httpd: fix CVE-2019-9517 CVE-2019-10081 CVE-2019-10082 CVE-2020-1927 CVE-2020-1934

From a6c8c61510eea98f31961e8220bce4f07f928fd2 Mon Sep 17 00:00:00 2001
From: Stefan Eissing <icing@apache.org>
Date: Wed, 13 Mar 2019 15:00:57 +0000
Subject: [PATCH 4/5] Merge of
1849296,1852038,1852101,1852339,1853171,1853967,1854365,1854963,1854964,1855295,1855411
from trunk:
*) mod_http2: when SSL renegotiation is inhibited and a 403 ErrorDocument is
in play, the proper HTTP/2 stream reset did not trigger with H2_ERR_HTTP_1_1_REQUIRED.
Fixed. [Michael Kaufmann]
*) mod_http2: new configuration directive: `H2Padding numbits` to control
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]
*) mod_http2/mod_proxy_http2: proxy_http2 checks correct master connection aborted status
to trigger immediate shutdown of backend connections. This is now always signalled
by mod_http2 when the the session is being released.
proxy_http2 now only sends a PING frame to the backend when there is not already one
in flight. [Stefan Eissing]
*) mod_proxy_http2: fixed an issue where a proxy_http2 handler entered an infinite
loop when encountering certain errors on the backend connection.
See <https://bz.apache.org/bugzilla/show_bug.cgi?id=63170>. [Stefan Eissing]
*) mod_http2: Configuration directives H2Push and H2Upgrade can now be specified per
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]
