New directive `H2MaxStreamErrors` to control how much bad behaviour
by clients is tolerated before the connection is closed.

- Fixed bug in handling over long response headers. When the 64 KB limit
of nghttp2 was exceeded, the request was not reset and the client was
left hanging, waiting for it. Now the stream is reset.
- Added new directive `H2MaxHeaderBlockLen` to set the limit on response
header sizes.
- Fixed handling of Timeout vs. KeepAliveTimeout when first request on a
connection was reset.

of HTTP/2 requests in a forward proxy configuration.
General forward proxying is enabled via `ProxyRequests`. If the
HTTP/2 protocol is also enabled for such a server/host, this new
directive is needed in addition.

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.

amount of response body bytes put into a single HTTP/2 DATA frame.
Setting this to 0 places no limit (but the max size allowed by the
protocol is observed).
The module, by default, tries to use the maximum size possible, which is
somewhat around 16KB. This sets the maximum. When less response data is
available, smaller frames will be sent.

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.
git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1904777 13f79535-47bb-0310-9956-ffa450edef68
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.

- O(1) cost at registration of connection processing producers
- no limit on registered producers
- join of ongoing work on unregister
- callbacks to unlink dependencies into other h2 code
- memory cleanup on workers deactivation (on idle timeouts)
- idle_limit as apr_time_t instead of seconds

- 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.

- logio: improvements to reporting of sent bytes for http2 responses
- directive H2OutputBuffering, controls if any output should be sent immediately.

padding of HTTP/2 payload frames. 'numbits' is a number from 0-8,
controlling the range of padding bytes added to a frame. The actual number
added is chosen randomly per frame. This applies to HEADERS, DATA and PUSH_PROMISE
frames equally. The default continues to be 0, e.g. no padding. [Stefan Eissing]
*) mod_http2: ripping out all the h2_req_engine internal features now that mod_proxy_http2
has no more need for it. Optional functions are still declared but no longer implemented.
While previous mod_proxy_http2 will work with this, it is recommeneded to run the matching
versions of both modules. [Stefan Eissing]
*) mod_proxy_http2: changed mod_proxy_http2 implementation and fixed several bugs which
resolve PR63170. The proxy module does now a single h2 request on the (reused)
connection and returns. [Stefan Eissing]

Location/Directory, e.g. disabling PUSH for a specific set of resources. [Stefan Eissing]
*) mod_http2: HEAD requests to some module such as mod_cgid caused the stream to
terminate improperly and cause a HTTP/2 PROTOCOL_ERROR.
Fixes <https://github.com/icing/mod_h2/issues/167>. [Michael Kaufmann]

Get the help(er) of mod_http2 to determine how much connections should
be handled in the reslist by default (i.e. max_threads).

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: streaming of request output now reacts timely to data
from other streams becoming available. Same for new incoming requests.

mod_http2: adding support for MergeTrailers directive.
mod_http2: limiting DATA frame sizes by TLS record sizes in use on the
connection. Flushing outgoing frames earlier.
