Fixes the following security issues:
*) SECURITY: CVE-2021-44790: Possible buffer overflow when parsing
multipart content in mod_lua of Apache HTTP Server 2.4.51 and
earlier (cve.mitre.org)
A carefully crafted request body can cause a buffer overflow in
the mod_lua multipart parser (r:parsebody() called from Lua
scripts).
The Apache httpd team is not aware of an exploit for the
vulnerabilty though it might be possible to craft one.
This issue affects Apache HTTP Server 2.4.51 and earlier.

*) SECURITY: CVE-2021-44224: Possible NULL dereference or SSRF in
forward proxy configurations in Apache HTTP Server 2.4.51 and
earlier (cve.mitre.org)
A crafted URI sent to httpd configured as a forward proxy
(ProxyRequests on) can cause a crash (NULL pointer dereference)
or, for configurations mixing forward and reverse proxy
declarations, can allow for requests to be directed to a
declared Unix Domain Socket endpoint (Server Side Request
Forgery).
This issue affects Apache HTTP Server 2.4.7 up to 2.4.51
(included).

Fix CVE-2021-33193: A crafted method sent through HTTP/2 will bypass
validation and be forwarded by mod_proxy, which can lead to request
splitting or cache poisoning. This issue affects Apache HTTP Server
2.4.17 to 2.4.48.

Fixes the following security vulnerabilities:
*) SECURITY: CVE-2019-0197 (cve.mitre.org)
mod_http2: fixes a possible crash when HTTP/2 was enabled for a http:
host or H2Upgrade was enabled for h2 on a https: host. An Upgrade
request from http/1.1 to http/2 that was not the first request on a
connection could lead to a misconfiguration and crash. Servers that
never enabled the h2 protocol or only enabled it for https: and
did not set "H2Upgrade on" are unaffected by this issue.

mod_http2: using fuzzed network input, the http/2 request
handling could be made to access freed memory in string
comparision when determining the method of a request and
thus process the request incorrectly. [Stefan Eissing]

MPMs unix: Fix a local priviledge escalation vulnerability by not
maintaining each child's listener bucket number in the scoreboard,
preventing unprivileged code like scripts run by/on the server (e.g. via
mod_php) from modifying it persistently to abuse the priviledged main
process. [Charles Fol <folcharles gmail.com>, Yann Ylavic]

Fixes the following security issues:
CVE-2017-3167: In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26,
use of the ap_get_basic_auth_pw() by third-party modules outside of the
authentication phase may lead to authentication requirements being bypassed.
CVE-2017-3169: In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26,
mod_ssl may dereference a NULL pointer when third-party modules call
ap_hook_process_connection() during an HTTP request to an HTTPS port.
CVE-2017-7659: A maliciously constructed HTTP/2 request could cause
mod_http2 to dereference a NULL pointer and crash the server process.
CVE-2017-7668: The HTTP strict parsing changes added in Apache httpd 2.2.32
and 2.4.24 introduced a bug in token list parsing, which allows
ap_find_token() to search past the end of its input string. By maliciously
crafting a sequence of request headers, an attacker may be able to cause a
segmentation fault, or to force ap_find_token() to return an incorrect
value.
CVE-2017-7679: In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26,
mod_mime can read one byte past the end of a buffer when sending a malicious
Content-Type response header.
While we're at it, use the upstream sha256 checksum instead of sha1.

[Thomas:
- Don't explicitly pass CC_FOR_BUILD and CFLAGS_FOR_BUILD, those are
already part of the default environment passed by the
autotools-package infrastructure.
- Explicitly disable Lua and LuaJIT support to avoid mis-detection of
host installation.
- Explicitly handle the optional support of libxml2, OpenSSL and
zlib. Especially, the absence of explicit handling for libxml2 was
causing a build failure due to the host libxml2 being detected.
- Remove /usr/manual and /usr/build from the target. This saves 20+
MB of target space.]
