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.

leading/trailing whitespace (space +htab) before being processed
or send in a response. This is compatible behaviour to HTTP/1.1
parsers that strip incoming headers of such characters.

- removed intermittent "H2HeaderStrictness" directive again.

* 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.

- 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.

* silencing gcc uninitialized warning
* refrainning from apr_table_addn() use since pool debug assumptions are in conflict
* adding more assertions
* copy-porting changes to base64 encoding code from mod_md

mod_http2: removing comments that documented that greenbytes has untransferable copyright to the sources. The rights, of course, remain unaffected, but maybe some people can sleep better.

mod_http2: disable and give warning when mpm_prefork is encountered.
The server will continue to work, but HTTP/2 will no longer be negotiated.

mod_http2: fixed possible deadlock that could occur when connections were
terminated early with ongoing streams. Fixed possible hanger with timeout
on race when connection considers itself idle.

mod_http2: only when 'HttpProtocolOptions Unsafe' is configured, will
control characters in response headers or trailers be forwarded to the
client. Otherwise, in the default configuration, a request will eiher
fail with status 500 or the stream will be reset by a RST_STREAM frame.

mod_http2 after review by Christophe:

mod_http2: h2 workers with improved scalability for better scheduling
performance. There are H2MaxWorkers threads created at start and the
number is kept constant.
