
* mod_http2: fixed handling of response where neiter an EOS nor an ERROR was
received as a cause to reset the stream.
* mod_proxy_http2: generating error buckets for fault response bodies, to
signal failure to fron when response header were already sent.
v2.0.9
--------------------------------------------------------------------------------
* Fixed a bug where errors during reponse body handling did not lead to
a proper RST_STREAM. Instead processing went into an infinite loop.
Extended test cases to catch this condition.
v2.0.8
--------------------------------------------------------------------------------
* Delaying input setup of a stream just before processing starts. This allows
any EOS indicator arriving from the client before that to take effect.
Without knowing that a stream has no input, internal processing has to
simulate chunked encoding. This is not wrong, but somewhat more expensive
and mod_security has been reported to be allergic to seeing 'chunked'
on some requests. See <https://bz.apache.org/bugzilla/show_bug.cgi?id=66282>.
* mod_proxy_http2: fixed#235 by no longer forwarding 'Host:' header when
request ':authority' is known. Improved test case that did not catch that
the previous 'fix' was incorrect.

level of header checks as defined in the HTTP/2 RFCs. Default is 7540.
9113 activates the checks for forbidden leading/trailing whitespace in
field values (available from nghttp2 v1.50.0 on).
- source sync with github version
- fix for keepalive idle wait in mpm_worker setup
- ensuring EOS when secondary connection has been handled
- fixed race in late input EOS arrival when stream was
already scheduled for execution.

This replaces the internal H2_HEADERS bucket, removing its
source file and also obsoletes any interim response parsing
needs.

- adds new meta bucket types REQUEST, RESPONSE and HEADERS to the API.
- adds a new method for setting standard response headers Date and Server
- adds helper methods for formatting parts of HTTP/1.x, like headers and
end chunks for use in non-core parts of the server, e.g. mod_proxy
- splits the HTTP_IN filter into a "generic HTTP" and "specific HTTP/1.x"
filter. The latter one named HTTP1_BODY_IN.
- Uses HTTP1_BODY_IN only for requests with HTTP version <= 1.1
- Removes the chunked input simulation from mod_http2
- adds body_indeterminate flag to request_rec that indicates that a request
body may be present and needs to be read/discarded. This replaces logic
that thinks without Content-Length and Transfer-Encoding, no request
body can exist.

create_secondary_connection and ap_create_secondary_connection()
to setup connections related to a "master" one, as used in
the HTTP/2 protocol implementation.
*) mod_http2: using the new API calls to get rid of knowledge
about how the core handles conn_rec specifics.
Improvements in pollset stream handling to use less sets.
Using atomic read/writes instead of volatiles now.
Keeping a reserve of "transit" pools and bucket_allocs for
use on secondary connections to avoid repeated setup/teardowns.

loop when clients close connections prematurely.
Enhanced the scoreboard status updates on h2 connections for
mod_status. 'server-status' now gives a better idea what the
connection is working on.

the bytes reportded to mod_logio are counted specifically.

- Fixed an issue since 1.15.24 that "Server" headers in proxied requests
were overwritten instead of preserved. [PR by @daum3ns]
- Added directove 'H2StreamTimeout' to configure a separate value for HTTP/2
streams, overriding server's 'Timeout' configuration. [rpluem]
- HTTP/2 connections now use pollsets to monitor the status of the
ongoing streams and their main connection when host OS allows this.
- Removed work-arounds for older versions of libnghttp2 and checking
during configure that at least version 1.15.0 is present.
- The HTTP/2 connection state handler, based on an experiment and draft
at the IETF http working group (abandoned for some time), has been removed.
- H2SerializeHeaders no longer has an effect. A warning is logged when it is
set to "on". The switch enabled the internal writing of requests to be parsed
by the internal HTTP/1.1 protocol handler and was introduced to avoid
potential incompatibilities during the introduction of HTTP/2.
- Removed the abort/redo of tasks when mood swings lower the active limit.
